4-20 Remote Control PAS SERIES
• The insulation of the external contact (S) and the
cable connecting it should be greater than the isola-
tion voltage of the unit. For details on the isolation
voltage of each model, see Chapter8 "Specifica-
tions".
• When using shielded wires for connection, protect
the uncovered section of the shielded wire by using
insulation tubes with a withstand voltage greater than
the isolation voltage of the unit.
• The release voltage across pins 10 and 2 is approx. 5 V ± 5 %
maximum, and the short circuit current is approx. 500 µA ±
5 % maximum.
(The internal circuit is pulled up to 5 V through 10 kΩ.)
• When wiring over a great distance, us
e a small
relay and
extend the coil side of that relay.
