Product Description

The RAP-series from Carlo
Gavazzi is a Solid State Relay
family for socket- or PCB­mounting. With built-in LED
status indication for control
input, the relay is an ideal in­terface between PLC’s or
other logic controls and load.
The new housing design and
packing allows automatic in­sertion and soldering.

The relay has been designed
to switch inductive or resistive
loads as long as enough
attention is paid to the speci­fications stated in this data

sheet, e.g. max. current, am­bient temperature etc.

Optotriacs for galvanic sepa­ration together with alternis­tors as output devices give
the most advanced perform­ance. Additional snubbers are
no longer necessary. The zero
switching relay also works
with inductive loads due to its
high surge capability. An inter­nal heatsink optimizes the
thermal resistance between
chip and ambient, thereby in­creasing the lifetime of the
relay.
