Finder Time Delay Relays

Time delay relays are used in industrial applications that require time-delayed switching, such as starting a motor or controlling a load. In a standard control relay, contacts close immediately when voltage is applied to a coil, and open immediately when voltage is removed. In some applications, it is desirable to have the operation of the contacts delayed following voltage being applied or removed. On-delay timers begin when voltage is applied. When the time has expired, the contacts close and remain closed until the voltage is removed from the coil. If the voltage is removed before time-out, the time delay resets. When using off-delay timers, nothing happens when voltage is applied. Closing the control input causes the contacts to transfer. Opening the control input causes time to begin and the contacts remain closed. On time-out, the contacts transfer. Closing the control input prior to time-out causes timing to reset. Removing voltage prior to time-out resets the timing and opens the contacts.

Finder 80 Series Modular timers feature 1 contact (16 A). These multi-voltage, single or multi-function devices are compact and suitable for any type of application. 83 Series Modular timers feature 1 or 2 contacts (up to 16 A) with adjustable timing by means of an external potentiometer and have the possibility to operate with both AC and DC voltage. 84 Series Digital Multi-Functional Modular timers feature 2 independent channels (25 functions for each channel to create new functions) and 2 programming modes (via joystick or Smartphone with NFC technology). 85 Series Plug-In Multi-Functional timers feature 2, 3 or 4 changeover contacts (up to 10 A), operate with both AC and DC voltages and are used with 94 Series sockets. 86 Series Timer modules are used in conjunction with socket-mounted relays from the 40, 55, 56 and 62 Series for simple timing applications.
