General
a very wide voltage range.
Code-11...-14
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-33 and -34 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-11...-14. 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 d.c. There are two control signals (ON and OFF_N) and a
common reference (COM). For the control signals, the function is guaranteed from 15V d.c. (6mA) to 33V
d.c. (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 d.c. 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 1.5mm2.
