About this product
The SM 1223 combines digital inputs and digital outputs in a single expansion module and is the most frequently specified S7-1200 signal module. It is used to extend a compact CPU with additional field devices such as sensors, contactors and solenoid valves without adding a second controller. VeeTech supplies the module and incorporates it into I/O schedules, panel wiring and loop-checked commissioning.
