Siemens 6ES71511CA001BLO Simatic PLC IO Module

Siemens 6ES71511CA001BLO is an ET 200S Compact digital input module that provides 32 x 24V DC inputs for SIMATIC automation systems. As part of the SIMATIC ET 200S decentralized peripheral family, this module reads binary signals from field devices such as sensors, switches, and proximity detectors and feeds them into a compatible SIMATIC controller. With 32 digital inputs, it offers higher input density in a compact footprint, ideal for applications like manufacturing lines, packaging stations, conveyors, and automated assembly cells where many discrete sensors must be monitored. Catalog listings identify this model as ET 200S COMPACT 32DI STD DC24V 3MS, reflecting its standard 32-channel digital input configuration with DC 24-volt supply. Used within the ET 200S backplane system, it pairs with other ET 200S modules and a compatible PLC to form a distributed I/O network for scalable control architectures.
