The Allen-Bradley 1794-OA16 is a robust sixteen-channel digital AC output module engineered for versatility with Flex I/O communication adapters. Designed to operate efficiently within an output voltage range of 74-132 VAC at 47-63 Hz, this module is ideal for handling AC loads such as relay coils, solenoids, and pilot lamps. Its non-isolated channels sustain a maximum output current of 4.0 Amperes, with each channel supporting up to 500 mA under 55 °C, ensuring consistent power delivery with a minimal on-state voltage drop of 1.5V at 0.5 Ampere. The module is built to accommodate quick signal transitions, with maximum power dissipation and thermal dissipation rated at 4.7 W and 16.1 BTU/hr respectively. Featuring a surge current capability of 7 A for 40 ms, repeatable every 8 seconds, and ESD immunity levels up to 8 KV, the 1794-OA16 offers both performance and reliability for demanding industrial applications.
