- Combines four digital inputs and two protected digital outputs
- Includes one configurable analog input and one configurable analog output
- Adds two event counters and gate-time measurement for pulse-based tasks
X20CM8281 is a B&R universal mixed i/o module designed for the X20 System.
The module concentrates mixed field signals and simple pulse measurements where a compact station needs digital switching, analog acquisition, analog control, and counting together.
Before installation or replacement, verify the complete material number, digital input and output wiring, analog voltage or current terminal assignment, load and loop power, counter source and edge behavior, gate timing, X20TB12, a compatible bus module, and the saved channel configuration.
Availability, condition, price, and shipping time for X20CM8281 are confirmed during quotation.

- Voltage and current analog signals use different terminal assignments
- Software signal selection and engineering-unit scaling must match the physical wiring
- Digital input filtering is configurable to suit pulse or contact behavior
- Two digital inputs can operate as cyclic event counters
- Event counting evaluates documented negative signal edges at up to 20 kilohertz
- Input 4 supports gate-time measurement using a selectable internal counter frequency
- Digital outputs include thermal shutdown for overcurrent and short circuit
- Integrated protection supports switching inductive loads
- The analog output is short-circuit proof and uses an internal enable relay for startup and errors
- Compact machine stations requiring mixed digital and analog I/O
- Pulse-event counting from sensors or encoders up to 20 kilohertz
- Gate-time measurement combined with analog monitoring and control
