GE Fanuc IC698CHS217 Dual-Channel High

In stock

Product Overview:
The GE Fanuc IC698CHS217 is a 2-channel high-speed counter and frequency measurement module from the Genius I/O product line for the Series 90-70 PLC. It provides a cost-effective solution for applications requiring simultaneous monitoring of two axes, such as dual-axis tension control, dual-conveyor synchronization, and coordinated motion control. Each channel delivers 32-bit counting resolution at speeds up to 2 MHz, with full quadrature encoder support and non-volatile data retention.
