32-channel 24V DC input module for ET 200B
The Siemens 6ES7131-0BL10-0XB0 is a SIMATIC DP electronic module providing 32 digital inputs at 24V DC, designed for the ET 200B distributed I/O system. It communicates via PROFIBUS DP at up to 12 Mbit/s. With a 0.2 ms maximum transition from signal 0 to signal 1, this module captures fast field events — suitable for counting pulses or sensing rapid state changes on a conveyor line.
Input characteristics and wiring
The module accepts 2-wire sensors with a permissible quiescent current up to 1.5 mA. Signal 1 threshold is 13 to 30V, signal 0 is -30 to +5V, with a typical input current of 4 mA at 24V (minimum 2 mA). Wiring options include screw-type and spring-loaded terminals for 3- and 4-wire connections, compatible with TB2/DC, TB2-4/DC, TB4/DC, and TB4-4/DC terminal blocks.
Sourced to order against RFQ through independent distribution.
Physical and environmental fit
Operating range is 0 to 60 °C horizontally (40 °C for other orientations), with humidity limits of 15% to 95% RH per IEC 1131-2. Vibration and shock tested to IEC 60068-2-6 and IEC 60068-2-27.
