4 RELAY SHIELD ARDUINO UNO

DESCRIPTION

PRODUCT NAME: FOUR RELAY SHIELD

PRODUCT DESCRIPTION:

           The 4-Channel Relay Module is a full-height module that provides four relay outputs. Any number of 4-Channel Relay Modules can be placed in any of the slots to the right of the Rack Interface Module. Each output of the 4- Channel Relay Module can be independently programmed  to perform needed voting logic. Each relay utilized on the 4-Channel Relay Module  includes "Alarm Drive Logic". The Alarm Drive Logic is  programmed using AND and OR logic, and can utilize  alarming inputs (alerts and dangers) from any monitor  channel or any combination of monitor channels in the  rack. This Alarm Drive Logic is programmed using the 3500  Rack Configuration Software to meet the specific needs of  the application.

Characteristics:

             Normally Closed (NC), Normally Open (NO), and Common (C) relay connections are provided on terminal blocks. When the relay is not energized (digital 0) there is continuity between NC and C. When the relay is energized (digital 1) there is continuity between NO and C.
