Rated operational current

• AC Solid State Relay

• Analog switching (phase-angle control) for resistive

and slightly inductive load applications

• 4 to 20 mA control current

• Rated operational current: 25, 50 and 100 AACrms

• Rated operational voltage: Up to 600 VACrms

• Variable intensity LED-indication according to input

current

• Integral snubber network

Product Description

The analog switching relay works
in accordance with the phase
angle control principle, i.e. the
output switching point in the AC
sine wave depends on the control
current. 4 mA corresponds to no
switching and 20 mA corresponds

Solid State Relays

to full sine wave (near linear
power response). The relay
switches off every time the
output current crosses zero,
and switches ON in accord­ance with the applied control
current.

Applications

This relay is suitable for control of heaters, lighting and
slightly inductive loads such as small fans.
The relay can also be used for soft turn-on of high-power
incandescent lamps.
