I Fixed delay on operate, fixed delay on release, adjustable delay on operate & adjustable delay on release. I Meets or exceeds electrostatic discharge MIL-STD-1686 Class Non-Sensitive. I Welded hermetically sealed enclosure occupies about 1 in3 (16.4 cm3). I 10A, 2 form C (DPDT) output contacts. TD2 series time delay relays are available for delay on operate or delay on release operation. Either can be supplied as fixed or resistor adjustable types. Both military and commercial versions are offered. These products consist of solid state timing circuits controlling our FCA-210 series relays, providing 2 Form C (DPDT) output contacts rated 10 amps. The internal timing circuit uses an 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. follows and connecting it externallly to terminals 1D - 3D as below. REXT = [(T1 / T0) -1] 100K Ohms T0 = Minimum time of selected decade in seconds. 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. The required delay is obtained by calculating the oscillator timing resistor as T1 = Required time delay. EXAMPLE Selected Range = 3-30 sec Required Time = 15 sec REXT = [(15/3) -1] 100K = 400K Timing Action and Terminal Wiring Delay On Operate: The time delay starts on the application of input voltage to X1-X2. The timing circuit energizes the relay at the end of the time delay period. INPUT VOLTAGE INPUT OFF +X1 / -X2 OUTPUT RELAY DEENERGIZED 20-30VDC Delay On Release: The input voltage is continuous to X1-X2. When the control voltage is applied to C1-X2 the timing circuit and the relay are both energized. The time delay relay starts when the control voltage is shut off.

The accuracy requirement applies to any combination of operating temperature and voltage. Add 10ms for timing less than one second. 2. Recycle time to assure that the next timing cycle will be completed. Units can be recycled during timing and after time-out: Delay on operate models - Power must be OFF the input at least 10 ms. Delay on release models - Power must be ON the control terminal at least 10 ms. 3. Transient specifications are based on a maximum duty cycle of 1/50. 4. All wired terminals must be connected together during this test. Dielectric withstanding voltage and insulation resistance are measured between all mutually insulated wired terminals and between all these terminals and case. 2 Catalog 9-1773447-6 Revised 03-2008 www.tycoelectronics.com Dimensions are in inches and millimeters unless otherwise specified.
