Product details

The Siemens 6ES7131-1BL01-0XB0 is a 32-channel digital input module for the ET 200S system, communicating over PROFIBUS DP at up to 1.5 Mbit/s. Rated for 24 V DC inputs, it draws 70 mA from the supply L+ and has a typical power loss of 3.2 W. Input signal delays are 2 to 4.5 ms for both 0→1 and 1→0 transitions.

Panel integration

It uses the TB32L terminal block (order separately) and accepts 2-wire sensors. Unshielded cable runs up to 600 m; shielded up to 1 000 m. Freeze capability and diagnostics are supported, with a BF bus fault LED.
