Honeywell 2643 , Inc. Heavy Duty Switching Relay, 24 Vac, SPDT

SPDT 16AMP RELAY,24V,DBL QC ON COIL

The 2643 is a Micro Switch 16 amp, 24 Vac General Purpose SPDT Relay with quick connect terminal block and screw terminals. The 2643 features a double quick-connect terminal block that is excellent for connecting one or two cable entries without having to solder or crimp on quick-connects. Each terminal accepts wire sizes ranging from 22 to 12 awg with a maximum of 6 conductor per lug.

The Honeywell 2643 Heavy Duty Switching Relay is designed for critical control applications. It has features such as rated voltage of 24VAC; rated current of 16A.; SPDT double changeover (on) coil. This product will add safety and provide secure operation to your alarm system.

The 2643 is a Heavy Duty SPDT 24 Vac switching relay designed for a wide range of general purpose switching applications in industrial and commercial lighting, protective and control circuit switching. The 2643 is housed in a metal enclosure.

The Honeywell 2643 Heavy Duty Switching Relay has 20 contact relays to provide more switching options. It features a double-coil 16 amp relay that can be either single or double-pole. The 2643 has 2 N.C. contacts and 6 normally closed contacts. This means it can close an electrical circuit in two ways that includes both negative and positive current.

The 2643 Heavy Duty Switching Relay can be used as an alternative to a kickback solenoid. It is used in uncontrolled and simple machine control applications for starting, stopping or direction of heavy motors or solenoids. The 2643 Heavy Duty Switching Relay can be daisy chained with other 2643s for additional switching capability. Control currents are limited to 16A on this relay. Requires 24VDC coil power which is to be connected across the coil terminals A1 and A2, input terminals B+ and B-, and output terminals D+ and D-. The red terminal marked with two gold

The 2643 relay is used where a transfer from a relatively low-power control circuit to a higher current power circuit is needed. The relay contacts can be used to provide on-off switching of an air conditioner, fans, lamps or other electrical devices. This relay is also used in contactor applications when a source of definite duration of energization is required and the source cannot be easily turned off by the operator

The HONEYWELL 2643 Heavy Duty Relay is designed as a double-pole double-throw. It can perform switching and direction functions while maintaining consistent 24 Volts of direct current (DC) power. The cam operates on DC voltages from 5 to 28 volts. For use in applications requiring higher switching amperage, this relay may be used in conjunction with the HY264X1 series of .
