Solid State Relays
Industrial, 1-Phase Analog Switching
Type RM1E
•
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
to full sine wave (near linear
power response). The relay
switches off every time the
output current crosses zero,
and switches ON in accord-
ance with the applied control
current.
