GE IC694ALG222GE

Product Overview

The IC694ALG222GE is a high‑density 16‑channel analog voltage input module from GE Fanuc (Emerson Automation) for PACSystems RX3i PLCs, offering 16 single‑ended or 8 differential voltage inputs configurable per channel to 0–10V (unipolar) or -10–+10V (bipolar) ranges. It delivers 12‑bit resolution, ±0.25% full‑scale accuracy at 25°C, and ±0.5% full‑scale accuracy over the operating range, with 6ms update for all 16 single‑ended channels or 3ms for all 8 differential channels. The module provides 1500VAC input‑to‑backplane isolation, 41Hz/82Hz selectable input filters, and LED diagnostics (Module OK, Power, Channel Faults). It fits any RX3i I/O slot, requiring +5VDC backplane power (112mA) and isolated +24VDC external power (41mA), converting voltage signals from sensors/transmitters into digital data for real‑time process control in industrial environments.

Functional Features

  • Dual Channel Modes: 16 single‑ended (ground‑referenced) or 8 differential (EMI‑resistant) channels for flexible wiring.
  • Per‑Channel Range Configuration: Software‑selectable 0–10V / -10–+10V per channel for mixed‑range sensor networks.
  • 12‑Bit Resolution: 2.5mV (0–10V) / 5mV (-10–+10V) LSB for precise measurement.
  • Fast Update Rates: 6ms (16 single‑ended) / 3ms (8 differential) for real‑time control.
  • Selectable Filtering: 41Hz (single‑ended) / 82Hz (differential) to suppress noise in industrial environments.
  • 1500VAC Isolation: Blocks noise/transients between inputs and backplane for reliable data acquisition.
  • LED Diagnostics: Module OK, Power, and per‑channel Fault indicators for quick troubleshooting.
  • Hot Swap Capable: Replace without system shutdown (RX3i baseplate‑dependent).
  • Low Power Consumption: 112mA +5VDC (backplane) and 41mA +24VDC (isolated external).
  • High Input Impedance: 10 MOhms minimizes loading on sensors/transmitters.

Application Scenarios

  • Process Automation: Monitors pressure, flow, level, and temperature transmitters (0–10V / -10–+10V) in chemical, oil/gas, and water treatment plants.
  • Manufacturing Lines: Captures analog data from weigh scales, position sensors, and tension controllers in automotive, packaging, and semiconductor fabrication.
  • HVAC & Building Automation: Measures air flow, temperature, and humidity in industrial facilities with differential wiring for noise immunity.
  • Test & Measurement: Acquires 16 channels of voltage data from strain gauges, accelerometers, and power analyzers.
  • Renewable Energy: Monitors solar panel voltage, wind turbine pitch control, and battery bank levels in wind/solar farms.
  • Marine & Offshore: Complies with ABS/BV/DNV approvals for shipboard process monitoring in Zone 2 hazardous areas.
  • Retrofit Projects: Upgrades legacy RX3i systems for high‑channel‑count voltage monitoring with minimal wiring changes.

Ordering & Compatibility

Standard model: IC694ALG222GE. Compatible with all RX3i baseplates, CPUs, and I/O modules; fits any I/O slot. Requires +5VDC backplane power (112mA) and isolated +24VDC external power (41mA). Use shielded twisted‑pair cables for differential wiring; unshielded for single‑ended in low‑noise environments. Pair with terminal blocks (TB1) for field connections; no internal battery required.
