(high speed response, 3-port isolation)
BEFORE USE ....
Thank you for choosing M-System. Before use, please check
contents of the package you received as outlined below.
If you have any problems or questions with the product,
please contact M-System’s Sales Office or representatives.
■ PACKAGE INCLUDES:
Amplifier........................................................................ (1)
■ MODEL NO.
Confirm Model No. marking on the product to be exactly
what you ordered.
■ INSTRUCTION MANUAL
This manual describes necessary points of caution when
you use this product, including installation, connection and
basic maintenance procedures.
20VS1A
■ AND ....
•The unit is designed to function as soon as power is supplied, 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 appropriate life duration.
CHECKING
1) Terminal wiring: Check that wiring is correctly connected 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 described specifications.
POINTS OF CAUTION
■ POWER INPUT RATING & OPERATIONAL RANGE
Power Supply
Operational voltage range, power consumption
Operational rating 15V DC ± 5%, 50mA approx. (no load)
■ 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 -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 (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 diameter ø1.6 and through-hole ø0.8 are recommended.

APPLICATION EXAMPLES
The primary amplifier in this unit is high accurate. Installing external resistors to the inverting input (pin 17) and the feedback (pin 16), this unit can be used as a non-inverting or inverting amplifier.
The combined input resistance of the amplifier must be 100kΩ in maximum.
