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

ing and to full sine wave (near
linear). The relay switches off
every time the current crosses
zero, and switches ON in ac-
cordance with the applied
control current.
