S20S Module

S20S is an open frame amplifier mountable on a standard DIN rail. It provides 20 optocoupled digital power outputs.

It can drive contactors coils, and solenoids of hydraulic, or pneumatic valves.

3 groups of spring-cage connectors are provided:

  • 2 points for module 24 V power source.
  • 50 points distributed on 2 planes, grouped in 5 independent subgroups of 10 points. Each subgroup has 5 couples of points: 4 for channels output and 1 (the central one) for the power source. Each subgroup is galvanically independent from the others.
  • 1 female DB-25 connector is available for input signals.

Every device has 2 connectors available to directly connect without any extra connector.
