Product information
Overview
Key Features
- 32 isolated digital outputs: The SM 322 module has 32 digital outputs with potential separation between channels in groups of 8 and between the outputs and the backplane bus by optocoupler.
- AC load voltage: Rated load voltage is 120 V; the permissible AC range is 79 V to 264 V at 47 Hz to 63 Hz.
- Output current: Signal "1" output current is rated at 1 A. The permissible range is 10 mA to 1 A for 0 to 40 °C and 40 to 60 °C.
- Diagnostics and indicators: Diagnostics detect a blown fuse or missing load voltage. The module has a red group error SF LED and a green digital output status indicator per channel.
- Switching capacity and frequency: Maximum switching capacity on lamp load is 50 W. Maximum switching frequency is 10 Hz with resistive load, 0.5 Hz with inductive load, and 1 Hz on lamp load.
- Mechanical configuration: The module has a double-width design, requires a 20-pin front connector, and measures 80 mm wide, 125 mm high, and 117 mm deep.
