1771-ODD | Allen-Bradley PLC-5 Digital Output Module, 120V AC, 16-P, Isolated

Description 

The Allen-Bradley 1771-ODD output module is a 16-channel AC output module that is manufactured as part of the PLC 5 series of controller components. Its AC operating voltage range is between 85 and 138 Volts AC and its voltage category rating is 120 Volts AC. The 1771-ODD 16-channel AC output module?s current ratings include 420 milliamps of backplane current, 2 Amps of maximum continuous current per output channel, and 8 Amps of maximum continuous current per module. The 1771-ODD 16-channel AC output module is protected by surge suppression circuitry and it can support fuses.

Technical Specifications 

Information About 1771-ODD

The Allen-Bradley 1771-ODD is a PLC 5 Digital AC Output Module. It is an earlier model of the 1771-OD module with the same specifications. It includes the necessary isolated circuitry to control the on/off status of various user devices such as solenoids and transformers. It is directly controlled by the corresponding bits state in the PLC data table. The 1771-ODD has 16 image bits per module and supports ½, 1, and 2-slot addressing. It contains surge suppression circuitry to suppress high-voltage transients from the AC line.

The 1771-ODD Series A module has 16 isolated outputs with 120V AC voltage category. It has an operating voltage range of 85 – 138V AC and a backplane current load of 420mA. It has maximum continuous current per output of 2A and maximum current per module of 8A. It has a maximum signal delay of 10.6ms from Off to On-state and vice versa. It has a maximum power dissipation of 14.2W and maximum thermal dissipation of 48.5 BTU/hr. It comes with a 1771-WN wiring arm to replace modules, eliminating the need to disconnect wiring. The 1771-ODD is mounted in a 1771 I/O chassis containing a PLC processor with keying bands for correct installation between pins 4-6 for the lower connector and pins 30-32 for the upper connector.

The 1771-ODD module has 32 status indicators at the front of the module. Sixteen indicators on the left show the status of each output and 16 indicators on the right indicate a blown-fuse condition. It also includes optical coupling and filtering for reducing the signal noise.
