Timer Relays in multiple pole and mounting configurations

Our time delay relays provide enhanced control functionality with the addition of control input circuitry to high performance relays. Our timer relays offer options of hermetically sealed versions and can be qualified for nuclear with pneumatic technology operation. Time delay relays are commonly used in commercial, nuclear, aerospace, and military applications.

Features of the Time Delay Relays

  • Solid state and pneumatic timing circuitry
  • Multiple fixed and adjustable timing functions
  • A choice of mounting style and terminal options: Gold plated pins for socket mounting or tin dipped hook terminals for solder connection, with optional side mounting brackets

  • Available as nuclear qualified control time delay devices with pneumatic technology operation allowing for time delay without power
  • Available as delay-on-operate, delay-on-release in fixed, adjustable and interval timing functions with electromechanical and solid state outputs.

Frequently Asked Questions

Q1: What is a Time Delay Relay?​

A: A time delay relay is an electromechanical relay that can be equipped with programmable electronics that operate the coil at pre-determined or variable intervals.

 


 

Q2: What are the different types of time delay relay and explain them?​

A: There are 3 types of electromechanical time delay relay:

  • Delay on Operate (on-delay): This type delays the activation of the relay after the input is applied.
  • Delay on Release (off-delay): This type delays the deactivation of the relay after the input is removed.
  • Interval (fixed-on period): This type keeps the relay activated for a fixed period once the input is applied.

 


 

Q3: What are some applications of TE’s time delay relays?​

A: TE’s time delay relays are useful for a variety of applications, including:

  • Power load switching
  • Aircraft fuel transfer
  • Cooling/heating devices

 


 

Q4: How does Timer Relay work?​

A: Timer Relay works by activating the selected timer function and delay circuit. When the selected time delay is reached, the relay either energizes or de-energizes based on the timing function, thereby switching the contact positions
accordingly.
