Key Features
- 16 digital outputs: Digital output SM 322 with 16 DO (solid-state relay).
- 24-48 V AC/DC load voltage: Output supply is specified for 24-48 V AC/DC with rated value (DC) 24 V; 24 / 48.
- Isolated output design: Potential separation is provided between the channels, between the channels and backplane bus, and between the channels and the power supply of the electronics.
- Diagnostics and status indication: Diagnostics function and diagnostic alarm are parameterizable, with diagnostic information readable and LED indication for group error SF (red) and status digital output (green).
Applications
- Digital output switching: Switching 16 digital outputs for connected loads.
- Redundant load control: Parallel switching of two outputs for redundant control of a load.
- Diagnostic monitoring: Reading diagnostic information and using parameterizable diagnostics and diagnostic alarms.
