In chemical processing, power generation, and test facilities where field transmitters and sensors deliver both process values and diagnostic data over shared wiring without separate communication networks, the GE IC695ALG626-CA combines high-density analog acquisition with embedded HART protocol support for PACSystems RX3i controllers.
It serves industrial automation applications like distillation columns tracking levels/pressures via 4-20 mA while extracting HART device variables for predictive maintenance, or turbine auxiliaries polling vibration and temperature with status alerts—all through 16 single-ended or 8 differential channels in one slot.
Product Introduction & Positioning
The GE IC695ALG626-CA is a 16/8-channel non-isolated differential analog input module with HART 5.0 communications for GE Emerson PACSystems RX3i universal backplanes, configuring channels independently for voltage (±10/0-10/±5/0-5/1-5 V) or current (0-20/4-20/±20 mA). Four internal HART modems enable bidirectional multidrop polling, delivering 24-bit ADC data as 32-bit float/integer plus HART secondary/tertiary variables to %AI registers via Proficy Machine Edition.
In RX3i architectures, it mounts hot-swappable (firmware-dependent) with software auto-calibration, supporting up to 512 ms scans while prioritizing HART traffic. It pairs with outputs like IC695ALG728 for closed loops with diagnostics.
Integrators position it for HART-enabled brownfield upgrades, consolidating analog + digital data streams without I/O multipliers or multiplexers.
Key Technical Features & Functional Benefits
Sixteen single-ended (or eight differential) channels update via configurable filters (8-500 Hz) with 24-bit resolution converted to floating-point or 16-bit integer, enabling 0.05-0.3125% accuracy across ranges. Four HART modems poll devices asynchronously, extracting PV/SV/TV/QV/status without interrupting analog scans.pdfsupply+1
Rugged design draws 600 mA @3.3 V/450 mA @5 V (4.5 W max) for 0-60°C operation with 120 dB CMRR at 50/60 Hz, mounting via standard terminal blocks. Diagnostics include underrange/overrange, open-wire, and HART fail states piped to PLC bits.
Proficy configures HART schedules and scaling; non-isolated design suits clean signal environments. Thermal derating applies in current mode per datasheet curves.

Installation Notes & Maintenance Best Practices
Wire GE IC695ALG626-CA transmitters single-ended with shields grounded at module, configuring HART polling intervals in Proficy pre-scan. Verify no CM noise via filter sweeps; baseline secondary variables during commissioning.
Monthly HART status checks for device health; quarterly full-range calibration. Hot-swap supported on later revisions.
