The Allen-Bradley 1794-OW8 is a robust relay output module designed as part of the Flex I/O family, featuring eight isolated normally open electromechanical relays. These relays are rated for up to 250V AC and 2A for resistive loads, ensuring reliable performance with a high switching capacity of up to 1800V A Make and 180V A Break at 120/240V AC. This module seamlessly integrates with several terminal base units, such as the 1794-TB3 and 1794-TB2, supporting a signal delay of 10 ms and an enduring mechanical life of 100,000 operations. It operates efficiently with a current draw of 35 mA at 5V DC and requires a supply voltage of 24V DC. Enhanced by eight status indicators, the 1794-OW8 guarantees precise operation and reliable monitoring within a compact form factor of 1.8 x 3.7 x 2.1 inches.
