In high-precision process control and mixed-signal environments like chemical reactors, test benches, and HVAC optimization where diverse sensors demand flexible acquisition without dedicated modules per type, the GE IC695ALG600-AB consolidates universal analog inputs for PACSystems RX3i controllers.
It excels in industrial automation for batch blending, furnace profiling, and compressor monitoring that mix thermocouples from hot sections, RTDs on bearings, 4-20 mA transmitters on flows, and 0-10 V positioners—all consolidated into one rack slot with sigma-delta conversion delivering 16-bit data plus comprehensive diagnostics.
Product Introduction & Positioning
The GE IC695ALG600-AB is an 8-channel universal analog input module (two groups of four) plus two dedicated cold junction compensation inputs for GE Emerson PACSystems RX3i, configuring independently per channel for voltage (±10 V/0-10 V), current (±20/4-20 mA), thermocouple (B/C/E/J/K/N/R/S/T), RTD (PT385/3916/Ni/Cu), or resistance (up to 4000 Ω). It mounts in universal backplanes, feeding high-resolution %AI words to CPUs via PCI bus with Proficy Machine Edition handling scaling and filters (8 Hz to 1 kHz).
In RX3i systems, it supports hot-swap and group isolation for maintenance without process upset, pairing naturally with outputs like IC695ALG800. Firmware 6.00+ unlocks full diagnostics including open-wire and rate-of-change alarms.
Integrators favor it as the “Swiss Army knife” for brownfield upgrades, slashing panel space 50% versus type-specific cards while preserving signal integrity through 250 VAC isolation.
Key Technical Features & Functional Benefits
Channels flex across types with 16-bit resolution (32-bit float/integer formats) and configurable filters rejecting plant noise, updating <2 ms/channel (40 ms/group) via parallel sigma-delta A/Ds—critical for PID cascades tracking turbine exhaust or reactor beds.
Hardware shrugs 0-60°C abuse with 425 mA @5 V/400 mA @3.3 V draw (5.4 W max), front LEDs signaling OK/field faults/terminal status, and auto-calibration on power-up. Diagnostics pipe over/under-range, open-circuit, and ROC faults to PLC bits for runtime alerting.
RX3i-native with PCI backplane acceleration, it requires IC694ACC600 terminal blocks and supports disabled channels to shorten scans. MTBF >250k hours via coated boards in 95% RH cabinets.
