Siemens 6ES7 132-4HB01-0AB0 Programmable Logic Controller Module

Siemens 6ES7 132-4HB01-0AB0 is a two-channel relay output module designed for the SIMATIC ET 200S distributed I/O system. It provides two relay contacts to switch external circuits and is rated for loads up to 5 A per channel at a load voltage range of 24 to 230 V UC, enabling control of devices such as lights, valves, solenoids, or small motors in industrial automation setups. The module is 15 mm wide and mounts on a standard DIN rail in an ET 200S rack, fitting into SIMATIC DP networks as part of a scalable S7 automation installation. Its order number is 6ES7 132-4HB01-0AB0, identifying this specific module in Siemens catalogs. In typical configurations, the relay outputs are driven by a compatible S7 controller over the ET 200S backplane, enabling discrete on/off control of line-powered devices while maintaining isolation between the controller logic and the switched loads. This module belongs to the 6ES7 family of I/O modules and is intended for use where compact, two-channel relay switching is required within industrial environments.
