RA890F
Flame Safeguard
Primary Control
The RA890F Protectorelay™ Primary Control
is a nonprogramming, amplifying relay that pro-
vides solid state electronic flame safeguard pro-
tection for industrial and commercial gas, oil, or
combination gas-oil burners.
sEmploys rectification principle of electronic flame
detection using a flame rod, rectifying photocell, or
C7012A,C Ultraviolet Flame Detector.
sClipping pilot link jumper wire permits use with
standing pilots.
sCan directly replace RA890E and mount on same
Q270A Subbase.
sSolid state circuitry eliminates vacuum tube replace-
ment and increases resistance to vibration. Power
application not required during Off cycle; no tube to
warm up before starting.
sPush-to-reset safety switch in dust-resistant enclosure.
sBuilt-in protection against ignition crossover in flame
rod systems.
sDoes not start if flame-simulating failure occurs in
flame detector circuit.
sAutomatic safety shutdown if flame fails on start, or
if flame not re-established after flame failure.
sFlame signal current is directly measurable at test
jack.
sLine or 24 volt, automatic or manual controller can be
used. (Manual controller must open circuit on either
power or flame failure.)
sCaptive mounting screws allow easy mounting and
removal. Thermoplastic mounting base.
sOptional alarm circuit indicates safety shutdown.
