Product information
Overview
Applications
- Digital input control: The digital outputs can control a digital input.
- Redundant load control: Parallel switching of two outputs is supported for redundant control of a load.
Key Features
- 8 isolated digital outputs: The SM 322 module has 8 digital outputs with potential separation between channels and the backplane bus by optocoupler.
- AC load voltage: Rated load voltage is 230 V; the stated 120/230 V AC load-voltage range is 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.
- Output protection and diagnostics: Short-circuit protection uses an 8 A, 250 V fuse per group. Diagnostics detect a blown fuse or missing load voltage; fuse blown and missing load voltage are indicated.
- Switching performance: Maximum response time is 300 ms. Switching frequency is up to 10 Hz with resistive load, 0.5 Hz with inductive load, and 1 Hz with lamp load.
- Installation and connection: The module requires a 20-pin front connector and measures 40 mm wide, 125 mm high, and 120 mm deep.
