RLB1-24DP is a 24Vdc “buffered” relay with a double pole double throw output (DPDT).
Solid-state “buffering” of trigger inputs allow RLB1- 24DP to be connected to equipment with limited current sink ability, enabling control of devices drawing up to 1A per pole.
A constant 24Vdc supply must be connected to the terminals. The relay may be triggered with a negative or positive voltage. 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.
