Siemens 6ES7 132 4BD02 0AA0 Digital Output Module

The Siemens 6ES7 132-4BD02-0AA0 is a four-channel digital output module for the SIMATIC ET 200S distributed I/O system, providing four DC 24 V outputs designed to switch loads in industrial automation. Each channel is rated for up to 0.5 A, delivering a total module current capacity of 2 A, making it a standard 4 DO DC24V/0.5A device for expanding control of 24 V devices such as relays, contactors, coils, and indicator lamps. As part of the ET 200S family, it integrates into a fieldbus-connected I/O network, enabling reliable remote actuation while reducing wiring complexity in compact control cabinets. The module’s designation—4 DO DC24V—reflects its role in converting PLC logic signals into practical 24 V outputs, and its form factor supports DIN-rail mounting within typical Siemens automation installations. The 6ES7 132-4BD02-0AA0 is used to extend a Siemens automation project with additional 24 V digital outputs, offering scalable, dependable control for a wide range of actuators and simple DC devices in industrial applications.
