Product Details

1715-TASOF8 Product Description

The Allen-Bradley 1715-TASOF8 is a high-reliability redundant analog output module engineered for energy-conscious industrial automation environments. Designed to integrate seamlessly within the 1715 Redundant I/O System, this module delivers precise signal output control that directly supports load management, motor drive regulation, and energy-efficient production line operation. With eight analog output channels and full redundancy architecture, the 1715-TASOF8 ensures uninterrupted process control — eliminating costly downtime and reducing the energy penalties associated with unplanned restarts and equipment re-initialization cycles.

In modern smart manufacturing facilities, every control node contributes to the overall energy profile of the production line. The 1715-TASOF8 plays a critical role in this ecosystem by providing stable, accurate analog outputs to variable frequency drives (VFDs), servo drive systems, and proportional control valves. By maintaining precise output signals, it enables drives and actuators to operate at optimal efficiency points rather than defaulting to full-load operation — a key strategy for reducing unnecessary energy consumption across motor-driven systems.

The 1715-TASOF8 is purpose-built for integration within Rockwell Automation's ControlLogix platform, where it works in concert with a broad ecosystem of energy-aware components. In a typical smart production line deployment, the module's analog outputs connect directly to PowerFlex 755 variable frequency drives, enabling precise speed and torque regulation of AC induction motors. Rather than running motors at fixed full-load speeds, the 1715-TASOF8 delivers dynamic 4–20 mA command signals that allow the PowerFlex 755 to modulate motor output in real time — reducing energy draw during low-demand production phases by 20–40% compared to across-the-line starting methods.

Within the same control architecture, the 1715-TASOF8 operates alongside the 1715-AENTR EtherNet/IP Adapter, which manages redundant communication between the I/O modules and the ControlLogix L7x or L8x series controller. This communication backbone ensures that energy control commands are transmitted with deterministic timing, preventing signal delays that could cause drives to operate inefficiently or overshoot setpoints. The 1756-EN2T EtherNet/IP communication module further extends this network, connecting the control system to SCADA platforms and energy management systems (EMS) for plant-wide power monitoring and demand response coordination.

For power quality monitoring, the 1715-TASOF8 is frequently deployed alongside the PowerMonitor 5000 power measurement unit, which captures real-time data on voltage, current, power factor, and harmonic distortion at the drive and motor level. This data feeds back into the ControlLogix controller via EtherNet/IP, enabling closed-loop energy optimization strategies where the 1715-TASOF8's output signals are automatically adjusted based on live power consumption readings. The result is a self-regulating energy control loop that continuously minimizes waste without operator intervention.

On the human-machine interface layer, PanelView Plus 7 HMI terminals display real-time energy dashboards sourced from the ControlLogix system, giving operators immediate visibility into drive loading, output channel status, and energy consumption trends. Operators can adjust production line speed setpoints directly from the HMI, with changes propagated through the ControlLogix program to the 1715-TASOF8 outputs and downstream to the connected drives and actuators. This closed-loop control chain — from HMI to PLC to I/O module to drive — is the foundation of energy-efficient smart manufacturing.

The 1715-TASOF8 also interfaces with Kinetix 5700 servo drive systems in applications requiring high-precision motion control with energy recovery capability. Kinetix 5700 drives support regenerative braking, returning energy to the DC bus during deceleration phases. The 1715-TASOF8's stable analog output commands ensure that servo motion profiles are executed smoothly, minimizing the aggressive acceleration and deceleration cycles that generate excess heat and increase energy consumption. In multi-axis production lines, this coordination between the 1715-TASOF8 and Kinetix 5700 drives can yield measurable reductions in peak demand charges.

Industrial facilities operating continuous or semi-continuous production lines face persistent challenges in balancing throughput targets with energy cost management. The 1715-TASOF8 addresses these challenges at the control signal level — the point where energy decisions are made and executed. By providing eight independent, redundant analog output channels, the module enables granular control over every energy-consuming actuator and drive on the line, from conveyor motors and pump drives to heating elements and pneumatic valve positioners.

One of the most significant energy optimization contributions of the 1715-TASOF8 is its role in eliminating control signal failures that force drives into fault states. When a non-redundant I/O module fails, connected drives typically default to a safe stop condition, requiring a full restart sequence that consumes significant inrush energy and disrupts production rhythm. The 1715-TASOF8's hardware redundancy architecture ensures automatic, bumpless switchover to the backup module in the event of a primary module fault — maintaining continuous analog output signals to drives and actuators without interruption. This capability directly reduces the frequency of energy-intensive restart events and protects production line takt time.

In energy management system (EMS) integrations, the 1715-TASOF8 serves as the execution layer for demand response strategies developed at the SCADA or MES level. When the EMS identifies a peak demand window or receives a utility demand response signal, it can instruct the ControlLogix controller to reduce motor speeds across the production line by modifying the setpoints delivered through the 1715-TASOF8's output channels. This coordinated load shedding — executed in milliseconds through the EtherNet/IP network — allows facilities to reduce peak demand charges without halting production, a critical capability for energy-intensive industries such as automotive, food and beverage, and chemical processing.

Predictive maintenance integration further enhances the energy optimization value of the 1715-TASOF8. By correlating analog output command values with motor current feedback from 1715-series analog input modules and PowerMonitor 5000 data, the ControlLogix system can detect early signs of motor degradation — such as increasing current draw at a fixed speed setpoint — that indicate rising mechanical friction or winding resistance. Early detection enables maintenance teams to schedule interventions before failures occur, avoiding both unplanned downtime and the energy waste associated with motors operating in degraded states. All 1715-TASOF8 modules supplied by NANKMOS are fully tested prior to shipment and backed by a 12-month warranty, ensuring reliable performance from day one of installation.

Q1: How does the 1715-TASOF8 contribute to measurable energy savings on a production line? The 1715-TASOF8 enables precise analog output control to variable frequency drives and servo systems, allowing motors to operate at demand-matched speeds rather than fixed full-load conditions. In combination with PowerFlex 755 VFDs and a ControlLogix energy management program, facilities typically achieve 15–35% reductions in motor energy consumption during partial-load production phases. The module's redundancy architecture also eliminates energy-intensive restart cycles caused by I/O module failures.

Q2: Is the 1715-TASOF8 compatible with existing ControlLogix and GuardLogix systems? Yes. The 1715-TASOF8 is designed for the 1715 Redundant I/O System and integrates natively with ControlLogix L7x and L8x series controllers via the 1715-AENTR EtherNet/IP Adapter. It is fully compatible with Studio 5000 Logix Designer programming software and supports standard Add-On Instructions (AOIs) for rapid integration into existing control programs. No additional communication hardware is required for systems already running EtherNet/IP infrastructure.
