GENERAL

The MS5D is a plug-in type potentiometer converter that is used in
combination with an instrument to transmit information for displace­ment of valve etc. by resistance change of potentiometer. It converts
the resistance changes into isolated DC current or DC voltage signals.

1. MOUNTING METHOD

NOTE

Plug/disconnect the main unit into/from the socket
vertically to the socket face. Otherwise the terminals may
bend and it may cause bad contact.

1.1 Wall Mounting

Unfasten the upper and lower stoppers of the converter to disconnect
the main unit from the socket. Next, anchor the socket onto the wall
with two M4 screws. Then, plug the main unit into the socket and se­cure the main unit with the upper and lower stoppers.

1.2 DIN Rail Mounting

Locate the converter so that the DIN rail fits into the upper part of the
DIN-rail groove at the rear of the socket, and fasten the socket using
the slide lock at the lower part of the socket.

1.3 Using Ducts

Wiring ducts should be installed at leaset 30 mm away from the top or
bottom of the main unit.

Socket

Note:

• When mounting the units
close together, leave a space
of at least 5 mm between
them.

• Use the supplied spacer to
keep a space of 5 mm for
DIN rail mounting.

2. INSTALLATION LOCATIONS

● Avoid the following environments for installation locations:
Areas with vibration, corrosive gases, dust, water, oil, solvents, di­rect sunlight, radiation, a strong electric field, and/or a strong
magnetic field
Installation altitude: 2000 m or less above sea level.

● If there is any risk of a surge being induced into the power line
and/or signal lines due to lightning or other factors, a dedicated
lightning arrester should be used as protection for both this con­verter and a field-installed device.

● Operating temperature/humidity range: 0 to 50C/5 to 90%RH (no
condensation)

3. EXTERNAL WIRING

WARNING

To avoid the risk of an electric shock, turn off the power
supply and use a tester or similar device to ensure that no
power is supplied to a cable to be connected, before carring
out wiring work.

Wires are connected to the terminals of the converter’s socket. M3.5
screw terminals are provided for the connection of external signals. At­tach a crimp-on lug to each wire for connection to the terminals.

● Recommended cables: A nominal cross-sectional area of 0.5 mm
or thicker for signal cables, and that of 1.25 mm2 or thicker for
power cables.

IMPORTANT

●

The power line and input/output signal lines should be
installed away from noise-generating sources. Other
wise accuracy cannot be guaranteed.

●

The grounding resistance must be 100 Ω (JIS Class D
grounding). The length and thickness of the grounding
cable should be as short and thick as possible. Directly
connect the lead from the ground terminal (terminal no.

9) of the product to the ground. Do not carry out daisy­chained inter-ground terminal wiring.

●

Use of the product ignoring the specifications may
cause overheating or damage. Before turning on the
power, ensure the following:
(a) Power supply voltage and input signal value applied

to the product should meet the required
specifications.

(b) The external wiring to the terminals and wiring to

ground are as specifications.

●

Do not operate the product in the presence of
flammable or explosive gases or vapors. To do so is
highly dangerous.

●

The product is sensitive to static electricity; exercise
care in operating it. Before you operate the product,
touch a nearby metal part to discharge static electricity.
