Description
Overview
The IC695ALG626 HART Analog Input Module is part of GE’s PACSystems RX3i control platform, designed to acquire high‑accuracy analog signals while simultaneously supporting HART 5.0 digital communication on every channel. This module provides a flexible interface for a wide range of field transmitters used in process measurement and advanced diagnostics.
Functional Characteristics
The module accepts both current and voltage inputs, making it suitable for diverse instrumentation environments. It supports sixteen single‑ended channels or eight differential channels, allowing engineers to configure the module based on system requirements.
Supported input ranges include:
-
Current: 0–20 mA, 4–20 mA, ±20 mA
-
Voltage: ±10 V, 0–10 V, ±5 V, 0–5 V, 1–5 V
The IC695ALG626 includes LED indicators for module health, field wiring status, and terminal block connectivity. It is hot‑swappable within the RX3i universal backplane and requires no jumpers, simplifying installation and maintenance.
Performance and Diagnostics
The module incorporates:
-
Automatic calibration
-
Open‑circuit detection
-
Configurable alarm thresholds (high, low, rate‑of‑change)
-
Flash memory for firmware updates
-
HART digital data retrieval for device diagnostics
These features ensure stable, accurate signal acquisition and improved system reliability.
