General
100(S)-E and 300(S)-EO contactors are i f tted with an electronic interface. For a given coil, this allows
the cont actor to accept a very wide voltage range.
Code KJ, KD, KN (J, Y, D, B)
Operation is done, as with conventional contactors, by applying and removing supply voltage on A1
and A2. Closing 85% and opening at 55% of the lower nominal voltage limit, which is indicated in the
functional diagram.
Code ED and EN built-in PLC interface
Operation is controlled by separate logic control signals from, for instance, a PLC. Use of logic control
requires a steady supply voltage on A1 and A2 within the rated voltage range, as described for
code KJ, KY, KD and KN (J, Y, D, B). The function of the logic control signal will no longer be guaranteed
when the supply voltage on A1 and A2 is removed.
The logic control signals are operated with 24V DC. There are two control signals (ON and OFF_N) and a
common reference (COM). For the control signals, the function is guaranteed from 15V DC (6mA) to
33V DC (20mA).
The contactor is closed by a control signal ON and opened by removal of control signal from OFF_N. The
functions are described in diagram below. "1" means 24V DC between the control signal and COM. "0"
means no voltage between the control signal and COM. Minimum control signal pulse length for
opening and closing is 10ms. To connect the PLC interface, use cable dimension of max 1.5mm
