- Controls four higher-current type A safety outputs
- Supports up to 2 A per channel with a 5 A total limit
- Monitors output current and open-circuit conditions
X20SO4120 is a B&R 4-channel 2 a safe digital output module designed for the X20 System.
The module controls higher-current safety relays, contactors, or valves while supervising the output circuit for diagnostic faults.
Before installation or replacement, verify the complete material number, actuator suitability for type A outputs, 2 A channel and 5 A total limits, inrush and thermal load, output suppression, test pulses, open-circuit threshold, safe-state behavior, X20TB52, X20BM33 or X20BM36, safety project, and validation record.
Availability, condition, price, and shipping time for X20SO4120 are confirmed during quotation.

- Each channel is rated 2 amperes but the module total is limited to 5 amperes
- Actuator inrush and cabinet temperature must be included in the calculation
- The potential-free load must suit the positive and negative switching architecture
- Current monitoring supports open-circuit detection
- Diagnostic test pulses can affect sensitive electronic loads
- Fault acknowledgment is controlled by the validated safety application
- Higher load current increases module and cabinet dissipation
- Horizontal and vertical mounting have different operating-temperature limits
- Wiring, conductor size, grouping, and enclosure cooling must be checked together
- Higher-current safety contactor and relay control
- Safety shutoff valves requiring up to 2 A per output
- Monitored actuator circuits with a 5 A total module load
