External connection

Pressure clamp terminal, KS cable, MIL connector cable

*1:

The withstanding voltage for using MIL connector cable depends on the electrical specifications of its cable.

*2:

When the pulse input signal is dry contact (such as from a mechanical relay) up to 10 Hz, it is possible to eliminate the

chattering.

*3:

The connection method of the field devices varies depending on the input signal.

For details, please refer to “Installation Guidance (TI 33Q01J10-01E).”

*4:

Input frequency is 0 to 800 Hz to receive no-voltage contact signals between terminal B and C.
