About 1794-ow8
The Allen-Bradley 1794-OW8 Module is an 8-channel relay output module that is manufactured as part of the Flex I/O 1794 series. It comes with a single group of 8 isolated and normally open electromechanical relays. This module features a Flexbus current of 35 milliamps at 5 Volts DC, and an initial contact resistance of 30 milliohms. Other notable specifications include an approximate weight of 2 kilograms, an isolation voltage of 250 Volts, a power dissipation rating of 5.5 Watts, and an average bounce time of 1.2 milliseconds. The 1794-OW8 output module has 8 yellow status indicators, and it supports fusing of outputs with the use of 3.0 Amps, 250 Volts AC slow-blow fuses. It also features an open-style enclosure, and the installed terminal base determines the terminal screw torque.
The Allen-Bradley 1794-OW8 relay output module has an isolation voltage rating of 250 Volts (continuous), with a basic insulation type for relay to backplane, relay to relay, and relay to power isolation. It also has 50 Volts of continuous isolation voltage with the power to backplane and the basic insulation type. The insulation is type tested at 1500 Volts AC for 1 minute, for relay to relay and for all other combinations. The Allen-Bradley 1794-OW8 relay output module's notable characteristics are an operating shock of 12 g, a non-operating shock of 50 g, and a vibration of 5 g at 10 to 500 Hertz, and it also features an operating temperature ranging from -20 to 55 degrees Celsius and non-operating temperature range of -40 to 85 degrees Celsius. This module also has a relative humidity range of 5 to 95 percent (non-condensing) with a maximum surrounding air temperature of 55 degrees Celsius.
