4. Wiring
To drive the valve, it must be wired to the power supply and the setting adjuster. Connect the
cable/connector to the connector port of the valve as shown below.
According to the input signal type, determine the cable length with reference to the table below.
Valve Model Number
Input Signal Type
Maximum Cable Length for
Input Signals
ELDFG-*EH-*- D*
±10 V
50 m*
ELDFG-*EH-*- E*
4 - 20 mA
ELDFG-*EH-*- F*
±10 mA
300 m
* If the cable length exceeds 50 m, consult us separately.
4.1 Recommended cable
Depending on the operating environment, use the following standard cable or the equivalent.
JCS 271 "Polyvinyl chloride insulated flexible cords for microphone (shielded)/MVVS"
or the equivalent
JIS C 3306 "Polyvinyl chloride insulated flexible cords (shielded)/VCTF" or the equivalent
JIS C 3401 "Control cables (shielded)/CVVS" or the equivalent
- Finished outside diameter: 8 - 10 mm
- Nominal cross-sectional area:
0.75 - 1 mm
2
(cable length less than 25 m) or 1 mm
2
(cable length of 25 m or more)
Be sure to use the recommended cable or the equivalent for
protection against noise.
Be sure to use a shielded cable, since noise generated with the
solenoid powered on may affect other equipment depending on the
wiring environment.
