Product Description P/N: 1794-OB8
Description
The 1794-OB8 output module is an Allen-Bradley/Rockwell Automation output module from the Flex I/O 1794 series. Its outputs are all sourcing current types of outputs and they are not isolated. The 1794-OB8 output module has been rated for safe operation in both European hazardous locations and North American hazardous locations. The outputs are not fused at the factory, but fusing them for protection during operation is recommended. The 1794-OB8 output module has an operating temperature range from 32 to 131 degrees Fahrenheit.f 2.3 A and Power of 0.75kW (1.0 HP).

Information About 1794-OB8
The Allen-Bradley 1794-OB8 is a 1794 FLEX Digital DC Output Module. It is fitted inside the terminal bus, making a connection with the field devices and the I/O bus. Modules can be inserted or removed under power since the I/O module does not have any direct wiring. It in turn saves time and removes system restarting inefficiency.
The 1794-OB8 module has 8 current sourcing outputs. It has 24V DC nominal On-State output voltage. It has a maximum output delay time of 0.5ms from Off-to-On and 1ms from On-to-Off. It has a maximum power dissipation of 3.3W at 31.2V DC. Terminal Base units compatible with it are the 1794-TB3, 1794-TB3S, and the 1794-TBKD. The 1794-OB8 has an external power supply of 10 - 31.2V DC voltage with a 5% AC ripple and 10 - 35mA current. It is installed using a DIN rail by simply snapping it onto the DIN rail. It has various communication options such as ControlNet, DeviceNet, EtherNet/IP, and Universal Remote I/O.
The 1794-OB8 module has 16 yellow LED status indicators for each channel indicating a corresponding input device and output signal. It also has XT versions of standard modules for operating in extreme environments which reduce panel and maintenance costs. The 1794-OB8 has a 0 - 55 °C (32 - 131 °F) operating temperature and 5 - 95% noncondensing relative humidity.
