Product Description

The industrial, 1-phase relay

with antiparallel thyristor out-

put is the most widely used

industrial SSR due to its mul-

tiple application possibilities.

The relay can be used for

resistive, inductive and

capacitive loads. The zero

switching relay switches ON

when the sinusoidal curve

crosses zero and switches

OFF when the current cross-

es zero. The instant-on relay

Solid State Relays

with DC control input can be

used for phase control. The

built-in varistor secures tran-

sient protection for the heavy

industrial applications, and

the LED indicates the status

of the control input. The clip-

on cover is securing touch

protection to IP 20. Protect-

ed output terminals can han-

dle cables up to 16mm
