SIMATIC S7-200 CN EM 223 module combines four digital inputs with four relay outputs for compact control.
Siemens 6ES7223-1HF22-0XA8 is a SIMATIC S7-200 CN EM 223 digital I/O expansion module intended for S7-22X CPUs. It combines four 24 V DC digital inputs with four relay outputs. The compact housing supports small machines that need a limited number of additional sensors and switched loads, while the relay outputs allow suitable AC or DC circuits to be controlled after electrical and inrush ratings are checked.
