FUNCTIONAL DESCRIPTION:

12HFA51A42H is a Multicontact Auxiliary Relay Module manufactured and designed by General Electric and used in GE Speedtronic Control Systems. The HFASl relays are instantaneous, hinged-armature, multi-contact, auxiliary relays. They have six (6) electrically separate contact circuits adaptable for either circuit-opening or circuit-closing applications. This arrangement permits several operations to be performed simultaneously. The HFASl relays are available for front or back connection. The front-connected relays are suitable for surface mounting only. The back-connected relays are suitable for either mounting a steel flange is necessary for the latter covers.

CHARACTERISTICS OF MULTI-CONTACT AUXILIARY RELAY MODULE:

  • The HFA51A relay 1s self-reset and has an instantaneous dropout. The HFASlB relay 1s hand reset utilizing a plunger assembly installed through the transparent cover.
  • The HFASlS is similar to the HFASlA except that the (b) contact 1n the No. 3 position is used with an external resistor to obtain a pickup time of 8 milliseconds for high-speed operation. The resistor 1s is hosted by the (b) contact until the relay picks up. When the relay picks up, the (b) contact opens and places the resistor in series with the ·relay coil.
  • Unless relays are ordered with specific contact arrangements, they are shipped with six circuit-closing contacts (Code 60), except HFA51S, which is shipped with Code 01 contacts. Code 01 is available in the HFA51S only. The HFASlS is not available in Codes 51 and 60.
  • The HFASlA, HFASlB, and HFA51P relays are available with coil ratings for standard voltages up to 575 volts at 25, SO, or 60 cycles and up to 250 volts DC inclusive. The HFASlS relay is available in DC voltage ratings up to 250 VDC inclusive.
  • The Type HFA relays should be mounted on a vertical surface. The outline and panel drilling diagrams are shown in Figures 5, 6, and 7. Surface mounting on steel panels requires an insulating bushing for each terminal.

FREQUENTLY ASKED QUESTIONS:

What is a Multi-contact Auxiliary Relay Module?

A Multi-contact Auxiliary Relay Module is an electronic device used in control systems to manage multiple electrical contacts. It allows a single relay to control multiple circuits by providing additional contacts for switching purposes, often used for complex automation or control tasks.

How does a Multi-contact Auxiliary Relay Module work?

This module works by extending the functionality of a primary relay. When the main relay is triggered, the auxiliary relay contacts are activated to control additional outputs or circuits. These modules typically offer multiple NO (Normally Open) or NC (Normally Closed) contacts to suit various applications.

What are the typical applications of a Multi-contact Auxiliary Relay Module?

They are commonly used in industrial automation, control systems, safety circuits, HVAC systems, and electrical panels. These modules allow for better control and integration of multiple devices from a single relay activation.
