Siemens 6ES7132-6BD20-0BA0 Digital Output Module

Siemens SIMATIC ET 200SP digital output module 6ES7132-6BD20-0BA0 provides four 24 V DC outputs rated at 2 A per channel, intended for the ET 200SP distributed I/O system. This DQ 4x24VDC/2A ST module switches field devices such as relays, contactors, lamps, or solenoids from the PLC, and it mounts on the ET 200SP backplane as a compact expansion card. Packaged as a single unit, it uses BU type A0 wiring and carries color code CC02; it also supports module diagnostics to detect faults like short circuits to L+ or M, wire breaks, and supply irregularities, aiding troubleshooting in control cabinets. The 6ES7132-6BD20-0BA0 is part of Siemens’ ET 200SP digital output family and has a documented successor, 6ES7132-6BD21-0BA0, ensuring compatibility with newer backplane revisions. Typical applications include expanding a PLC I/O rack for automation tasks that require four independent 24 V DC loads to be switched from a central controller, such as conveyor sensors, indicator relays, actuators, and other low-power devices in factory automation.
