Siemens 6ES7-142-1BD20-1XB0 Programmable Logic Controller Module

Siemens 6ES7-142-1BD20-1XB0 is a Siemens S7 Basic Module in the ET 200X distributed I/O family. The module, identified by 6ES71421BD201XB0, provides four digital outputs (DO) for DC loads and is rated for 24 V DC operation with a maximum of 2 A per output. As a Basic Module in the ET 200X lineup, it can be expanded with analog EM modules to extend its I/O capabilities, and Siemens documents this part as 6ES7 142-1BD20-1XB0 with alternate references such as 6ES71421BD201XB0. Typical applications include controlling discrete loads such as solenoids, relays, and other 24 VDC devices in automation cabinets, production lines, and machine controls seeking compact, scalable I/O expansion. This 4-channel DC output module is designed to integrate with Siemens S7 control systems as part of a distributed I/O architecture, and is listed under the S7 Basic Module family.
