How do I select the correct timing relay?

Information required for timing relay selection would include:

  • Timing funtion
  • Timing range
  • Control voltage
  • Mounting requirement

The first thing you should determine is the timing function. Our catalog has a section with timing diagrams and operation summaries. You can use that to determine the timing function (by number) that is needed and then go to the function code cross-reference to determine which timing relays can provide that function.

The Universal TR timers are our most flexible and cost-effective timing relays. They are available with up to seven user-selectable functions and seven user-selectable time ranges. Each unit is DIN rail mountable, eliminating the need for additional sockets. They are available in SPDT and DPDT contact configurations, and have a compact IEC-style footprint and a universal input voltage range for AC and DC applications.
