In case of using a 5-port valve as a 3-port valve
The JSY5000 series can be used as normally closed (N.C.) or
normally open (N.O.) 3-port valves by closing one of the
cylinder ports 4(A) or 2(B) with a plug. However, they should
be used with the exhaust ports kept open. Use them when a
double solenoid type 3-port valve is required.
Light/Surge Voltage Suppressor
Light/Surge Voltage Suppressor
M
With power-saving circuit (Made to order)
Power consumption is decreased to approx. 1/4 compared with the
standard product by reducing the wattage required to hold the valve in
an energized state. (Effective energizing time is over 67 ms at 24 VDC.)

· Since the voltage will drop by approx. 0.5 V due to the transistor,
pay attention to the allowable voltage fluctuation. (For details,
refer to the solenoid specifications of each type of valve.)
Residual voltage of the surge voltage suppressor
*
If a varistor or diode surge voltage suppressor is used, there is
some residual voltage to the protection element and rated voltage.
Therefore, refer to the table below and pay attention to the surge
voltage protection on the controller side. Also, since the response
time does change, refer to the response time on page 7.

Caution
If a valve is energized continuously for long periods of time, the rise in
temperature due to heat-up of the coil assembly may cause a decline
in solenoid valve performance, reduce service life, or have adverse
effects on peripheral equipment. If the valve is energized continuously
or if the A side and B side of the dual 3-port valve are energized
simultaneously, be sure to use a valve with power-saving circuit.
Energization of a 2-Position Double Solenoid Valve
Caution
To avoid operation failure, do not energize the A side and B side
of 2-position double solenoid valve at the same time.

Serial transmission type is not applicable for the positive common.
