TR Relays - Self-Powered Transformer Relay
ILC TR Relays provide a unique solution for remote control applications where panel mount relays are simply not possible. Because each TR120 or TR277 Relay has its own built in Class 2 power supply, TR Relays may be located virtually anywhere without the need of remote mounted transformers or power supplies. Like all ILC relay components, TR Relays are designed and manufactured to be the longest lasting, most reliable relays available. By incorporating a unique single moving part (the contacts) design, both endurance and reliability are significantly enhanced. Compare our 200,000 ON/OFF cycle FULL LOAD and 1,000,000 no load ratings with any other relay in the industry. We're confident you will agree that for reliability and endurance, ILC TR Relays simply can't be beat. TR Relays are magnetically latched, requiring only a momentary rectified AC pulse to open or close the contacts.- Unique patented built-in Class 2 Transformer power supply
