Siemens 6ES7133-0BN01-0XB0 Industrial PLC IO Module

Siemens 6ES7133-0BN01-0XB0 is a SIMATIC ET 200B digital input/output module that provides 24 digital inputs and 8 digital outputs (a 32-point card) for distributed control, all operating at 24 V DC. Intended for use in ET 200B racks, the module connects to a Siemens PLC (S7-300/400 family) to expand field I/O; it weighs about 0.325 lb, and its width is 235 mm, reflecting a compact, DIN-rail-ready form factor. The module draws approximately 5.5 W and supports fast digital signaling with an input delay around 3 ms, enabling responsive sensing and actuation across 24-V DC devices. Known as 6ES7133-0BN01-0XB0, with the market-facing number 6ES71330BN010XB0, it is used for industrial automation tasks such as sensors, switches, and signaling devices in automation lines.
