Product Description
Ordering Key RAM 1 A 60 D 125 Z
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 Relay
with DC control input can be Number of poles
used for phase angle control. Switching mode
The built-in snubber secures Rated operational voltage
transient protection. The LED Control voltage
indicates the status of the Rated operational current
control input. The clip-on cov- Options
er secures touch protection
(IP 20). Protected output ter-
minals can handle cables up
to 16 mm2.
