requirement, please clarify when ordering
Ⅱ. How to use: Refer to connecting diagram
Amplifier and external wiring connection
1. The electrical supply should be D.C.24V
The point 6A or 6C connected to the positive pole of the electrical supply.10A
or 10C connected to the negative pole of the electrical supply.
2. The connection of between the amplifier and solenoid.
The two ports of the proportional solenoid should be connected to 2A
(or 2C) and 4 A (or 4C) separately.
Remark: there is no directionality in the wire connecting.
3. The connection with the bit shift sensor: the amplifier should be
connected to the bit shift sensor with the shield cable.
20c should connect to the port 1 of the bit shift sensor.
14c should connect to the port 2 of the bit shift sensor.
22c should connect to the port ┴ of the bit shift sensor.
4. The input of the control voltage signal
(1). +9V control voltage (command electrical level) input port:
through the external potentiometer (resistance: 5K-10K ) input
the voltage signal 0-+9V voltage signal from 26C.
(2). +10V buffering simulated valve input port: programmable
controller or
functional generator output the differential voltage should be input
from port 22A and 24C. 22A connect to high level, 24C connect to
low level. When the differential voltage up to 10V, it is
corresponding to the Max. position of the spool.
Caution: never connect to 22A and 24C to any port of the
