Description
GE Fanuc IC670CHS001E High-Density Analog I/O Module
The IC670CHS001E is a high-performance analog input/output (I/O) module from GE Fanuc’s IC670 series, designed for industrial automation systems requiring precise signal conversion and rugged reliability. Supporting 16 analog inputs (4–20mA/±10V) and 8 analog outputs (4–20mA/±10V), this module delivers 16-bit resolution and ±0.1% accuracy, making it ideal for process control in manufacturing, energy, and water treatment applications.
1. Product Overview
The IC670CHS001E bridges the gap between analog sensors/actuators and GE Fanuc PLCs, enabling real-time monitoring of temperature, pressure, and flow. Its dual-layer isolation (2.5kV RMS) protects against voltage surges and EMI, while hot-swap capability minimizes downtime during maintenance. With -40°C to +70°C operating range and IP20-rated design, the module ensures stable performance in harsh environments.

6. Selection Recommendations
- Channel Requirements: Choose IC670CHS001E for mixed analog I/O; use IC670CHS002E for 16-input-only applications.
- Input Type: Opt for the -HI variant for ±20mA signals; select -LV for ±5V inputs.
- Environment: Pair with GE’s IC670CHS001E-H (IP65-rated) for outdoor or washdown areas.
7. Installation & Maintenance Notes
- Wiring: Use twisted-pair shielded cables (AWG 24–18) for RTD/TC inputs to minimize noise.
- Calibration: Perform annual factory calibration verification via GE’s Proficy software.
- Cooling: Install fans if ambient temperature exceeds +50°C in enclosed cabinets.
