About 1791-IOBB
The Allen-Bradley 1791-IOBB Block I/O Module is a 16-point discrete block I/O module that is designed to monitor and control external devices that are connected on the remote I/O link. It is compatible with the Allen-Bradley PLC-5, 2, and 3 controllers, and with the SLC-500 controllers, and it supports discrete block transfers with these controllers. The 1791-IOBB Block I/O Module requires an external DC power supply for operation. This power source supplies 200 milliamps of maximum current at 24 Volts DC, a 10 to 30 Volts DC supply voltage range, and 5.5 Amps of maximum surge rating for 10 milliseconds. The 1791-IOBB Block I/O Module has 10 non-isolated sinking inputs with a 20.5 to 27.6 Volt DC operating voltage range and 6.3 milliamps of minimum load per input channel. Each 1791-IOBB Block I/O Module input has off-state ratings of 5.1 Volts DC/1.0 milliamp and maximum signal delay time of 1.5 milliseconds (ON) and 1.0 millisecond (OFF).
The 1791-IOBB Block I/O Module also has 6 sourcing output circuits with 10 to 30 Volts DC of rated output voltage and 0.5 Amps of maximum output load per output channel. Each output point has 3 Amps of maximum surge rating for 10 milliseconds and off-state ratings of 0.5 milliamps/30 Volts DC. Each 1791-IOBB Block I/O Module output has a maximum turn-on time of 1.5 milliseconds and a turn-off time of 1.0 millisecond. The 1791-IOBB Block I/O Module has a rear-side removable remote I/O connector for connecting to a programmable controller by using a remote I/O cable. The 1791-IOBB Block I/O Module also has a DH-485 port for connecting to the DH-485 network (4000 meters is the maximum cable distance). The 1791-IOBB Block I/O Module has two 6-position DIP switches for configuring the module’s DH-485 terminator, last state, last chassis, baud rates, and starting I/O groups.
The Allen-Bradley 1791-IOBB Block I/O Module is a 16-point discrete block I/O module designed to control external devices connected on the remote I/O link. This module has 10 non-isolated sinking inputs and 6 non-isolated sourcing outputs.
