POINTS OF CAUTION
■POWER INPUT RATING & OPERATIONAL RANGE
• Locate the power input rating marked on the product and
confirm its operational range as indicated below:
85 – 264V AC rating: 85 − 264V, 47 – 66 Hz, approx. 4 – 6.5VA
24V DC rating: 24V ±10%, approx. 2W
110V DC rating: 85 – 150V, approx. 2W
■GENERAL PRECAUTIONS
• Before you remove the unit from its base socket or mount
it, turn off the power supply and input signal for safety.
■ENVIRONMENT
• Indoor use.
• When heavy dust or metal particles are present in the
air, install the unit inside proper housing with sufficient
ventilation.
• Do not install the unit where it is subjected to continuous
vibration. Do not subject the unit to physical impact.
• Environmental temperature must be within 0 to 50°C
(32 to 122°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■WIRING
• Do not install cables close to noise sources (relay drive
cable, high frequency line, etc.).
• Do not bind these cables together with those in which
noises are present. Do not install them in the same duct.
■AND ....
• The unit is designed to function as soon as power is sup-
plied, however, a warm up for 10 minutes is required for
satisfying complete performance described in the data
sheet.

INSTALLATION
Detach the yellow clamps located at the top and bottom of
the unit for separate the body from the base socket.

Shape and size of the base socket
are slightly different with various
socket types.
■DIN RAIL MOUNTING
Set the base socket so that its
DIN rail adaptor is at the bot-
tom. Hang the upper hook at
the rear side of base socket on
the DIN rail and push in the
lower. When removing the
socket, push down the DIN
rail adaptor utilizing a minus
screwdriver and pull.
■WALL MOUNTING
Refer to “EXTERNAL DI-
MENSIONS.”
TERMINAL CONNECTIONS
Connect the unit as in the diagram below or refer to the connection diagram on the side of the unit.
When an input resistor is provided with the module, attach it together with input wiring to the input screw terminals.

OPERATION DIAGRAM
The diagram below shows an example of I/O characteristics as specified in Table 1.
The split-range operations can be specified when ordering, by using Ordering Information Sheet, or programmed by the user
using PC Configurator Software. Please refer to Users Manual for the PC Configurator for more information.
1) Two pairs of input and output in % define each split I/O range.
Proportional (positive) or inverted (negative) characteristics can be specified.
2) High and low limits for each output can be specified independently within the full-scale range.
3) Fixed output value for each output can be specified independently in advance.
These outputs are provided when the contact input is closed or opened (predefined).
H limit ≥ Fixed output ≥ Low limit
4) Applying the fixed output or not can be specified independently for each output.
In the figure, fixed output is applied to the output 2 with contact input. The solid line shows the function when contact
input is shorted. The chain double-dashed line shows the function when contact input is opened.

CHECKING
1) Terminal wiring: Check that all cables are correctly con-
nected according to the connection diagram.
2) Power input voltage: Check voltage across the terminal
7 – 14 with a multimeter.
3) Input: Check that the input signal is within 0 – 100% of
the full-scale.
4) Output: Check that the load resistance meets the de-
scribed specifications.
5) Split-range setting: Confirm that the transmitter out-
puts are provided as intended.
MAINTENANCE
Regular calibration procedure is explained below:
■CALIBRATION
Warm up the unit for at least 10 minutes. Apply 0%, 25%,
50%, 75% and 100% input signal. Check that the output
signal for the respective input signal remains within accu-
racy described in the data sheet. When the output is out of
tolerance, recalibrate the unit using the PC Configurator
Software (moodel: MFS2CFG).
LIGHTNING SURGE PROTECTION
M-System offers a series of lightning surge protector for
protection against induced lightning surges. Please contact
