B&R 7CM211.7 System 2003 Combination I/O and Counter Module
| Place of Origin | Germany |
| Brand Name | B&R |
| Model Number | 7CM211.7 |
Product Overview
The B&R 7CM211.7 is a multifunction combination module for the System 2003 automation platform. It integrates digital inputs, transistor outputs, counter or encoder processing, analog inputs and analog outputs into one module.
Its combined architecture is suitable for machines that need several signal types in a compact controller configuration. Exact replacement requires verification of the digital wiring, counter operating mode, analog signal range and terminal assignment.
Main Features
- 8 digital inputs for 24 VDC sink signals
- 4 ms digital input response specification
- 8 short-circuit-protected transistor outputs
- 24 VDC outputs rated up to 0.5 A per channel
- Three single-channel or two dual-channel counter configurations
- Alternative support for two incremental encoders
- Counter or encoder frequency up to 20 kHz
- Two 12-bit analog inputs and two 12-bit analog outputs

Maintenance and Replacement Notes
Confirm whether the existing application uses counters or incremental encoders and verify the analog channels as voltage or current inputs. The output loads, analog ranges, program configuration and terminal wiring must match the original installation.
The TB718 terminal blocks are ordered separately. Check whether the existing terminal blocks can be retained and whether their wiring labels remain consistent with the PLC program.
