• Power Supply
Operational voltage range, power consumption:
Rated voltage ±15V DC, approx. 7.5mA DC (no load)
Attach the surge absorber when excessive voltage is ap-
plying to the input side power line +15V, output side pow-
er line +15V, and -15V.

■ ENVIRONMENT
• Indoor use.
• 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 -25 to +85°C
(-13 to +185°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.
■ MOUNTING THE MODULE
• It is recommended to mount the module on a printed wir-
ing board having through-holes of ø0.8 with land diam-
eters of ø1.2.
■ 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.
• With voltage output, do not leave the output terminals
shortcircuited for a long time. The unit is designed to
endure it without breakdown, however, it may shorten ap-
propriate life duration.
CHECKING
1) Terminal wiring: Check that wiring is correctly connect-
ed according to the connection diagram.
2) Power input voltage: Check voltage across the pins.
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.
