Information About 1791-16AC
The 1791-16AC is an Allen-Bradley manufactured Discrete I/O block. This module functions as a complete I/O with built-in functionalities such as Remote I/O adapter mode, communication interface, power supply, Input and output modules. This module is primarily designed for implementing Remote I/O architecture.
The 1791-16AC features an embedded Sixteen (16) Discrete Input channels, with On-state voltage range of 79-132VAC, 47-63 Hz. Each of the embedded input channels exhibit an input signal delay of 1.0 ms for Off to On and 26 ms On to Off transitions. The Sixteen (16) Discrete output channels are in Two (2) groups of 8 with output voltage range of 20-132VAC. The output signal delay is 1.0 ms for Off to On and 8.3 ms @ 60 Hz and 10.0 ms @ 50 Hz for On to Off transition.
The 1791-16AC acts as a Remote I/O adapter. It connects to the main controller through the integrated interface configured as Remote I/O scanner. With Remote I/O protocol, block I/Os, such as the 1791-16AC connects to the communication interface via daisy-chain topology.
Compatible input field devices for use with 1791-16AC are proximity switches, limit switches, selector switches, float switches, pushbutton switches, auxilliary contacts and other binary devices. Compatible output devices include Pilot Lamps, relay coils, horn, buzzer, siren, solenoid actuated devices and other electrical devices.
The 1791-16AC can be mounted in horizontal or vertical orientation. It has a maximum power dissipation of 22.76 Watts and maximum Thermal dissipation of 77.6 BTU/Hr. It has an isolation voltage rating of 500VAC for Power Supply to RIO, 1250VAC for I/O group to I/O group, and 1250VAC for I/O group to Logic.
The output voltage ranges from 20 Volts to 132 Volts AC. Please also check the continuous current necessary for any devices you intend to connect to the 1791-16AC module. There are two types of mounting on this I/O module, vertical and horizontal mounting. The module’s output specifications will vary depending on how you decide to mount this module. A vertical mounting position sustains a higher output current rating because there is more room for air circulation and cooling through the block. With a vertical mounting position, the output current rating is 300 mA at 60 degrees Celsius and 600 mA at 30 degrees Celsius. On horizontal mounting position, the output current rating is 150 mA at 60 degrees Celsius and 300 mA at 30 degrees Celsius.
