Park Relay Performance Test Rig

The Park Relay Test Rig consists of a diode, two capacitors, park relay coil and the relay contacts. The test rig tests the diode drop by applying a constant current across the terminals and measuring the drop across the diode terminals.

Tests the Capacitors by forming a tank circuit.

Tests the coil resistance by applying a constant current across the terminals and measuring the drop across the same.

Tests the contact resistance of the relay by enabling the relay and allowing a constant current to flow through the contacts and measuring the drop across the same.
