The Omron NX-ECS112 Machine Automation Controller SSI Position Interface Unit provides 1 channel for acquiring position data from compatible absolute encoders. It supports RS-422-A communication with a maximum data length of 32 bits and includes a 24 VDC encoder power supply rated at 0.3 A per channel. Differential communication supports reliable position-data transmission, while screwless push-in terminals provide the specified wiring interface. The NX-ECS112 integrates SSI encoder feedback into modular NX control architectures where absolute position information is required. It extends the PLC position control range available for Omron machine control systems.
