The ILC TR relay provides a unique solution for remote control and panel mount control applications. Because each relay has its own internal power supply, it can be mounted virtually anywhere without additional transformers or power supplies. By incorporating a unique single moving dual contact design, both endurance and reliability are significantly enhanced. TR relays are magnetically latched, requiring only a momentary rectified pulse to open or close the contacts. Isolated pilot contacts are available for indication of relay status at the switch stations. Available TR-Retro relays automatically turn on upon power-up and require a momentary closure to turn the relay on and off.
