To Speak to a sales representative for pricing & lead time:
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.
