The TEKMAR 004 Relay is a 120 V (ac) coil DPDT (double pole double throw) relay used to isolate electrical loads and allow higher current ratings than Tekmar controls' onboard relays. It can double a single output's capability or allow a pump exceeding the control's specified relay rating. The relay has a 120 V (ac) coil that closes 2 normally open contacts and opens 2 normally closed contacts when energized.
This relay is designed to isolate electrical loads and allows higher current ratings than on board relays. It features an LED to indicate when energized and a test tab for easy testing and manual override.
