Siemens 6ES7133-0BH01-0XB0 Digital Input Output Module

Siemens 6ES7133-0BH01-0XB0 is a SIMATIC ET 200B digital input/output module that provides 8 digital inputs and 8 digital outputs at 24 V DC for distributed I/O in DP networks. This 160 mm-wide ET 200B module mounts to standard terminal blocks and supports a backplane bus speed of 12 Mbit/s, with connections via TB1/DC and TB3/DC terminal blocks (TB1-4/DC, TB3-4/DC) for convenient wiring. The 8 inputs accept DC signals with a 0 level defined as -30 to +5 V and a 1 level defined as 13 to 30 V, drawing typically 4 mA per channel and featuring a 2–3 ms response delay for standard inputs, with unshielded cables up to 100 m. The 8 outputs are 24 V DC and include electronic short-circuit protection, with a maximum of 0.5 A per output and a lamp-load switching capacity of up to 5 W; the module draws about 70 mA from the L3+ supply (up to 500 mA maximum) and can dissipate up to 3.8 W of power in operation. In DP configurations, this module serves as a compact digital I/O expansion for ET 200B systems, enabling reliable binary sensing and control across distributed field devices.
