Common Applications
Product Precautions
B&R X20SC0842 is x20 safe digital mixed module. It combines safe digital inputs, pulse outputs and safe semiconductor outputs for distributed machine-safety functions.
- Acquires eight safe Type A inputs
- Provides four 3 A safe Type A outputs
- Provides two safe low-current Type B2 outputs
- Supports OSSD test-pulse diagnostics
X20SC0842 operates with X20 safety bus base, 24 V DC safety field circuits, SafeLOGIC project, approved safety sensors and final elements.
Engineered applications include Emergency-stop input and output control, Guard-door safety monitoring, Safety-valve command, Distributed safety I/O renewal.
Important Notice: Confirm SafeDESIGNER channel mapping, test-pulse assignment, output load and proof-test sequence before enabling the safety application.
Apter Power X20SC0842 Manuals and Guides
Apter Power X20SC0842 Product and System Technical Reference PDFApter Power X20SC0842 Installation and Commissioning Workbook PDFThe first document presents model-specific engineering data. The second provides a separate installation, connection, commissioning and acceptance workflow.
Emergency-stop input and output control
Combines safe input evaluation with controlled shutdown outputs.
Guard-door safety monitoring
Monitors protective doors through the validated safety application.
Safety-valve command
Commands a documented safe final element within the channel rating.
Distributed safety I/O renewal
Replaces the exact mixed module while retaining safety validation.
Read the applicable B&R instructions before work. Verify X20SC0842 and the installed B&R X20 safety I/O configuration.
1
Verify the full X20SC0842 marking and its assigned B&R X20 safety I/O position before work.
2
Place the connected machine or process in the approved maintenance state.
3
Isolate the applicable supply and safe digital inputs and 24 v dc safety outputs field energy before disconnecting conductors.
4
Record connector, conductor, address and software identities before removal.
5
Use ESD controls and protect keyed interfaces, exposed contacts and electronic assemblies.
6
Confirm the installed X20 safety bus base and 24 V DC safety field circuits against the approved project.
7
Restore power in a controlled sequence and review device, network and host diagnostics.
8
Prove the intended emergency-stop input and output control function and retain the final test result.
Technical notes
Confirm SafeDESIGNER channel mapping, test-pulse assignment, output load and proof-test sequence before enabling the safety application.
FAQ View All FAQ
-
Which installed system position is intended for X20SC0842?Install X20SC0842 only in the documented B&R X20 safety I/O position and verify the complete catalog marking against the approved hardware list.
-
What signal or controlled function does X20SC0842 handle?Its documented duty is safe digital inputs and 24 v dc safety outputs; the official record lists pulse outputs as 4; 24 V DC.
-
Which companion hardware must be matched to X20SC0842?Match X20SC0842 with X20 safety bus base and 24 V DC safety field circuits, including the documented carrier, cable and project identity.
-
Which electrical value must be verified before wiring X20SC0842?Verify safe low-current outputs: 2 Type B2; 24 V DC; 50 mA. Do not transfer limits from another catalog number.
-
How should the configuration be preserved when replacing X20SC0842?Record the as-found position, conductors, addressing and software revision, then restore only the approved B&R X20 safety I/O configuration.
-
