A timer relay is a combination of an electromechanical output relay and a control circuit the contacts will open or close before or after a preselected timed interval.
what is an 8 pin relay
the relay works on the principle of electromagnetic force when the coil is energized it becomes magnetized in an 8 pin relay as shown here there are 2 common contacts 2 normally open contacts and 2 normally closed contacts relays control one electrical circuit by opening and closing contacts in another circuit.
Phase Failure Relay (PFR) is a safety device that operates automatically, and is designed to be used for the electrical safety of three-phase machines.
These are used to protect electric motors against faults on the three-phase network, and will detect the loss of a phase, the change in order of the phases, or even a voltage imbalance between the phases.
If any of these events occur, the PFR will remove power from the control circuit, stopping the motor and protecting it from damage.
