Min load: 1 mA @ 5V DC long life.
19 - REMANENCE RELAYSHigh remanence magnetic circuit, allows the relay to latch when the current applied flows through the coil in a direction and unlatches if the current flows in the opposite direction.
Electronic circuitry is added inside the relay, with diodes and precise resistances to control and protect against transitory pulses.
One winding VAC coil and two winding VDC coil.
All coils withstand permanent connection for operation on release the coils needs 50ms minimum pulse and nominal voltage relay operation.
18 - OVERCHARGE RELAYSTwo open contacts, one silver and the other tungsten acting in parallel, separated each other, tungsten contact connect and disconnect, while silver keeps switched.
This relay is used to switch fluorescent and incandescent lamps.
As well as VDC inductive loads.

Contact Isolation NO: 2000 Vrms.
Max load:
16A @ 230V AC1
1.2A @ 110V DC1
0.4A @ 220V DC1
16 - MAGNETIC BLOW OUT RELAYThese versions are similar to 15 types, however they have the addition of a powerful magnet which “blows out” the arc generated when the contacts are opened, therefore quenching the arcing quickly and increasing the contact life.
Avoiding priming and contact welding.
Max Load:
10A @ 220V DC1
2A @ 220V DC13
Model specifications for each model refers to typical values of “new” Relays at 20 ºC complying with EN 60947.
Electrical life tables and maximum VDC current show the typical result of exhaustive tests performed at ambient temperature (20ºC) and 1200 operations / hour frequency and under permanent connection.
Measured values can slightly differ from working conditions.
A maximum over-voltage of 110% Un is permissible at the coil, with rated current through the contacts at an ambient temperature of 60° C.
RelayGo offers collaboration to effectively and efficiently support specific requirements and applications, as well as develop new specifications and non-standard models.
