About 1791-24b8
The 1791-24B8 module is a Block I/O module that has been designed to enhance the functioning of programmable logic controllers for PLCs from Allen-Bradley. This module has been included in the Allen-Bradley 1791 series of Block I/O modules. Block I/O modules are single devices that can perform different input and output functions. This module can work as an I/O rack, as a power supply module, and as a series of channels that can be used as inputs and outputs for communication. The Allen-Bradley 1791-24B8 Block I/O module comes with 24 inputs that are arranged in 3 groups of 8 inputs each. These inputs operate with an on-state voltage range of 10 to 30 Volts DC and an on-state current of 2.5 to 11 milliamps.
The Allen-Bradley 1791-24B8 Block I/O module also includes 8 outputs per block that come in a single group. These outputs operate with a voltage range that goes from 10 to 30 Volts DC and with a current rating of 500 milliamps. These outputs operate with a surge current of 3 Amps. The Allen-Bradley 1791-24B8 Block I/O module requires an external power supply rated at 19.2 to 30 Volts DC and a current of 300 milliamps. This module provides a power supply to the RIO isolation, the group to group isolation, and the group to logic isolation that is rated at 500 Volts AC. This module also has a power dissipation rating of 17.1 Watts and a thermal dissipation rating of 58.1 BTU per hour. The recommended conductors for this module are 14 gauge wires that are stranded, and that come with 3/64-inch insulation.
The Allen-Bradley 1791-24B8 Block I/O module has 24 inputs and 8 outputs. This Block I/O module provides isolation between the groups of channels and this isolation is rated at 500 Volts.
