When Using a 4 Port Valve as a 3 Port Valve
■
When using a 4 port valve as a 3 port valve
The SJ2000/3000 series can be used as normally closed (N.C.) or
normally open (N.O.) 3 port valves by plugging one of the cylinder
ports 4(A) or 2(B). However, exhaust ports should be left open.
It is convenient when a double solenoid 3 port valve is required.
Light/surge Voltage Suppressor

Non-polar type

Polar type

With power saving circuit
Compared to the standard products, power consumption is
reduced down to approx. 1/3 (in case of SJ3
⃞
60T) by cutting the
unnecessary wattage required to hold the valve in an energized
state. (Effective energizing time is over 67 ms at 24 VDC.)
- When a power saving circuit is installed, a diode to prevent
reverse current is not available for 12 VDC spec. Therefore, use
caution not to connect in reverse.
- Be careful about the allowable voltage fluctuation since a voltage
drop of about 0.5 V occurs due to a transistor. (Refer to the
solenoid specifications of each valve for details.)
Light Indication
When equipped with light/surge voltage suppressor, the light
window turns orange when solenoid A is energized, and it turns
green when solenoid B is energized.
