Littelfuse ARP42S Alternating Relay

Littelfuse ARP42S Alternating Relay is an electrical control part that is used to switch between two loads in a control circuit. It operates by the use of an internal relay logic to alternate the output path with each energization of the control signal to enable balanced run time of the connected equipment during operation in pump systems, condensate management units and HVAC systems. The relay is mounted in the control panel where there are low-voltage wiring to the input and output terminals. Switching of control over connected part assists in the equal distribution of operating cycles.
