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.
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
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.
T1 = Required time delay.
EXAMPLE
Selected Range = 3-30 sec
Required Time = 15 sec
REXT = [(15/3) -1] 100K = 400K

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.
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.

NOTES
1. 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.

TD2 Series Time Delay Relay (Continued)
Typical Mil-Spec Part Number TD2 28- 5002 P
Series:
TD2 = Time delay relay with 2 pole, 10A output
Mil-Spec Model:
28 = M83726/28 (Fixed, Delay on Operate)
29 = M83726/29 (Fixed, Delay on Release)
30 = M83726/30 (Adjustable, Delay on Operate)
31 = M83726/31 (Adjustable, Delay on Release)
Time Delay Range (Within 0.1 to 500 seconds):
For /28 and /29 types (fixed types), the delay is expressed in
milliseconds in a four-digit code. The first three digits are significant.
The fourth is the number of zeros following the first three.
Example: 5002 is 50 seconds.
For /30 and /31 types (adjustable types), the delay decade range is
expressed in milliseconds in a four-digit code represesnting the upper
limit of the range. The first three digits are significant. The fourth is the
number of zeros following the first three.
Example: 1001 is 1 second, so the range is 0.1 to 1 second.
