SYSTEM SIGNAL PATH

Functional Role & System Integration

SM 523 combines field-state acquisition and actuator switching in one S7-1500 slot. The input side presents sixteen 24 V DC channels, while the output side supplies sixteen 0.5 A channels arranged in two groups. The combined format reduces slot count but requires careful load-group and front-connector checks during replacement.
