1500 SERIES RELAY
DATA SHEET
The Series 1500 Induction Relays provide versatile and economical means of controlling many processing and production functions
from remote locations with the safety inherent in a low energy sensing circuit that is isolated from the AC power source. When installed
near pumps, motors or other operating equipment, the Series 1500 Induction Relay permits use of low-cost light gauge wires for the
control circuit to level sensing electrodes. Relays with low voltage secondary coils provide remote control up to 36,000 feet from
contact type pilot devices. Available as open chassis units or furnished with a choice of standard enclosures, these relays are
connected to a constant source of alternating current. When properly installed, they will draw a maximum of 9 volt-amperes regardless
of the line or electrode circuit voltage.
CAUTION:
Electrodes are terminals of live electrical circuits and must be installed to prevent accidental contact by
personnel. Control power must be disconnected before servicing.
A GOOD DEPENDABLE RETURN GROUND CONNECTION TO LIQUID IS REQUIRED

SECONDARY COIL
Since B/W level control systems use the liquid as an electrical conductor to complete the relay's secondary circuit and
since the resistance or the liquids varies, it is necessary that each induction relay be equipped with a secondary coil that
will operate over the resistance of the liquid it controls. The following tables list the operating characteristics of various
coils available. All values are based on line voltages of 115, 230, 460 or 575 volts at 60 Hertz.

NOTE 1:
The maximum closing resistance in ohms over which each coil will operate is approximately equal to the
specific resistance values shown above. All B/W relays may be energized indefinitely with the secondary
circuit shorted without damaging the coils.
NOTE 2:
Maximum distance limitations for typical induction relay secondary circuits are:
12 secondary = 36,000 feet
90 secondary = 12,000 feet
480 secondary = 250 feet
24 secondary = 30,000 feet
220 secondary = 900 feet
800 secondary = 70 feet
40 secondary = 30,000 feet
360 secondary = 350 feet
