Datasheet

**RA2A..C** 

## **RA2A..C** 

## **2-pole solid state relays** 

## **Main features** 

- AC switching solid state relay 

- Zero cross switching 

- Back to back thyristor output 

- Direct copper bonding (DCB) technology 

- For resistive AC loads 

- Integrated output overvoltage protection 

- DC control voltage 

- LED for control presence indication for each independent pole 

- 6.35 mm Faston termination for the output terminals and 4-pin header for the control terminals 

## **Description** 

This 2-pole industrial relay minimises the space requirements in a control cabinet without compromising performance. By applying an input voltage on control A, the corresponding output semiconductor is activated at the first zero crossing of line voltage. The same applies to control B. 

LEDs indicate the control status of each pole. The optimised design is free of moulding mass to reduce internal mechanical stress. 

The integrated varistor across the output of each pole ensures protection against overvoltages. 

Specifications are at a surrounding temperature of 25°C unless otherwise specified. 

## **Applications** 

Plastic injection machines, extrusion machines, blow moulding machines, thermoformers, coffee machines, electrical ovens, fryers, shrink tunnels, reflow ovens. 

## **Main functions** 

- 2 independent pole switching solid state relay 

- Zero cross switching 

- Ratings up to 600 VAC, 40 AAC per pole 

- 4.5 - 32 VDC control voltage range

## **Applications** 

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.

## **Heatsink selection** 

Note: Add the currents of both poles and compare with datasheets for proper heatsink. Each pole can handle up to the maximum current specified. Example: Each pole of the RA2A23D40C can handle a maximum of 40 A.

## **Short circuit protection** 

## **Protection Co-ordination, Type 1 vs Type 2:** 

Type 1 protection implies that after a short circuit, the device under test will no longer be in a functioning state. In type 2 coordination the device under test will still be functional after the short circuit. In both cases, however, the short circuit has to be interrupted. The fuse between enclosure and supply shall not open. The door or cover of the enclosure shall not be blown open. There shall be no damage to conductors of terminals and the conductors shall not separate from terminals. Therese shall be no breakage or cracking of insulating bases to the extent that the integrity of the mounting of live parts is impaired. Discharge of parts or any risk of fire shall not occur. 

The product variants listed in the table hereunder are suitable for use on a circuit capable of delivering not more than 65,000A rms Symmetrical Amperes, 600Volts maximum when protected by fuses. Tests at 65,000A were performed with Class J, fast acting: please refer to the table below for maximum allowed ampere rating of the fuse. Use fuses only.

Stock Shortage Specialist

When a component is unavailable, discontinued or has an unacceptable lead time, we tap into our network of vetted European and Asian distributors to source what you need — without compromising on quality or traceability.

Compliant Alternatives

We identify pin-to-pin, electrically equivalent substitutes that meet the same certifications (RoHS, AEC-Q100, REACH) as your original specification — validated against datasheets, not just part numbers. Often at a lower cost.
