GE PACSystems RX3i IC695ALG508CA – 8-Channel Analog Input Module for reliable voltage/current signal acquisition (conformal coated)

The IC695ALG508CA is an 8-channel analog input module for the PACSystems RX3i platform. From my experience, it’s a straightforward way to bring mixed voltage and current signals into an RX3i rack when you need stable 16‑bit measurement and low noise, without overcomplicating configuration. The “CA” suffix indicates the conformal‑coated version, which typically holds up better in environments with humidity, dust, or mild corrosives—plant air handling rooms, wastewater skids, or coastal facilities are common examples.

Key Features

• 8 analog input channels – Suited for typical process signals; helps consolidate field points into a single-slot module.
• Voltage/current ranges – Supports common ranges such as 0–10 V, ±10 V, 0–20 mA, and 4–20 mA, making retrofits easier.
• 16-bit resolution – Provides fine granularity for slow- to medium-speed process measurements.
• Conformal coated (CA) – Added protection in high-humidity or mildly corrosive atmospheres, which in many cases reduces unexpected downtime.
• Noise-conscious design – Channel-to-backplane isolation and grounded shield practices typically keep readings stable in mixed-signal panels.
• RX3i backplane integration – Seamless with PACSystems RX3i CPUs; configuration via standard engineering tools.
• Front-wiring convenience – Field wiring lands on a front terminal interface, so you don’t need to pull the rack to service it.

Technical Specifications

Related and Supporting Products

• IC695CHS007 / IC695CHS012 / IC695CHS016 – 7-, 12-, and 16-slot RX3i baseplates; choose based on I/O count.
• IC695PSA040 / IC695PSD040 – RX3i power supplies (AC/DC input variants) sized for your rack load.
• IC695CPU310 (or similar RX3i CPUs) – Pairs with the module for logic execution and data handling.
• IC695ALG600 – Alternative RX3i analog input module with higher channel density; useful when cabinet space is tight.
• RX3i analog output options – 4- or 8-channel AO modules are available when you also need control signals to drives or valves.

You might notice that many teams standardize on the IC695CHS012 plus IC695PSA040; it seems to be a balanced choice for medium racks while keeping heat and budget reasonable. One OEM told us they swapped to the “CA” coated version after two humidity-related incidents and haven’t had a repeat issue since.

Installation & Maintenance

• Panel/cabinet environment – Mount the RX3i rack in a clean, ventilated enclosure. Keep ambient 0–60 °C and avoid corrosive gases. For the CA version, you still want good airflow.
• Wiring practices – Use shielded twisted pair for analog runs; land shields at one end only (typically at the panel). Route analog separately from high-voltage and VFD cables.
• Grounding – Maintain a low-impedance panel ground. Bond DIN rail and door grounds to reduce induced noise on low-level signals.
• Commissioning – Select input range per channel in the engineering tool, verify scaling, and perform a quick loop-check with a calibrated source (4–20 mA or 0–10 V).
• Maintenance – No routine calibration is typically required. Periodically inspect terminals, re-torque if needed, clean dust with dry air, and apply firmware updates to the CPU as recommended.
• Spare strategy – For critical lines, keeping one spare module on the shelf usually minimizes downtime; the conformal-coated version is a safer spare for mixed environments.

Quality & Certifications

• Certifications – CE marked; UL/cUL Listed; RoHS-compliant (typical for RX3i analog I/O).
• Manufacturer warranty – Standard manufacturer terms, complemented by our 365-day warranty on supply.
