Description
Product Overview
The GE IC695ALG600LT is a specialized 8-channel RTD/thermocouple input module designed for GE’s PACSystems RX3i platform, delivering high-precision temperature monitoring in industrial automation systems. This module supports versatile sensor inputs, including RTDs (Pt385, Ni672, Cu426) and thermocouples (J/K/T/E types), with 16-bit resolution and ±0.125% accuracy for critical applications like chemical processing and power generation. Engineered for harsh environments, the IC695ALG600LT features channel-to-channel isolation (1500V AC), IP67 protection (with cover), and an extended operating temperature range (-40°C to +70°C) . Its universal input channels allow flexible configuration for voltage (±10V), current (0–20mA), or resistance (0–4000Ω) signals, eliminating external signal conditioners. Integrated cold-junction compensation (CJC) and six software-configurable filter frequencies (8 Hz to 1000 Hz) ensure noise immunity in electrically noisy settings like substations or manufacturing plants . Compatible with GE’s Proficy Machine Edition software, the IC695ALG600LT enables predictive maintenance and real-time process optimization, reducing downtime and operational costs.

Key Features and Advantages
Multi-Signal Flexibility:
Each of the eight input channels independently configures for RTD, thermocouple, voltage, or current signals, eliminating external signal conditioners and reducing system complexity . Automatic cold-junction compensation ensures thermocouple accuracy, while configurable filters (8–1000 Hz) suppress noise in environments with heavy machinery or VFDs .
Industrial Robustness:
Dual isolation barriers (1500V AC between channels) prevent ground loops and electromagnetic interference, critical in power plants or oil refineries . The module withstands extreme temperatures (-40°C to +70°C) and 15G mechanical shocks, making it suitable for mobile equipment or offshore platforms .
Operational Efficiency:
Hot-swap capability allows module replacement without system shutdown. Onboard diagnostics detect open circuits, shorts, and overrange faults, with status LEDs and Proficy software integration enabling rapid troubleshooting .
Application Areas
- Chemical Processing: Monitors reactor temperatures via Pt RTDs in ATEX-certified hazardous zones, ensuring safety during exothermic reactions .
- Power Generation: Tracks turbine bearing temperatures using K-type thermocouples, triggering shutdowns before mechanical failure .
- Water Treatment: Measures pipe corrosion via 0–2000Ω resistance inputs in pump stations, optimizing maintenance schedules .
- Pharmaceuticals: Ensures FDA-compliant temperature logging for sterilization autoclaves with ±0.1°C stability .

Installation and Maintenance
Installation Preparation: Mount in an RX3i universal backplane (e.g., IC695CHS012). Use shielded twisted-pair cables grounded at one end; separate high-voltage wiring by ≥15cm to prevent interference . Verify firmware ≥V2.80 and install terminal block IC694TBB032 for RTD inputs .
Maintenance Recommendations: Calibrate annually with traceable resistance/voltage standards. Clean terminals quarterly with isopropyl alcohol to prevent oxidation-induced drift. Replace if “Module Fault” LED persists or after 10 years of service .
