Siemens 6ES7131-1BL01-0XB0 ET200L Digital Input Read

The Siemens 6ES7131-1BL01-0XB0 ET200L electronic block is a 32-channel digital input module for the ET 200L distributed I/O system, designed to read DC signals from field devices at a 24 VDC supply and to be mounted in a SIMATIC DP ET 200L rack using the TB 32L terminal block. Each of the 32 inputs accepts a DC signal with logic thresholds of -30 to +5 V for a logical "0" and 13 to 30 V for a logical "1," making it compatible with standard 24 V sensors and switches. The module's rated supply is 24 V DC, and it draws approximately 3.2 W of power, with input current specs of up to 70 mA from the supply voltage L+ and up to 100 mA from the load voltage L+ (no-load/load conditions apply). This unit is listed as a spare part for ET 200L and integrates into the SIMATIC DP ecosystem to expand digital input capacity on automation installations. Typical applications include reading digital signals from sensors, pushbuttons, and safety interlocks in manufacturing lines, packaging machinery, and process-control setups where reliable 24 VDC inputs are required.
