Siemens 6DL1131-6BH00-0PH1 Digital Input Module

Siemens 6DL1131-6BH00-0PH1 SIMATIC ET 200SP HA digital input module provides 16 x 24 V DC inputs for the ET 200SP HA distributed I/O system. It is designed for use with terminal blocks H1 or M1 and uses color code CC01 with built-in channel diagnostics for each input. The module operates from a 24 V DC supply (nominal 24 V, permissible range 19.2–28.8 V) and includes reverse polarity protection, with a rated current consumption of 60 mA (without sensor supply) and a maximum of 120 mA. It supports I&M data (I&M0–I&M3), is configurable from STEP 7/TIA Portal, and notes firmware version V1.0. Redundancy is supported with the M1 terminal block. Short-circuit protection is electronic (response threshold 0.7–1.3 A; IO redundancy up to 2.6 A). The module’s physical footprint is 22.5 x 115 x 138 mm, and it provides 16 digital input channels suitable for sensing 24 V field devices such as limit switches, proximity sensors, and valve position sensors in automation projects.
