The 1791-IOVW is manufactured by the Allen Bradley unit of Rockwell Automation. This I/O module block consists of 32 sourcing inputs and 32 sinking outputs. Many components such as an interface for programmable control, several small I/O devices with self-contained power supplies, signal conditioning circuitry, and input/output connections are present in this block I/O module. In this device, LED indicators are provided for Fuse, Active, Communication, and Power. In addition, another LED array is available for observing the In/Out status. For making the connections, 37 pins are provided on two separate and removable terminal blocks to make connections to the remote I/O. Separately, a terminal block is also provided for connecting the remote I/O link with external power. Also, the device has various configuration switches along with a rack address switch and a termination register switch. These configuration switches could be used to set different settings like baud rate, I/O group, last state, last rack, and processor restart lockout. In the 1791-IOVW, one gets the multi-functionality of an adapter, power supply, I/O module, and I/O rake in one device.
