CARLO GAVAZZI RB2425LA06 Datasheet
Below you will find brief information for Solid State Relays RA 24 10 -D 06, Solid State Relays RA 24 25 -D 06, Solid State Relays RA 24 50 -D 06, Solid State Relays RA 24 90 -D 06, Solid State Relays RA 24 10 LA 06. These relays are designed for use in applications where high surge conditions are expected, such as resistive, inductive, and capacitive loads. They switch on and off when the sine curve crosses zero, which reduces noise and wear on the relay. The relays have multiple features, including direct copper bonding technology for efficient heat transfer. They come in various rated operational voltages and currents. The datasheet also covers thermal characteristics and provides guidance on selecting the right heatsink for optimal operation.

Product Description
The zero switching relay with antiparallel thyristor output is the most widely used industrial SSR due to its multiple application possibilities. The relay can be used for resistive, inductive and capacitive loads. The zero switching relay switches ON when the sine curve just crosses zero and switches OFF when the current crosses zero.

Applications
This relay is designed for use in applications in which it is exposed to high surge conditions. Care must be taken to ensure proper heatsinking when the relay is to be used at high sustained currents. Adequate electrical connection between relay terminals and cable must be ensured.
Thermal characteristics
The thermal design of Solid
State Relays is very important. It is essential that the user makes sure that cooling is adequate and that the maximum junction temperature of the relay is not exceeded.
If the heatsink is placed in a small closed room, control panel or the like, the power dissipation can cause the ambient temperature to rise.
The heatsink is to be calculated on the basis of the ambient temperature and the increase in temperature.
Heat flow
Direct bonding
In the design of the output power semiconductor direct bonding of the copper layer and the ceramic substrate has been applied. This is to ensure uninhibited heat transfer and high thermal fatigue strength.
The relay has been designed for applications requiring large numbers of load cycles.
Power dissipation
The power dissipation for intermittent use is calculated according to the following formula:
I rms
=
I
ON
2 x t
ON t
ON
+ t
OFF
Ex: RA 24 50 -D 06:
Load current = 45 A t t
ON
= 30 s
OFF
= 15 s
I rms
=
45 2 x 30
