ULTRA SLIMPAK G128 Product Description

The Moore Industries G128 Ultra SlimPAK is a precision industrial network interface and signal conditioner engineered for the demanding data-flow requirements of modern smart factories. Designed to bridge field-level instrumentation with supervisory control and data acquisition systems, the G128 delivers reliable 4–20 mA signal isolation, protocol conversion, and real-time data transmission across multi-vendor automation architectures. Whether deployed in process plants, discrete manufacturing lines, or hybrid automation environments, the G128 serves as a critical node in the industrial data chain — connecting sensors, PLCs, remote I/O modules, HMI panels, SCADA gateways, and edge computing platforms into a unified, transparent network.

In today's connected factory, data integrity from the field device to the control room is non-negotiable. The G128 Ultra SlimPAK addresses this by providing galvanic isolation between input and output signal loops, eliminating ground loops and noise interference that commonly corrupt 4–20 mA signals in electrically noisy industrial environments. Its ultra-slim DIN-rail form factor allows dense panel installations without sacrificing thermal performance or signal accuracy, making it an ideal fit for marshalling cabinets, junction boxes, and compact control enclosures.

The G128 Ultra SlimPAK occupies a pivotal position in the smart factory data flow architecture. At the field level, process sensors — including pressure transmitters, temperature sensors (4–20 mA output), flow meters, and level transmitters — generate analog signals that must be accurately conditioned before entering the control network. The G128 receives these raw 4–20 mA signals, isolates them from ground potential differences, and retransmits a clean, accurate analog signal to the next layer of the automation hierarchy.

In a typical deployment, the conditioned output from the G128 feeds directly into the analog input cards of a Siemens S7-300 or S7-1500 PLC, or into the I/O modules of an Allen-Bradley ControlLogix system. From there, the PLC processes the signal data and communicates upstream via PROFINET or EtherNet/IP to the plant's SCADA server. Operators monitoring a Wonderware InTouch HMI or Ignition SCADA platform receive real-time process values with full signal fidelity — a result made possible by the G128's precision isolation stage.

For installations using distributed remote I/O architectures, the G128 integrates seamlessly alongside Moore Industries NET Concentrator System (NCS) modules, which aggregate multiple analog channels and transmit data over Modbus RTU or Modbus TCP to the DCS or SCADA host. This combination is particularly effective in large-scale process plants where field instruments are located hundreds of metres from the control room, and where signal integrity over long cable runs is critical.

In smart factory edge computing scenarios, the G128's isolated analog output can be wired to the analog input of an industrial edge gateway — such as a Moxa MGate or Red Lion Data Station — which then converts the 4–20 mA value into a digital data stream for transmission over OPC-UA or MQTT to cloud-based MES or ERP platforms. This enables real-time production KPI dashboards, predictive maintenance analytics, and digital twin data feeds without requiring changes to the existing field wiring infrastructure.

Variable frequency drives (VFDs) and servo drive systems also benefit from the G128's signal conditioning capability. When a Siemens SINAMICS G120 or ABB ACS880 drive outputs a 4–20 mA speed reference or feedback signal, the G128 can isolate and retransmit this signal to a PLC analog input, preventing drive-induced electrical noise from corrupting the control loop. Similarly, in energy management applications, the G128 conditions current transformer (CT) output signals for integration with power monitoring SCADA systems, enabling real-time energy consumption tracking at the machine or production cell level.

Industrial Ethernet switches — such as the Hirschmann RS20 or Moxa EDS-308 — form the network backbone that carries digitised process data from PLCs and edge gateways to the SCADA server. While the G128 operates at the analog signal layer, its role in ensuring clean, accurate analog data is foundational to the quality of all downstream digital data. A corrupted 4–20 mA signal at the field level propagates as inaccurate process values throughout the entire SCADA/MES data chain — the G128 eliminates this risk at source.

Protocol Inconsistency: Many brownfield automation sites operate a mix of legacy 4–20 mA instrumentation alongside modern digital fieldbus devices. The G128 Ultra SlimPAK bridges this gap by conditioning and isolating analog signals so they can be accurately ingested by both legacy DCS analog input cards and modern PLC systems with HART-enabled I/O modules. This eliminates the need for costly field instrument replacement during system upgrades.

Data Islands and Signal Noise: Ground loops and common-mode noise are among the most persistent causes of data islands in process automation — where field instrument readings appear unreliable or inconsistent at the control system level. The G128's three-way galvanic isolation (input, output, power) breaks ground loops definitively, ensuring that sensor data from isolated field loops reaches the PLC or DCS with full accuracy, eliminating phantom readings and enabling reliable alarm management.

Remote Monitoring and Diagnostics: In remote or unmanned installations — pipeline monitoring stations, water treatment facilities, offshore platforms — the G128 ensures that 4–20 mA signals from field transmitters are accurately conditioned before transmission to remote SCADA systems. Combined with a Modbus-capable RTU or edge gateway, operators can perform remote diagnostics, verify signal health, and detect sensor drift without dispatching field technicians, reducing operational costs and improving uptime.

Production Line Transparency and Alarm Tracking: Accurate, noise-free analog signals are the foundation of effective alarm management in SCADA/HMI systems. By ensuring signal integrity at the field level, the G128 reduces nuisance alarms caused by signal noise, enabling operators to focus on genuine process deviations. This directly supports ISA-18.2 alarm management best practices and improves overall production line transparency.

System Expansion: The G128's DIN-rail form factor and wide operating temperature range make it straightforward to add additional signal conditioning channels as production lines expand. New field instruments can be integrated into existing SCADA architectures without rewiring or reconfiguring the control system — simply add G128 modules to the marshalling cabinet and connect to available PLC analog input channels.

Q1: Does the Moore Industries G128 Ultra SlimPAK introduce communication latency into the control loop? The G128 is an analog signal conditioner, not a digital protocol converter, so it does not introduce digital communication latency. Signal propagation through the isolation stage is effectively instantaneous relative to PLC scan times, making it fully compatible with fast-response control loops in process automation applications.

Q2: Is the G128 compatible with HART-enabled field instruments and HART pass-through to the control system? The G128 Ultra SlimPAK is designed for 4–20 mA signal isolation and conditioning. HART signal pass-through capability is model-dependent — please confirm the specific G128 variant against your HART communication requirements. For full HART multiplexing and asset management integration, Moore Industries offers dedicated HART interface solutions that complement the G128 in multi-instrument marshalling applications.

Q3: How does the G128 support network stability in electrically noisy industrial environments? The G128's galvanic isolation eliminates ground loops and common-mode noise — the primary sources of signal instability in industrial 4–20 mA networks. By breaking the electrical connection between input and output signal loops while maintaining accurate signal transmission, the G128 ensures that VFD switching noise, motor inrush currents, and high-voltage equipment interference do not corrupt process data at the PLC or SCADA level.
