Option 1 (overvoltage protection)

Option 2 (pilot duty switch)

A Solid State Relay family

designed to switch various

loads such as heating ele-

ments, motors and trans-

formers. The relay is capable

of switching high voltages up

to 690 VACrms.

Technique

For higher reliability and load

cycle capability three alter-

nistor chips are soldered di-

rectly 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 in-

clude overvoltage protection

via the varistors and the

possibility of installing a ther-

mostat 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 distribu-

tion system or when motors,

solenoids, valves, lights, heat-

ers or any electrically oper-

ated equipment are con-

nected 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 imped -

ance state when their voltage

threshold is exceeded. Car-

lo Gavazzi SSR's are option-

ally available without varis-

tors if no transient protec-

tion is required.

Output to pilot duty switch ≥4240 V ≥4000 V

Option 2 - Pilot Duty Switch

The RZ relay is available ei-

ther 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 con-

tactor 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. Af-

ter 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 tempe-

rature 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.
