Product Details

16/16/8AW-2.3 Product Description

The Bachmann EIK16/16-8AW/2.3 is a high-density, energy-optimized I/O controller module engineered for demanding industrial automation environments. Designed within Bachmann's proven EIK series platform, this module delivers 16 digital inputs, 16 digital outputs, and 8 analog outputs in a compact, DIN-rail-mountable form factor — purpose-built to reduce unnecessary power draw while maintaining deterministic control performance across smart production lines.

At NANKMOS, every unit is sourced directly, pre-shipment tested, and backed by a 12-month warranty, ensuring your automation infrastructure remains operational and energy-efficient from day one.

In modern industrial energy management, every node in the control architecture contributes to overall system efficiency. The Bachmann EIK16/16-8AW/2.3 is designed to integrate seamlessly into multi-tier automation topologies where power awareness is a first-class design requirement.

When paired with a Bachmann M1 CPU module — such as the MC206 or MC210 — the EIK16/16-8AW/2.3 participates in real-time energy profiling cycles. The CPU polls I/O states at deterministic intervals, enabling the control program to implement load-shedding routines that deactivate non-critical outputs during low-demand production windows. This reduces aggregate panel current draw without interrupting process continuity.

The module's 8 analog outputs (AW channels) are particularly valuable when interfacing with variable frequency drives (VFDs) such as the Bachmann-compatible ABB ACS series or Siemens SINAMICS G120. By issuing 0–10 V or 4–20 mA reference signals directly from the EIK16/16-8AW/2.3, the PLC program can modulate motor speed in real time — eliminating fixed-speed operation that wastes energy during partial-load cycles. This drive-level speed regulation is one of the most impactful levers for reducing motor energy consumption on conveyor, pump, and fan applications.

On the digital side, the 16 DO channels support direct switching of contactors, solenoid valves, and relay modules, enabling the PLC to implement sequenced startup logic that staggers inrush currents across multiple motor loads. This prevents simultaneous peak demand spikes that inflate energy billing and stress distribution infrastructure. When combined with a Bachmann power monitoring module (such as the EPC series), the system gains closed-loop visibility into per-phase current, voltage, and power factor — data that feeds directly into SCADA dashboards for energy KPI tracking.

The EIK16/16-8AW/2.3 also supports integration with HMI panels running on the same Bachmann M1 backplane or connected via Modbus TCP. Operators can visualize real-time I/O states, analog setpoints, and energy consumption trends from a single interface — reducing the need for manual field inspections and enabling faster response to abnormal load conditions. For facilities running SCADA platforms such as Wonderware, Ignition, or Bachmann's own SolutionCenter, the module's data is accessible via standard OPC-UA or Modbus TCP gateways, enabling enterprise-level energy reporting without additional hardware.

In sensor-dense environments, the 16 DI channels accept signals from proximity sensors, pressure switches, flow meters, and temperature transmitters, feeding process state data into the PLC for condition-based control decisions. Rather than running equipment on fixed timers, the control program responds to actual process conditions — a strategy that directly reduces unnecessary runtime and associated energy consumption. Paired with Bachmann communication modules supporting EtherCAT or CANopen, the EIK16/16-8AW/2.3 achieves sub-millisecond I/O update cycles, ensuring that energy-saving control actions are executed with the precision required for high-speed production lines.

Factory energy optimization is not a single-point solution — it is a system-level discipline that requires coordinated action across every layer of the control architecture. The Bachmann EIK16/16-8AW/2.3 contributes to this discipline at the field I/O layer, where the gap between efficient and inefficient control is most directly felt in energy bills and equipment wear.

By enabling the PLC to implement demand-responsive control logic, the EIK16/16-8AW/2.3 allows production lines to dynamically adjust equipment states based on real-time throughput requirements. During scheduled low-production windows — shift changes, material replenishment pauses, or recipe changeovers — the module's DO channels can systematically de-energize non-essential loads: auxiliary conveyors, cooling fans, lighting circuits, and idle actuators. This structured load management approach can reduce standby energy consumption by a measurable margin without requiring changes to the core production program.

The analog output channels play a critical role in thermal load management. By modulating VFD reference signals based on process feedback from temperature or pressure sensors connected to the DI channels, the control system maintains equipment within optimal thermal operating bands. This reduces heat generation in motor windings and drive power stages — extending component service life and reducing the frequency of thermal-related maintenance interventions. Lower thermal load also means reduced demands on panel cooling systems, which themselves represent a significant auxiliary energy cost in large control enclosures.

For production line takt time optimization, the EIK16/16-8AW/2.3 supports high-speed digital I/O scanning that enables the PLC to synchronize multi-axis motion sequences with minimal inter-cycle dead time. Tighter cycle synchronization means less time spent with motors energized but not performing useful work — a direct reduction in energy-per-part metrics. When integrated with servo drive systems via the Bachmann M1 platform's motion control libraries, the I/O module provides the discrete handshaking signals that coordinate pick-and-place, indexing, and clamping sequences with sub-millisecond precision.

Predictive maintenance integration is another key energy optimization pathway. By monitoring digital input signals from vibration sensors, current transducers, and bearing temperature probes, the PLC program running on the Bachmann M1 platform can detect early-stage equipment degradation before it manifests as unplanned downtime. Catching a failing bearing or a degrading motor insulation condition early allows maintenance teams to schedule interventions during planned stops — avoiding the energy waste and production loss associated with emergency shutdowns and cold restarts.

Every Bachmann EIK16/16-8AW/2.3 unit shipped from NANKMOS undergoes pre-shipment functional testing covering all DI, DO, and AW channels. This ensures that the module performs to specification from the moment it is installed, eliminating the energy waste and production disruption associated with field commissioning failures. With stock maintained and orders processed for rapid dispatch, your production line energy optimization project does not need to wait.

Q1: How does the EIK16/16-8AW/2.3 contribute to measurable energy savings on a production line?The module enables the Bachmann M1 PLC to implement demand-responsive load control — systematically de-energizing non-essential outputs during low-production periods and modulating VFD speed references via analog outputs to match actual process load. These two strategies, applied consistently, reduce both active and standby energy consumption across motor, actuator, and auxiliary loads.

Q2: Is the EIK16/16-8AW/2.3 compatible with third-party PLC platforms and SCADA systems?The module is natively designed for the Bachmann M1 automation platform. For integration with third-party SCADA systems such as Ignition, Wonderware, or Siemens WinCC, data is accessible via Modbus TCP or OPC-UA gateways supported by the Bachmann M1 CPU. Direct use with non-Bachmann PLC platforms is not the intended application; consult your system integrator for gateway-based integration options.

Q3: What is the recommended replacement or upgrade path if the EIK16/16-8AW/2.3 reaches end of service life?Within the Bachmann EIK series, modules share a common backplane and communication architecture, allowing like-for-like replacement without reprogramming the PLC application. For expanded I/O capacity or additional analog channels, Bachmann offers higher-density EIK variants that are backward-compatible with existing M1 system configurations. NANKMOS maintains stock of EIK series modules and can advise on availability and compatibility.

Q4: What testing is performed before shipment, and what does the 12-month warranty cover?Every unit undergoes pre-shipment functional testing of all 16 digital inputs, 16 digital outputs, and 8 analog output channels. The 12-month warranty covers manufacturing defects and functional failures under normal operating conditions. It does not cover damage resulting from incorrect installation, overvoltage events, or unauthorized modification. For warranty claims or technical support, contact NANKMOS directly.
