Wiring and zero point / span adjusting of output
current of IP
８
100 type electro-pneumatic positioner
output signal specification (potentiometer built-in)
This product is IP8100 having potentiometer and the P.C.board built in it. It is for
ensuring actuator’s opening by 4
～
20mADC of output signal produced by supplying
power to it.
Supplying power can be set freely between DC12
～
35V.
1.Wiring of input signal , power source and ammeter
Connect input signal(for positioner control) to 1(+) and 2(
－
) of the terminal board.
Connect power source(for detecting output current) to 3(+) and 4(
－
) of the terminal
board.
Connect ammeter in series between (+)side and 3(+) of terminal board or (
－
)side and
4(
－
).
Please refer Fig.1 for wiring.

NOTE
Allowable load resistance in drawing 1 depends on supply voltage
Allowable load resistance is obtained by the formula below.

Normal output current is not be obtained if the load resistance value exceed the result
of formula(1). Please confirm internal resistance when selecting ammeter.
