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 .21 SLOT 4 PLACES SPECIFICATIONS Input Voltage: 110 to 600 VAC 50/60 Hz Power Consumption: 9 Volt-Amperes Max. Contact Rating: 25 Amps Resistive at 120, 240, or 480 VAC 1 HP Single Phase at 120 or 240 VAC Heavy Duty Pilot 120 to 600 VAC 2 Amps Resistive at 120 VDC 10 Amps Resistive at 48 VDC Ambient Temperatures: -20° F to 150° F -28.8° C to 65.5° C Coil Insulation: Class "B" Output Contact Arrangement: Available in 1, 2, and 3 pole N.O. and/or N.C. configurations as shown in diagram.

PRIMARY COIL The primary coil voltage should be chosen to match the Line Voltage of the control system. The 1500 Series Induction Relay can be supplied with the following line voltages. 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. Maximum distance limitations for typical induction relay secondary circuits are: 12 secondary = 36,000 feet 90 secondary = 12,000 feet 480...
