6ES7131-4BD01-0AA0 Siemens | 4-Channel Input Module Set of 5

Product Description

The Siemens 6ES7131-4BD01-0AA0 is a digital input module within the SIMATIC ET 200S modular distributed I/O system. Each module provides 4 standard inputs at 24 V DC, designed to connect binary sensors such as pushbuttons, limit switches, and proximity devices. Moreover, its compact 15 mm width allows space-efficient installation on DIN rails, saving valuable cabinet space in industrial automation environments.

Supplied in packs of five modules, this unit ensures cost-effective deployment for larger installations. Clear LED indicators and built-in diagnostics allow fast troubleshooting, while reliable signal acquisition guarantees accurate data integration with SIMATIC S7 controllers through PROFIBUS or PROFINET.
