FW Murphy 45700003 TR1762 Transformer Relay with Time Delay Lockout

FW Murphy, 45700003, TR1762 Transformer Relay with Adjustable Time Delay Lockout

Features:

• 24 VAC low voltage secondary control circuit with terminals for remote auxiliary switches.
• Plug-in relays have three SPDT silver cadmium oxide contacts providing long life reliability.
• Power relay has extra heavy silver cadmium oxide contacts rated 10 amp, 480 VAC.
• When TR is used with a Murphy Analog Swichgage, it allows for visual reading of operating conditions and provides an adjustable differential between high and low settings throughout the Swichgage dial range.

TR1762 - Same as TR1761 with adjustable time delay lockout of shutdown, for up to 10 minutes, during start-up.

The Murphy TR Series Transformer Relay Assemblies are electric motor controllers.

Murphy Swichgage® instruments for pressure, temperature, level etc., can be used with the TRs for semiautomatic or totally unattended operation and control of your electric motor powered equipment. A set of normally open, dry relay contacts controlled by a 24 VAC relay coil controls the magnetic motor starter holding coil up to 480 volts. The high voltage contacts are completely isolated from the low voltage control to help reduce electrical hazards.

Application:

• The TR Series transformer relay assemblies are ideal for controlling a variety of electric motor driven applications. They are recommended for use on saltwater disposal systems, waterflood systems and many others. Model TR-1762 used in conjunction with model OPLHC Tank Level Controller and an OPLC Series discharge pressure can completely automate a salt water disposal pump.
