Product Overview

The IC670ALG630 is an 8-channel thermocouple input module engineered for industrial process control racks. It accepts direct thermocouple wiring or low-level millivolt signals, performs cold-junction compensation, and delivers digital temperature or raw mV readings to a compatible host bus. The module is built for reliable continuous monitoring with on-board diagnostics and rack integration.

Key Technical Characteristics

• Channels: 8 independent thermocouple inputs

• Supported TC types: K, J, T, E, N, R, S, B (configurable per channel)

• A/D conversion: 15-bit resolution plus sign bit

• Measurement modes: temperature (tenths °C/°F) or direct millivolt (typical resolution 0.01 mV)

• Cold-junction compensation: per-module automatic compensation

• Diagnostics: open-circuit thermocouple detection, out-of-range alarm, channel fault reporting

• Isolation & front-end: optically coupled multiplexer for channel isolation and noise rejection

• Integration: compatible with GE/FANUC-style bus interface modules (Genius Bus or equivalent)

• Environmental & mechanical: approximate weight 0.36 kg; dimensional footprint ~18.5 × 7 × 5 cm

• Regulatory/handling: HS Code 8537101190; new, in-stock unit, origin USA

Operational Use Cases

• Multi-point temperature acquisition in chemical, petrochemical and food processing plants

• High-resolution thermocouple monitoring for furnaces, kilns and heat-treatment lines

• Retrofit I/O expansion for GE/FANUC-compatible DCS and PLC racks

• Distributed sensing applications requiring per-channel diagnostics to improve uptime

• Laboratory and pilot-plant systems where both temperature and mV logging are needed

Typical Integration Notes

• Requires a compatible rack and bus interface module; confirm host supports IC670-series addressing

• Configure thermocouple type and reporting mode in the host I/O configuration tool before commissioning

• Use shielded cabling and appropriate grounding to minimize noise on millivolt inputs

• Schedule periodic calibration of thermocouples and verification of cold-junction compensation
