Output relays
Relays are provided as ‘dry’ contacts or ‘electromagnetically switched’ contacts. Each relay is
rated 3 A at 24 Vdc for a resistive load, or 1 A at 24 Vdc for an inductive load.
The relay is controlled by the assigned output in the SMB Configuration App. To utilize the
relay, terminate the positive constant supply to the common termination of the relay and
nominate either Normally Open (N/O) or Normally Closed (N/C) termination to operate the
external device. Refer to the image below.
