About 1791-IOVW
The Allen-Bradley 1791-IOVW Block I/O Module is a 64-channel I/O module that uses sourcing inputs and sinking outputs for monitoring remotely connected external input and output devices. The 1791-IOVW Block I/O Module, like most 1791 Block I/O modules, requires an external DC power supply that is capable of supplying 18 to 26.4 Volts DC voltage and 100 milliamps of current. The 1791-IOVW Block I/O Module has 2 DIP switches for the configuration of the I/O and setting the rack address. The 1791-IOVW Block I/O Module supports an external DC power supply. The external DC power source supplies the required 18 to 26.4 Volts DC voltage and 100 milliamps of current at 2.0 Amps of surge current for 10.0 milliseconds duration.
The 1791-IOVW Block I/O Module has 32 non-isolated sourcing inputs grouped in 2 groups of 16 inputs each. Each input group is electrically isolated from the next group and they have a combined current rating of 2.4 Volts DC. Every input channel has an on-state voltage range of 12.0 to 26.4 Volts DC and typical on-state current rating of 5.5 milliamps at 24 Volts DC input voltage. The 1791-IOVW Block I/O Module has a maximum impedance rating of 3.4 Kiloohms per channel and maximum signal delay duration of 1.0 millisecond from off to on. The 1791-IOVW Block I/O Module has 32 sourcing outputs arranged in 2 groups of 16 output circuits each. Each output group is individually isolated from the other and they are fused to provide short-circuit protection. The 1791-IOVW Block I/O Module has an on-state output voltage range of 18 to 34 Volts DC at 30 milliamps of maximum resistive output load. It has a maximum output current rating of 2.4 Amps (continuous) per group and a maximum surge rating of 1.0 Amp per output point.
The Allen-Bradley 1791-IOVW DC Block I/O Module is a 64-point I/O block module designed to control and monitor external devices that are connected on the remote I/O link. This module has 32 sourcing inputs and 32 sinking outputs.
