Siemens 6ES7223-1BH32-0XB0 is a SIMATIC S7-1200 SM 1223 digital input/output module that provides 8 digital inputs and 8 digital outputs for expanding PLC I/O. It operates on 24 V DC with 8 inputs and 8 DO outputs that are transistorized, offering sink/source output configuration and up to 0.5 A per channel, while drawing up to about 145 mA from the 5 V backplane for logic. The module's typical power loss is 2.5 W, and it is designed to integrate with S7-1200 controllers to extend I/O capabilities for automation tasks requiring eight DI and eight DO channels.
