Internal Circuits and Wiring Examples
Direct Operated 2 Port Solenoid Valve
•
EX510-DYP4
... Output unit for PNP (External power supply type)
Connection to Output Equipment
The output unit can be connected to 2-port solenoid valves such as the VX, VCW, VDW series and other 3-port valves. Pay attention to the applicable cable
and maximum load current for selecting a solenoid valve. The 2-port valves other than shown below can be used as long as they meet the conditions;
operating environment (enclosure, etc.), applicable cable and the
maximum load current. Shown below is the typical 2-port solenoid valve.
Additionally, we recommend a model with surge voltage suppressor is used for the 2-port solenoid valve.
Example) In the case of using 5 VX23 series (rated voltage: 24 VDC/
power consumption: 10.5 W) (calculated under the condition
with 5 valves turned on simultaneously)
Operating current per point for a valve
10.5 (W)
24 (V) =
0.44 (A) ..... Meets the output unit load
current requirement 1.
Therefore, the total current of the output unit is:
10.5 (W)
24 (V) x 5 (pcs.) =
2.2 (A) ..... Only the external
power supply type can meet the
requirement 2. The
internal power supply type cannot be used.
Based on the
requirment 3, The total current for OUT0 to 7
and OUT8 to 15 are
1.5 (A) respectively.
Therefore, 3 VX valves are wired for either 3 points of OUT0 to 7. (
1.32 (A) for OUT0 to 7)
2 VX valves are wired for either 2 points of OUT8 to 15. (
0.88 (A) for OUT8 to 15)
Other outputs can be made available by reducing the total number of the occupied points for simultaneous operation.
