The on-state current is a minimum of 2.5 milliamps at 10 Volts DC and a maximum of 11 milliamps at 30 Volts DC and off-state current is a minimum of 1.5 Amps. The external power of this module is 19.2-30 Volts DC for the voltage and 300 milliamps for the current. The maximum power dissipation is 14.5 Watts and the maximum thermal dissipation is 49.4 BTU/hour. It has an isolation of 500 Volts AC for the power supply to remote I/O, I/O group-to-group, and I/O group-to-logic. The module has an operating temperature of 0-60 degrees Celsius, a storage temperature of 40-85 degrees Celsius, and a non-condensing relative humidity of 5-95%.

The entire 1791-24BR module measures 6.95 x 4.35 x 3.85 inches. These modules are small and self-sustained remote I/O devices, having their own input/output connections, programmable controller interface, signal conditioning circuitry, and power supplies. Compatible controllers are PLC-2, PLC-3, PLC-5/250 and PLC-5 family programmable controllers and SLC 5/02 modular controllers. Its status indicators allow you to monitor communication and input/output states. Terminal strips on the left and right sides are for remote I/O link, input/output connections, and power. The module's two switch assemblies let you configure the I/O rack number, communication rate, starting I/O group, last state, and the last chassis.

Good for a quick backdrop
This works well for what I needed – a simple background for my kids’ online school. It’s lightweight and very easy to put together, and it stands up fine without needing to mount anything. The color is listed as black, but it’s more of a dark gray in person. Not a huge deal, just something to be aware of. It’s not super heavy duty, but it does the job for privacy and as a video backdrop. Overall, a good, portable divider that’s quick to set up and works well for light use.

Hard to assemble
Color: Grey
This is extremely hard to put together, but once its together it is pretty good. You will need to secure it to something. It falls over.
