Siemens SIMATIC 6ES5722-1BB00 | S5 Digital Input 32 Channels

Product Description

The Siemens 6ES5722-1BB00 is a SIMATIC S5 digital input module designed to connect binary sensors to S5 PLC systems efficiently. It provides 32 digital input channels at 24 V DC, enabling reliable acquisition of on/off signals from pushbuttons, limit switches, and proximity sensors.

Moreover, this module supports rack mounting within SIMATIC S5 PLC systems, communicating directly with the CPU via the backplane bus. Its galvanic isolation, group error detection, and clear LED indicators allow fast troubleshooting and reliable operation in industrial environments.

Although the SIMATIC S5 series is a legacy platform, the 6ES5722-1BB00 remains available as a spare part, ensuring continued operational support for manufacturing, process automation, and energy system installations. Its high channel density and compact design make it ideal for medium-to-large automation tasks.
