GE PACSystems RX3i IC695ALG112 – Analog Current Input Module for 4–20 mA Process Signals

The IC695ALG112 is a PACSystems RX3i analog input module designed for process current loops—typically 4–20 mA and 0–20 mA. It slots straight into an RX3i rack and gives you dense, reliable current measurement for transmitters on skids, utility systems, or plantwide analog I/O. From my experience, it’s a practical pick when you want straightforward current inputs without adding external signal conditioners all over the panel.

Key Features

• Multi‑channel current inputs – Suited for multiple 4–20 mA field transmitters in one slot, reducing rack footprint.
• Designed for RX3i – Installs in PACSystems RX3i baseplates with backplane-powered operation; no special carrier needed.
• Configurable ranges – Typically supports 4–20 mA and 0–20 mA per channel, so you can mix loop types in the same module.
• Noise‑aware front end – You might notice that stable readings are easier to maintain with proper shielding and grounding; the module’s input design helps a lot in many cases.
• Channel diagnostics – Loss‑of‑signal behavior (e.g., wire break on 4–20 mA) can be monitored and alarmed through the CPU logic.
• Removable field wiring – Service is faster; you don’t have to disturb the module when you need to swap it.
• Process‑focused use cases – Great for pressure, flow, and level transmitters on water/wastewater skids, boiler rooms, utilities, or OEM machinery.

Installation & Maintenance

• Cabinet & environment – Mount the RX3i rack in a ventilated enclosure meeting industrial panel standards. Keep ambient typically within 0–60°C and avoid high vibration zones.
• Wiring guidelines – Use shielded twisted pair for 4–20 mA runs. Land shields at one end (usually the cabinet side) to avoid ground loops. Separate low‑level analog from high‑voltage and VFD cabling.
• Loop power – Most 4–20 mA transmitters require 24 VDC loop supply. The module reads current; it does not usually power the loop. Check the transmitter’s burden and the module’s input resistance so the loop has enough headroom.
• Grounding – Tie shields and the panel ground bar cleanly; poor grounding is the first culprit for jittery readings in many cases.
• Commissioning – Verify channel range (0–20 mA vs 4–20 mA) in the RX3i configuration, then validate with a loop calibrator. One thing I appreciate is how quickly you can trim ranges and scaling in logic.
• Routine checks – Re‑torque terminal screws after thermal cycling, clean dust from the rack, and keep CPU firmware at a supported level. Annual loop verification with a calibrator is usually enough.
