Control Circuit Features
ƒ Control Circuit
Standard: Plug-in, socket mounted with dual alarm/trip epoxy sealed
relays.
Optional: Rack-mount confi guration (card cage or enclosure not
included)
ƒ Output Signal
Analog DC voltage related to fl ow or level / interface signal and
proportional to temperature, standard.
ƒ Input Power
Field selected or pre-confi gured in the factory to 115 Vac (±15),
230 Vac (±30, 50 to 60 Hz), 24 Vdc (+4, -3) or 24 Vac (+2, -6);
100 Vac ±10 optionally available. LED indicates power on.
ƒ Power Consumption
AC units, 13 VA maximum; DC units, 7 watts maximum.
ƒ Heater Power
Field or factory selected to optimize switching performance and
rangeability and selectable for specifi c fl uid service requirements.
7 watts power consumption, 230 mA maximum.
Typical Service Sensing Element Power (W)
Gas or Air S-Style 0.75
F-Style 0.25
Liquids S-Style 3.0
The above typical service power selections are for reference
only. Depending on application requirements, surface temperature
rating requirements, and rangeability expectations, alternate power
selections may be recommended. Other intermediate power selec-
tions can be made. Consult installation manual for recommendations
in your service.
ƒ Relay Rating
Dual SPDT or single DPDT fi eld confi gurable 6 amp resistive at 115
Vac, 240 Vac or 24 Vdc; hermetically sealed relay confi gurations
optionally available.
ƒ Electrical Enclosure
Aluminum (epoxy coated) or optional stainless steel. Enclosures are
rated for hazardous location use (Class I and II, Division 1 and 2,
Group B, C, D, E, F and G; and EEx d IIC) and resists the effect of
weather and corrosion (NEMA and CSA Type 4X and equivalent to
IP66).
