6AG1131-4BD01-2AA0 Siemens Digital Input Module | ET 200SP

Product Description / Overview

The Siemens 6AG1131-4BD01-2AA0 is a SIPLUS ET 200SP digital input module, engineered for distributed I/O systems in industrial automation.
It captures 16 DC 24 V input signals from field devices such as sensors, switches, and pushbuttons, transmitting them reliably to the automation controller.

Designed for harsh environments, the module features a conformal coating and operates in temperatures from -25 … +60 °C.
Moreover, its compact 15 mm width saves cabinet space, and push-in terminals allow fast, tool-free wiring.

This module integrates seamlessly with SIMATIC S7 controllers and TIA Portal, providing high reliability and easy diagnostics via channel-specific LEDs.
Therefore, it is ideal for modern control cabinets where performance, space efficiency, and robust operation are required.
