power contact and twin signal contact 21 - POWER CONTACT AND TWIN CONTACT SIGNAL RELAY

In one single relay we combine the power of a standard unit (10) and the twin contact reliability (17).
Specifically designed for feedback applications requirements.

solid state relay RS - SOLID STATE RELAY

Switching electronic relay, speed and long life (non mechanical parts).
Different models for different applications, AC current (VAC) and DC current (VDC).

twin contacts 17 - TWIN CONTACT RELAYS

Low currents switching applications.
High operational reliability Change-over contacts.
Contact Isolation NO/NC: 1000 Vrms.
Distance between contacts (gap): 0,5 mm.
Gold contacts flash 0,2µ Au or 10µ Au (optional).
Max load: 6 A @ 230V AC1
Min load: 1 mA @ 5V DC long life.

Remanence relays 19 - REMANENCE RELAYS

High 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.

overcharge relays 18 - OVERCHARGE RELAYS

Two 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.
Only available in RQ2.
Max Load:
6A @ 230V AC5a/b (Lamps)
10A @ 230V AC15
1,5A @ 110V DC1

Railway relays RR - RAILWAYS RELAY

Designed to satisfy the most demanding Railway needs, extensive voltage range, vibration and crash requirements.

open contacts 14 - OPEN CONTACTS RELAYS

Separating contacts, increases the distance between contacts (gap) and improves VDC cut.
Gap: 1,5 mm (RQ Series); 1,7 mm (RM and RP Series).
Contact Isolation NO: 2000 Vrms.
Max load:
16A @ 230V AC1
1,2A @ 110V DC1
0,4A @ 220V DC1

magnetic blow out relays 16 - MAGNETIC BLOW OUT RELAY

These 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

SPECIFICATIONS

Model specifications for each model refers to typical values of “new” Relays at 20 ºC complying with EN 60947.

TABLES

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.

OVERVOLTAGE RANGE

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.
