CG900 Series Time Delay Relay Option
|
The
CG900 series is a delay timer available in 19 time ranges from
0.5 seconds to 30 hours. The timer uses CMOS integrated
circuits for the timing function. The desired delay time
is set by the adjustment of a calibrated knob referenced to an
index mark on the housing. At time out, a DPDT relay is
actuated for control of output loads. Available
on Explosion Proof models only, any
style.
The CG900 timer is housed ina molded Noryl Case which provides
high impact resistance and self extinguishing in case of fire
or excessive heat. All external connections are made to
the standard 8-pin octal relay base. An optional hold-down
clamp is available for use with installations requiring horizontal
mounting or exhibiting excessive vibration.
Modular
Time Delay used where operations require an integral unit
with longer delay than the DASH POT before
actuating and completing circuitry. Self-resetting
timer allows delay from 0.5 seconds to 30 hours as required.

Operation: |
The timing base for
the CG900 series timer is established by a precision capacitor
and the adjustable dial potentiometer. The technology utilized
in the CG900 series provides accurate control over extended time
ranges to 30 hours.
Delay time starts upon application of power to the timer input
terminals. At time out, the delay contacts transfer. Reset
occurs whenever power is removed from the control input.
