PAB02 | P70870-4-0369059 369059A10 ABB Binary Output Module

Relay contacts are used for the binary outputs.The 16 outputs are combined into two groups. Each 8 outputshave a common return. The groups are isolated from one anotheras well as from the internal electronic.The supply voltage for the coils of the relays (24 V DC) is switchedby an internal relay (R17).The supply voltage for the coils of the relays (24 V DC) is monitored internally before and during the command output.The command output to the process equipment can be effectedeither directly or in conjunction with a command output supervision module. The command output supervision module coversthe (1 out of n) check of the output circuits. More details canbe found in the data sheet of the command output monitoringmodule.
