Product Details

IC695LRE001B Product Description

The GE IC695LRE001B is a high-performance Remote I/O Expansion Module engineered for the PACSystems RX3i platform, delivering reliable serial bus communication and seamless field device integration across distributed automation architectures. Designed for demanding industrial environments, the IC695LRE001B extends the reach of the RX3i backplane to remote I/O drops, enabling real-time data acquisition, deterministic signal transmission, and transparent device visibility from the field edge to the control room. Whether deployed in discrete manufacturing, process automation, or hybrid smart factory environments, this module serves as a critical data link node that bridges physical field signals with higher-level control, monitoring, and analytics systems.

In a modern smart factory, the IC695LRE001B functions as the backbone of a distributed I/O network, enabling the PACSystems RX3i controller to communicate with field devices located far from the main control cabinet. The data flow begins at the sensor and actuator layer — where proximity switches, pressure transmitters, temperature sensors, and motor feedback signals are wired into remote I/O modules at the drop location. The IC695LRE001B collects these signals and transmits them over the serial bus back to the RX3i CPU, such as the IC695CPU315 or IC695CPU320, which executes the control logic and updates output states in real time.

This architecture eliminates the need for long individual wire runs from every field device back to the central panel, dramatically reducing installation cost and improving signal integrity. The RX3i CPU then exchanges process data with upstream systems: an iFIX or CIMPLICITY SCADA server receives live I/O states for operator visualization, alarm management, and historical trending. HMI terminals — such as GE QuickPanel+ or third-party Weintek and Siemens TP series panels — display real-time process values sourced directly from the RX3i data table, which is continuously refreshed by the IC695LRE001B remote drop.

For multi-network environments, an IC695ETM001 Ethernet module installed in the same RX3i rack enables EtherNet/IP or SRTP communication to plant-level MES and ERP systems, while the IC695LRE001B handles the deterministic field-level data collection. Edge gateway devices — such as Moxa MGate protocol converters or Kepware OPC-UA servers — can bridge the RX3i data to cloud analytics platforms, enabling predictive maintenance dashboards and KPI visualization without disrupting the real-time control loop.

Variable frequency drives (VFDs) controlling conveyor motors, pumps, and fans report speed feedback and fault status through digital I/O modules at the remote drop, with the IC695LRE001B ensuring that every status bit reaches the CPU within the configured scan cycle. Alongside the IC695LRE001B, modules such as the IC694MDL340 discrete input module and IC694MDL754 discrete output module populate the remote rack, forming a complete field I/O node. For analog signal acquisition — 4–20 mA current loops from flow meters and level sensors — the IC694ALG220 analog input module integrates seamlessly into the same remote drop, with all data aggregated and forwarded by the IC695LRE001B to the RX3i CPU.

Industrial Ethernet switches — such as those from the Hirschmann MICE or Phoenix Contact FL SWITCH series — provide the network backbone connecting multiple RX3i racks, SCADA servers, and engineering workstations within the plant LAN. The IC695LRE001B's role in this architecture is foundational: it ensures that field-level data is captured accurately, transmitted reliably, and made available to every layer of the automation pyramid — from the PLC scan cycle to the enterprise dashboard.

Many industrial sites face persistent challenges with data fragmentation: legacy field devices speak proprietary protocols, remote I/O drops lack reliable communication paths, and operators have no real-time visibility into distributed equipment status. The IC695LRE001B directly addresses these pain points within the PACSystems RX3i ecosystem.

Protocol Unification: By standardizing field I/O communication over the GE serial bus architecture, the IC695LRE001B eliminates the need for ad-hoc protocol converters at each remote drop. All field signals — discrete, analog, and specialty — are aggregated at the remote rack and transmitted to the RX3i CPU using a single, deterministic communication channel.

Eliminating Data Islands: Remote equipment that previously operated in isolation — motors, valves, sensors at the far end of a production line — becomes fully visible to the SCADA system and HMI once connected through the IC695LRE001B. Operators gain live status, fault codes, and process values without requiring manual inspection rounds.

Remote Monitoring and Diagnostics: The RX3i platform's diagnostic capabilities, extended to the remote drop via the IC695LRE001B, allow maintenance engineers to identify communication faults, module health issues, and I/O errors from the engineering workstation or SCADA client — reducing mean time to repair (MTTR) and minimizing unplanned downtime.

Production Line Transparency: With every field signal routed through the IC695LRE001B and into the RX3i data table, SCADA historians can log every process event with millisecond-level timestamps. This data supports OEE analysis, shift reporting, and continuous improvement initiatives without requiring additional data collection hardware.

Alarm Tracking and System Expansion: Alarm conditions detected at the remote I/O drop are immediately propagated to the RX3i CPU and forwarded to the SCADA alarm management system, ensuring that no fault event is missed. As production capacity grows, additional remote drops can be added to the serial bus network, with each new IC695LRE001B node expanding the system's I/O capacity without requiring changes to the central control cabinet.

Q1: What is the communication latency of the IC695LRE001B in a PACSystems RX3i network? The IC695LRE001B operates within the deterministic scan cycle of the PACSystems RX3i CPU. Communication latency is governed by the configured RX3i scan time and the serial bus update rate, typically achieving sub-10ms I/O update cycles in standard configurations. This ensures that time-critical control applications — such as motor interlocks and safety shutdowns — receive accurate field data within every PLC scan.

Q2: Is the IC695LRE001B compatible with existing GE Series 90-30 or Series 90-70 I/O modules? The IC695LRE001B is designed for the PACSystems RX3i platform and is compatible with RX3i-series I/O modules. For integration with legacy Series 90-30 hardware, GE provides migration pathways through the PACSystems RX3i architecture; consult the GE PACSystems RX3i Hardware Reference Manual for specific module compatibility matrices and backplane configuration requirements.

Q3: How does the IC695LRE001B support remote diagnostics and network stability monitoring? The IC695LRE001B reports module health, communication status, and I/O fault conditions directly to the RX3i CPU's fault table. These diagnostics are accessible via the Proficy Machine Edition programming environment, SCADA OPC-DA/UA clients, and HMI data connections. Network stability is maintained through the serial bus's built-in error detection and retry mechanisms, with fault events logged for post-event analysis and predictive maintenance planning.
