Relay Module, 8 x 20A, 120/277VAC

The application program “20 A8 Binary with status 900701” is used for carrying out the switch functions of the 8-fold load switch N 512.

By assigning parameters, it is possible to define whether all 8 channels are controlled independently or whether 3 channels or 2 times 3 channels are combined and controlled simultaneously by the application program.

Each channel has a communication object available for switching, status interrogation and logic operations. It is also possible to assign the following parameters for each
channel:

• Logic operation
• Starting value of switching object / logic operation on bus voltage recovery
• On delay
• Off delay
• Relay mode: normally open/normally closed contact
• Operating mode: normal mode/time switch
• Behaviour on bus voltage failure (independent of the logic object)
• Send status object: read only / on change in object value

All the above parameters are available for a group of 3 channels (channels A,B,C and/or channels E,F,G) for carrying out applications that require simultaneous
switching.

• Maximum number of group addresses: 52
  
• Maximum number of associations: 52
