RLB1-DPDT is a 12Vdc “buffered” relay with a double pole double throw output (DPDT). Solid-state “buffering” of trigger inputs allow RLB1- DPDT to be connected to equipment with limited current sink ability, enabling control of devices drawing up to 1A per pole.
A constant 12Vdc supply must be connected to the terminals marked F & G in Table 1. The relay may be triggered with a negative or positive voltage applied to terminals A or B (respectively).
By default, both poles of the relay are voltage free “dry” contacts. A positive or negative voltage can be applied to the common of either or both poles by changing the jumper settings ( K & L) - Negative to the left or Positive to the right.
