Description
1 ABR incremental encoder 24 V, differentialEncoder input monitoring2 additional inputs, e.g. for latch input24 VDC and GND for encoder supplyNetTime timestamp: Counter change
The module is equipped with 1 input for an ABR incremental encoder with 24 V encoder supply. The encoder inputs are monitored (A, B, R, A, B, R). The module is suitable for incremental encoders with symmetrical push-pull outputs.The plug-in module does not come equipped with line terminating resistors. For this reason, it is possible to connect encoders with low output current; nevertheless, the module is suitable only for low counter frequencies or short encoder cables due to possible line reflections.
