2-7. SI-65(A) Power Source
There are two ways to supply power to SI-65/SI-65A.
Supply by AC
1.
Connect the plug of the AC adapter to the DC jack (DC-IN) of SI-65/SI-65A.
2. Plug the AC adapter to an AC outlet to supply power.
Please use appropriate AC adapter which complies with the power specification and safety
standards of the country in which you use SI-65/SI-65A.

VFN-650B
AC 100V ± 15%, 50/60 Hz
PSE
6A-181WP09
AC 90 - 264 V, 50/60 Hz
PSE/UL/CUL/GS/CCC/CE
Note: When using VFN-650B (AC adapter), power consumption of AC is about 4.9VA for SI-65 and
about 3.7VA for SI-65A.
The operating temperature of the VFN-650B is from –10 to +50 degrees Celsius. When using SI-
65A at the temperature of –25 to –10 or +50 to +75 degrees Celsius, please do not use the AC
adapter. Prepare a DC source which is appropriate for the environment.
Supply by terminal block
(In the case of SI-65)
1. Prepare DC source of 5 - 12V (DC 5 - 9V is recommended), 4W or more.
* Current consumption of SI-65 is up to 300mA regardless of supply voltage.
External source of lower voltage is recommended. Because the more voltage is,
the more power consumption and heat tend to be.
2. Connect the 6th pin of the terminal connector with the plus pole of the external
source and connect the 5th pin with the minus pole (GND) of the source.
* Please use a cable of AWG22 - 14. Bare the end of the cable for 6mm, which is
to be connected to the terminal block. Please do not make offset when you use
twisted wire.
(In the case of SI-65A)
1. Prepare DC source of 5 - 30V, 2W or more.
* Current consumption of SI-65A is up to 330mA when DC is 5V, 130mA when
DC is 12V and 60mA when DC is 30V.
2. Connect the 6th pin of the terminal connector with the plus pole of the external
source and connect the 5th pin with the minus pole (GND) of the source.
* Please use a cable of AWG22 - 14. Bare the end of the cable for 6mm, which is
to be connected to the terminal block. Please do not make offset when you use
twisted wire.
