GE  IC695ALG608 – 8‑Channel Analog Current Input Module for 0/4–20 mA Signals

The IC695ALG608 is a solid fit when you need clean, stable acquisition of industrial 0/4–20 mA process signals on a PACSystems RX3i platform. From my experience, it’s typically used to bring in pressure, level, flow, and valve position transmitters without fuss, while keeping configuration straightforward in Proficy Machine Edition. You might notice that scaling and basic diagnostics are handled per channel, which helps maintenance teams spot wiring or sensor issues early.

• Payment: 50% advance payment; balance before delivery
• Shipping: FedEx, UPS, or DHL express

Key Features

• 8-channel current input (0/4–20 mA): Ideal for common process transmitters across water, chemicals, energy, and food plants.
• 16-bit conversion (typical): Stable measurement for trending and closed-loop control where small drifts matter.
• Per‑channel scaling & alarms: Configure engineering units and basic limits directly in the RX3i project to reduce PLC logic overhead.
• 2‑wire and 4‑wire transmitter support: Use external 24 VDC loop power for 2‑wire devices; 4‑wire instruments connect directly.
• Noise filtering: Configurable filtering options help smooth noisy signals in high‑EMI environments.
• Diagnostic flags: Out‑of‑range and wiring fault indications make field troubleshooting faster in most cases.
• RX3i rack integration: No special interface cards—communicates over the standard RX3i backplane.

Technical Specifications

Related or Supporting Products

• IC695ALG708 – 8‑ch analog current input with HART support (for plants standardizing on HART diagnostics).
• IC695ALG616 – Higher channel‑density analog input option (for cabinets tight on rack slots).
• IC695ALG704 – Voltage‑range analog input module if your instruments output ±10 V or similar ranges.

If you’re migrating from older Series 90‑30 I/O, this module is a common landing spot when modernizing to RX3i while keeping existing 4–20 mA loops intact.

Installation & Maintenance

• Cabinet & environment: Install in a ventilated enclosure meeting industrial cabinet standards; keep within 0–60 °C and avoid condensation.
• Wiring practices: Use shielded twisted pair for current loops; land shields at one end to reduce ground loops; separate low‑level analog from high‑voltage or VFD cabling.
• Loop power: Provide a clean 24 VDC supply for 2‑wire transmitters; fuse each loop individually for safer service.
• Grounding: Bond rack and panel grounds properly; maintain a low‑impedance earth reference.
• Commissioning: Verify channel ranges and scaling in Proficy; simulate a known 12 mA/20 mA signal to confirm calibration before going live.
• Routine care: Periodically check terminal tightness, clean dust with dry air, and review diagnostic/alarm logs. Firmware updates are rare but worth applying during planned outages.

A customer in a membrane filtration plant mentioned that enabling modest input filtering on the IC695ALG608 cleared up pump‑induced noise during ramp changes—small tweak, big improvement in trends.
