Applications
- Digital output control: The module controls digital inputs and provides digital output signals with a rated output current of 0.5 A for signal "1".
- Redundant load control: Two outputs can be switched in parallel for redundant control of a load, using only outputs of the same group.
Key Features
- 32 isolated digital outputs: The SM 322 provides 32 digital outputs with potential separation between channels in groups of 8 and between the channels and backplane bus by optocoupler.
- 24 V DC output supply: Rated load voltage is 24 V, with a permissible range of 20.4 V to 28.8 V. Rated output current for signal "1" is 0.5 A.
- Output protection and timing: Outputs have electronic short-circuit protection. Maximum output delay is 100 μs from "0" to "1" and 500 μs from "1" to "0" with a resistive load.
- Group current limits: Total current is maximum 4 A per group for horizontal installation up to 40 °C, 3 A per group for horizontal installation up to 60 °C, and 2 A per group for vertical installation up to 40 °C.
- Connection and dimensions: The module requires a 40-pin front connector and measures 40 mm wide, 125 mm high, and 120 mm deep. Weight is approximately 260 g.
- Channel status indication: A green digital output status indicator is provided per channel. Diagnostic function, diagnostic alarms, wire-break diagnosis, and short-circuit diagnosis are not available.
