Product information
Overview
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 supply: Rated load voltage L+ is 24 V, with a permissible range from 20.4 V to 28.8 V.
- 0.5 A rated output current: Output current for signal "1" is 0.5 A rated, with a permissible maximum of 0.6 A for 0 to 40 °C and 40 to 60 °C.
- Group current capacity: Total output current per group is up to 4 A for horizontal installation at up to 40 °C, 3 A for horizontal installation at up to 60 °C, and 2 A for vertical installation at up to 40 °C.
- Electronic short-circuit protection: The digital outputs have electronic short-circuit protection and a typical response threshold of 1 A.
- 40-pin front connector: A 40-pin front connector is required for connection.
