■ Overview
Technical properties
• Counter module for ET 200SP
• Interfaces:
- 24 V encoder signals A, B and N from P, M or
push-pull-switching encoders and sensors
- 24 V encoder supply output, short-circuit proof
- 3 digital inputs for controlling the count operation, for saving
or for setting the count value
- 2 digital outputs for fast reactions regardless of the counter
status or measured value
