Information About 1791-0A16
The Allen-Bradley 1791-OA16 is a Block I/O module featuring sixteen (16) 20-132VAC output channels with a frequency of 47-63 Hz. This module is divided into two (2) groups of eight (8) output channels each, capable of energizing electrical loads such as pilot lamps, buzzers, sirens, relays, contactors, and other devices.
The 1791-OA16 is compatible with legacy PLC-2, PLC-3, PLC-5/20, and PLC-5 Programmable Logic Controllers. It acts as a distributed input and output module, which reduces costs by eliminating long-distance signal cable runs, as it allows installation near the electrical devices. The module's compact form factor also requires minimal panel space.
This module is externally powered, requiring a supply voltage of 85-132VAC at 47-63 Hz and a continuous current supply of 150 mA. It features built-in isolation circuitry, with power supply to RIO isolation rated at 500VAC, I/O group-to-group isolation rated at 1250VAC, and I/O group-to-logic isolation rated at 1250VAC. For signal wire termination, the appropriate conductors are gauge 14 stranded wire with a maximum insulation thickness of 3/64 inches.
The output voltage channels have an ON to OFF transition delay of 8.3 ms at 60 Hz or 10.0 ms at 50 Hz, and an OFF to ON transition delay of 1.0 ms at both 60 Hz and 50 Hz. This module supports both horizontal and vertical mounting. When mounted vertically, it has an output current rating of 300 mA at 60°C and 600 mA at 30°C. When mounted horizontally, it has an output current rating of 150 mA at 60°C and 300 mA at 30°C.
The 1791-OA16 includes a removable terminal strip for convenient signal termination and module replacement. For troubleshooting, it features a status indicator.
The required power supply for the 1791-OA16 is 120 Volts AC. Before connecting the block I/O’s inputs to other devices, verify that the devices meet DC and AC input specifications and check the required continuous current to power up the devices before connecting to the block I/O outputs.
