Allen-Bradley1791-16AC block I/O module.

Allen-Bradley 1791-16AC block I/O module. 

Description For 1791-16AC

The Allen-Bradley 1791-16AC is a block I/O module. This module has Sixteen (16) 120VAC input channels and Sixteen (16) 120VAC outputs. This module comes with a power supply, PLC interface, I/O connections and signal processing and conditioning circuitry. This device is ideally used for implementation of 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.
