INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
POINTS OF CAUTION
■
POWER INPUT RATING & OPERATIONAL RANGE
• Power Supply
• Use Clock Generator (model: 20VS5-2).
• When 20VS5-2 is not used, an externally supplied 0 – 15
V square wave, duty cycle 50 % ±5 %, 210 kHz ±5 % clock
can be used.
• Power consumption: Approx. 15 mA DC (no load)
■
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 -10 to +70°C
(14 to 158°F) with relative humidity within 30 to 90% RH
in order to ensure adequate life span and operation.
■
WIRING
• Do not install cables (power supply, input and output)
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.
■
INSTALLING THE MODULE
When it is installed on the printed wiring board, land diam-
eter ø1.5 and through-hole ø0.9 are recommended.
■
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 en-
dure 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.
