Applications
- Digital output control: Controls digital inputs.
- Redundant load control: Supports redundant control of a load; parallel switching of two outputs is not supported for uprating.
Key Features
- 8 isolated digital outputs: SM 322 provides 8 digital outputs with potential separation between channels and the backplane bus through an optocoupler.
- AC load voltage: Rated load voltage is 230 V; the specified load-voltage range is 120/230 V AC, with a permissible range of 93 V to 264 V at 47 Hz to 63 Hz.
- Output current: Signal "1" output current is 10 mA to 2 A for 0 to 40 °C and 10 mA to 1 A for 40 to 60 °C.
- Protection and diagnostics: Short-circuit protection is provided with an 8 A, 250 V fuse per group. Diagnostics detect a blown fuse or missing load voltage, with PWR, FSG, SF, and digital-output status LEDs.
- Front connection: The required front connector is 20-pin.
- Dimensions and weight: Dimensions are 40 mm wide, 125 mm high, and 120 mm deep; approximate weight is 275 g.
