 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

  Operational voltage range: 15V DC ±10%

   Power consumption: Approx. 15 mA DC (no load)

  Install the filter for the power supply as indicated below.

 ENVIRONMENT

• Indoor use
• When heavy dust or metal particles are present in the air, 

install the unit inside proper housing with sufficient ven-
tilation.

• 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.
