SIMATIC S7-200 EM 223 module provides 16 digital inputs and 16 relay outputs for distributed machine control.
Siemens 6ES7223-1PL21-0XA0 is a SIMATIC S7-200 EM 223 expansion module combining 16 digital inputs with 16 relay outputs. The inputs operate from 24 V DC and are arranged in four isolated groups of four. Relay outputs are grouped four by four and support AC or DC loads within the stated ratings. The removable terminal block and compact S7-200 form factor support replacement work where the exact CPU generation, field wiring and load characteristics have been checked.
