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.

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 representing 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.

FCB-205 Series, 5 Amperes, DPDT
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:

CII Mid-Range Relays
FCB-405 Series, 5 Amperes, 4PDT
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:

FCA-212 Series, 12 Amperes, DPDT
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:

NOTE: Polarity must be observed with DC coil supply.
Relay is polarized with a permanent magnet and will not
operate or be damaged by reverse polarity.
Diodes used in transient suppression and in AC rectifier
circuits have peak inverse voltage rating of 600 VDC
minimum. Zener diodes have a minimum rating of 1 watt.

NOTE: Polarity must be observed with DC coil supply.
Relay is polarized with a permanent magnet and will not
operate or be damaged by reverse polarity.
Diodes used in transient suppression and in AC rectifier
circuits have peak inverse voltage rating of 600 VDC
minimum. Zener diodes have a minimum rating of 1 watt.

Product Facts

n All
in both states over
that of a spring return
nonpolar design. We also
manufacture other versions
of this relay:
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
