Siemens 6ES7131-6BH00-0BA0 ET 200SP Input Module

High-Density Input Capture for Modern Distributed I/O

The Siemens 6ES7131-6BH00-0BA0 digital input module provides 16 channels for the ET 200SP distributed I/O system. This module accepts 24V DC signals from sensors, pushbuttons, and switches in industrial automation networks. Each channel features a configurable input delay from 0.05 ms to 20 ms. The module includes integrated diagnostics for wire-break and short-circuit detection per channel. LED indicators on the front panel display the current status of every input. Moreover, the module supports the new ET 200SP base unit design for tool-free wiring.
