Applications
- Digital output control: The module controls digital outputs and can control a digital input.
Key Features
- 16 isolated digital outputs: The SM 422 provides 16 digital outputs with potential separation between channels and between the channels and the backplane bus.
- 24 V DC load supply: Rated load voltage is 24 V, with a permissible range of 20.4 V to 28.8 V.
- 2 A rated output current: For signal "1", the rated output current is 2 A, with a permissible range of 5 mA to 2.4 A.
- Electronic short-circuit protection: The digital outputs have clocked electronic short-circuit protection.
- Fast resistive-load response: Output delay with a resistive load is maximum 1 ms for both "0" to "1" and "1" to "0".
- Group current limits: Total output current per group is maximum 3 A up to 40 °C in all mounting positions, or 2 A up to 60 °C for 2 adjacent outputs each.
