Solid State Relay Switching mode Rated operational voltage Rated operational current Control voltage Option 1 (overvoltage protection) Option 2 (pilot duty switch)

A Solid State Relay family designed to switch various loads such as heating elements, motors and transformers. The relay is capable of switching high voltages up to 690 VACrms.

Technique

For higher reliability and load cycle capability three alternistor chips are soldered directly on to the direct copper bonded (DCB) substrate. AC-

or DC-controlled versions are available. Built-in LED status indication for applied control voltage. Other features include overvoltage protection via the varistors and the possibility of installing a thermostat for overtemperature protection. When equipped with a pilot duty switch and connected to a mechanical relay a hybrid function is achieved, and it is no longer necessary to use a heatsink.

Thermal Specifications

Option 1 - Overvoltage Protection

Transients are generated by overvoltage of atmospheric origin on the public distribution system or when motors, solenoids, valves, lights, heaters or any electrically operated equipment are connected to or disconnected from the power source. To perform a transient voltage clipping or suppression func-

tion on the AC-load side of an RZ relay, metal oxide varistors (MOV) are normally built in. MOV's assume a low impedance state when their voltage threshold is exceeded. Carlo Gavazzi SSR's are optionally available without varistors if no transient protection is required.

Option 2 - Pilot Duty Switch

The RZ relay is available either with or without pilot duty switch (PDS). Equipped with the PDS and connected to a mechanical relay, a hybrid function is achieved and it is no longer necessary to use a heatsink. The built-in timing function of the relay will ensure that the switching on and switching off is carried out by the Solid State Relay. As soon as the control voltage is applied, the power output turns on and the full voltage is applied to

the load. After max. 10 ms, the PDS will activate the contactor shunting the SSR in about 20 ms. As the load is already under full voltage, the contactor does not take any high inrush currents. It only bypasses the SSR. When the control voltage is removed, the pilot duty switch will first disconnect the contactor. After a delay of min. 30 ms, the load will be switched off. The power outputs will be off max. 100 ms after the input control voltage has been removed.

Heatsink Selection

Compare the value found in the load current versus temperature chart with the standard heatsink values and select the heatsink with the next lower value.

It is recommended to protect the Solid State Relay against overheating. Therefore the chart also states the maximum switching temperature (70, 80 or 90°C) for the optional temperature limit switch.
