Time-delay Relays, mil-qualified and hermetically sealed

Time Delay RelaysOur range of time delay relays includes delay on operate, fixed and adjustable; delay-on-release, fixed and adjustable; and interval timers with relay or solid state outputs. All are hermetically sealed with a variety of package and mounting configurations. Contact ratings range from 2 to 10A, with MIL qualification on 10A versions. Also available are MIL approved subminiature digital timing modules.

Please contact our specialists for those relays that are no longer readily available, as we can supply custom DSCC approved replacement relays or contactors to suit your requirements.

Mid-Range TD2 series time delay relays are available for delay on operate or delay on release operation, can be supplied as fixed or resistor adjustable types. Both military and commercial versions are offered.

These relays consist of solid state timing circuits controlling the FCA-210 series relays, providing 2 Form C (DPDT) output contacts rated 10 amps. The internal timing circuit uses R/C controlled oscillator with a programmable digital pulse counter, gating a semiconductor switch to operate the relay. Timing is independent of whether the controlling voltage is a ramp or step function.

For the adjustable models, the user specifies a one decade range in seconds, within which the required delay will be set. This range is programmed internally at the time of manufacture.
