Relays
Relays are switches that open and close circuits electromechanically or electronically.   They control one electrical circuit by opening and closing contacts in another circuit.

Relays are generally used to switch smaller currents in a control circuit and do not usually control power consuming devices directly.   Nonetheless, relays can control larger voltages and amperes by having an amplifying effect: a small voltage applied to a relay can result in a large voltage being switched by the contacts.

There a several types of relays that can perform a wide variety of functions in industrial applications: from preventing equipment damage to providing switching capabilities for heavy duty equipment.

RH Series Image

  • Plug-in or Surface Mount
  • In the Event of a Power Failure, Relays Will Return to Their Quiescent State and Continue Sequencing Loads One-at-a-Time
The Alternating Relay is used in multiple-load installations to assure equal run time on all loads. They also allow for the addition of more capacity in the event of excess load requirements. The Alternating Relay provides equal run time on two or more loads by alternating the sequence in which the loads are allowed to start up. In each case, the alternating action is initiated each time the control switch across designated terminals opens. The control switch may be a float, a thermostat, a pressure switch, or a timer contact.
