Product information
Overview
Applications
- Digital input control: The outputs can control a digital input.
- Motor starter control: The outputs can control up to 4 NEMA compliant motor starters.
- Lamp-load switching: The outputs support lamp loads up to 50 W.
Key Features
- 16 isolated digital outputs: The SM 322 provides 16 digital outputs with potential separation between channels in groups of 8.
- AC load voltage and output current: Rated load voltage is 230 V; the permissible AC range is 79 V to 264 V. Signal "1" output current is rated at 1 A.
- Output protection: Short-circuit protection is provided with an 8 A, 250 V fuse per group; fuse-blown indication is available.
- Switching performance: Maximum switching frequency is 10 Hz with resistive load and 0.5 Hz with inductive load.
- Diagnostics and isolation: The module has fuse and group-error indications, digital-output status indication, and isolation tested with 4 000 V DC.
- Installation and connection: The module requires a 20-pin front connector and measures 40 mm wide, 125 mm high, and 120 mm deep.
