Four relay outputs in a 15 mm slice
The Siemens 6ES7132-6GD50-0BA0 is a digital output module for the ET 200SP distributed I/O system, packing four relay outputs into a 15 mm-wide housing. Each channel switches up to 2 A at 24 VDC coil voltage, with the module rated for 8 A total at 60 °C. The relay type means galvanic isolation between channels and the backplane — a practical choice when you need to separate control logic from field loads like contactors, solenoid valves, or small motors.
Base unit and mounting
This module snaps onto a BU type A0 base unit — the 2-wire connection variant. The mechanical coding element prevents inserting it into the wrong base unit slot.
Diagnostics and status feedback
A green/red DIAG LED reports module diagnostics, and individual channel status shows via green LEDs. Diagnostic alarms are supported, and I&M data (I&M0 to I&M3) is available for asset tracking. The module also reports group error status. Firmware is field-upgradeable (V1.0 as shipped).
