What is the B&R X20CM1201?

Command-dependent digital pattern output

Counter-dependent output circuit

Event-controlled abort criteria

4 digital inputs

4 digital channels, configurable as inputs or outputs

The module can be used to configure and carry out simple movements. For this purpose, the module has one AB encoder input and a total of 8 digital channels. Four of them are inputs, and the other 4 can be set as either an input or an output. Various output bit patterns are stored directly in the module.

The module is perfectly suited for easy to create drive control tasks for program and event controlled motor movements. Feed movements using drives with 2 speeds and forward/reverse movement are created easily and efficiently.
