1791R-8V8P

The Allen Bradley 1791R-8V8P is an 8-point DC CompactBlock I/O. The 1791R-8V8P is similar to the 1791R-8B8P. Both have the same type of outputs and inputs, but a different current flow. The 1791R-8V8P has 8 sinking outputs and eight sourcing inputs, making its current flow from output to input, the opposite of that of the 1791R-8B8P. The 1791R-8V8P has many features supporting installations, such as the hardware watchdog function, compact I/O block, and the removable terminations. The hardware watchdog function indicates if the microprocessor fails during installation. The 1791R-8V8P also has a small and compact size, which is cost-effective. Replacing the wiring is easy because the removable terminations are all that need to be changed. No rewiring is necessary. The 1791R-8V8P has 24 volts DC as the nominal input current. The on-state voltage and current input of this module are 10 to 30 volts DC and 2 to 11 milliamps. These specifications apply when the module temperature does not exceed 40 degrees Celsius. This module can deliver power with 10 to 30 volts DC and 1 amp. Check the specifications of the devices before connecting them, and ensure that the devices can function with 1 amp and 10 to 30 volts of DC power.
