2. RLY200 Pinouts and Descriptions
RLY200 is switched and supplied on connector 6; it has one status LED per relay (2 and 3) and one contact connector per relay (4 and 5). Connector 1 is not used. The numbers below are used on every page of the RLY200.
Warning
The relay coils are 12 V coils. Supply 12 V on pin 4 of connector 6, and do not switch more than the contact rating of the relays (1. Introduction).
