## **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 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 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.
5. Inductive loads must be diode suppressed.

The Series FCB-205 relay is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state . This results in appreciably
increased contact pressure in both states over that of a spring return nonpolar design . We also manufacture other forms of the FCB relay:

The Series FCB-405 relay is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state . This results in appreciably
increased contact pressure in both states over that of a spring return nonpolar design . We also manufacture other versions of this relay:

The Series FCA-212 relay is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state .
This results in appreciably increased contact pressure in both states over that of a spring return nonpolar design . We also manufacture other versions of this relay:

The Series FCA-125 relay is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state .
This results in appreciably increased contact pressure in both states over
that of a spring return nonpolar design . We also manufacture other versions of this relay:

**FCAC-325** — 25 Ampere 3PST-NO Relay with 2 amp SPDT auxiliary

The Series FCAC-325 relay is a polarized single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state . This results in appreciably increased contact pressure
in both states over that of a spring return nonpolar design . We also manufacture other versions of this relay:

The FCA-150 series relay from TE Connectivity (TE) is a polarized, single-side stable design, where the flux from a permanent magnet provides the armature holding force in the deactivated state, and its flux path is switched and combined with the coil flux in the operated state . This results in appreciably increased contact force in both states over that of a spring return non-polarized
design . The FCAC-150 series has a 1 Form C (SPDT) auxiliary contact set rated at 2 A . Designed and built to perform under the most demanding environmental conditions, FCA-150 series relays withstand such changing environmental factors as temperature, altitude, shock, vibration, and salt spray . Minimum mechanical life expectancy is 50,000 cycles under resistive load .

## **Selection and Application Guide**
## **This selection and application guide is suggested practices from ARP (Aerospace Recommended Practice) 4005 Concerning proper performance of relays.**
## **Caution:**
The use of any coil voltage less than the rated coil voltage may compromise the operation of the relay . Choosing the proper relay depends primarily on matching the relay to the load, power supply, and environment . Selection should be limited to items that meet the following requirements:
- **A. Contacts** must be rated for the load. Current rating, type of load (resistive, lamp, motor, inductive, and so forth), impedance range, voltage rating, DC or AC, frequency, single phase or polyphase, polyphase load balance, and type of switching or transfer should all be considered. Each of the following switching and transfer functions places a different requirement on each of the relay contacts and must be considered when selecting a relay with the proper contact rating: (1) On-Off Switching - DC, single phase or polyphase
- (2) Motor Reversing (AC or DC)
- (3) Transferring load between phases of same source
- (4) Transferring load between unsynchronized AC sources
- **B. Power supply characteristics** must be taken into account. Voltage regulation, variations in frequency, ripples and spikes, as well as steady state conditions, should be included. If more than one power supply is involved, not only must each be suitable but interaction between them also should be investigated.
- **C. Coil (or coils)** should be rated so as to have proper operation under all anticipated conditions.
- **D. Consideration of environmental conditions** anticipated throughout the service of life, as well as those expected during storage and transportation before installing the relays in equipment, is mandatory. Electrical parameters, environmental factors, mechanical stresses, and compatibility are among the categories for which the relay must be reviewed.
- **H. Proper transistor control** of the relay coil requires a stable |reference voltage. This can be done by connecting the plus side of the coil to the positive side of the power source, the minus side of the relay coil to the collector of an NPN transistor, the emitter of the transistor to the grounded side of the power source, and the transistor base to the control voltage. For example, see MIL-R-28776/1.
- **I. Any switching device** controlling the relay coil circuit must be capable of withstanding, without damage, the sum of the maximum coil circuitry voltage and the peak value of transient voltage that results when the coil circuit is opened; for example, a switch controlling a relay coil that is supplied with a 28V DC line and subjected to a transient voltage suppressed to 42V must be capable of withstanding 28V + 42V or a 70V surge without damage.
- **J. In selecting solid state electronic switching devices** to control relay coil circuits, care must be used in selecting a solid state device with a leakage current (in the “off state”) that is sufficiently low to permit the relay to drop out.
- **K. Control of the relay coil circuit** by other than step-function switching may invalidate published relay performance properties such as pickup and dropout voltages, pickup, dropout, and bounce times.
- **E. The circuit in which the relay is used,** the interlocking feature employed, the wiring harness, and the associated components should all be reviewed for assuring mutual suitability.
- **F. Relays should be hard wired** whenever possible, to avoid the need for additional contact points associated with the relay plug-in socket arrangement. (Plug-in types should be considered for quick turnaround times).
- **G. To permit “safe” isolation** of relay circuit in the OFF condition, and better eliminate an electrical shock hazard, an electromechanical switching device should be placed between the positive terminal of the power source and relay coil.
