Siemens SIMATIC S7-200 EM223 remote I/O module, model 6ES7223-1BL00-0XA0, adds 16 digital inputs and 16 digital outputs at 24 V DC to a S7-200 PLC. Designed as a remote I/O expansion for S7-21X CPUs, this EM223 module is compatible with S7-21X CPUs only. Each of the 16 input channels accepts 24 V DC signals, while the 16 output channels switch 24 V DC loads, enabling compact expansion of digital I/O in automation projects. As part of the SIMATIC S7-200 family, it provides discrete I/O points for machine control, automation panels, and manufacturing lines.
