- Combines safe input evaluation and floating relay outputs
- Supports safety functions up to SIL 3 or Category 4 / PL e
- Uses pulse outputs for diagnostic sensor-line testing
X20SC2432 is a B&R safe digital mixed i/o module designed for the X20 System.
The module evaluates safety sensors and switches floating actuator circuits while pulse outputs support sensor-line diagnostics.
Before installation or replacement, verify the complete material number, the safety function, input and relay wiring, external load protection, switching voltage and inrush, software filters, test-pulse assignment, hardware revision, X20TB52, X20BM33 or X20BM36, and the validated SafeDESIGNER project.
Availability, condition, price, and shipping time for X20SC2432 are confirmed during quotation.

- Pulse outputs can reveal cross-circuits and wiring faults
- Input filters are configured as part of the validated safety response time
- Sensor wiring and test-pulse assignment must match the safety project
- Each safe output is a floating normally open relay contact
- Load voltage, continuous current and inrush must remain within the documented range
- External fuse or circuit-breaker protection is mandatory
- X20TB52 and a safety-keyed bus module are required
- Hardware revision and SafeDESIGNER project compatibility must be checked
- Every safe state, diagnostic and restart path must be validated on the machine
- Emergency-stop and guard-switch evaluation with floating contactor control
- Two-channel safety sensor monitoring with diagnostic test pulses
- Safety shutoff of AC or DC actuator circuits through monitored relay contacts
