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.
