This portable custom built unit compliments the service technicians ability to test hydraulic proportional valves. It contains an interchangeable corresponding electronic amplifier card for the various valves and an internal variable power supply. It is powered by a regular 120 volt AC outlet and uses standard DIN 43650 connectors for the valve (cables on the back). This unit also has precision voltage and current digital meters and can isolate exiting machine valve controls to assist in quik troubleshooting results or for just plain proportional valve and control testing.

This particular custom built portable unit supplies multiple precision variable signals in either voltage or current using the industry standards of 0-10 volts DC (5 channels) and 4 – 20 mA (6 channels). It is powered by a regular 120 volt AC outlet and utilizes standard DIN 4650 connectors.

This custom built unit provides a reduced high speed isolated 1.5 volt DC signal to a computer whenever a valve is energized. It is capable of interfacing larger voltages of up to two directional valves to a low signal for hi speed monitoring.

Shown here is a hand held, battery operated signal driver for testing purposes. It supplies an accurate variable 0 – 10 volt DC or 4 -20 mA input with a digital LCD readout. It utilizes standard banana plugs and is made of a durable PVC shell.

This unit offers ease and simplicity to testing equipment that relies on a variable signal. It can provide a variable signal and show the actual value of the equipment being tested. It also has the capability to reverse the polarity of the signal. This particular unit compares a proportional hydraulic valve 0 – 10 VDC input signal with the valves corresponding LVDT and can be used to provide calibration or determine functionality. It utilizes standard hydraulic connection cable (on back) and uses a regular 120 volt AC outlet.

This custom built portable unit provides testing of hydraulic pumps and motors and their incorporated serve value with control and measurement. It also has the ability to easily switch it’s on board hydraulic amplifier card to different models to test many models of hydraulic pumps and motors. This particular unit allows for your standard multi-mater plug into many of it’s test points and also allows for different signal voltage or current inputs.

This custom made unit provides the technician the ability to remove the electronic controls from a hydraulic pump and perform tests by eliminating the existing controls and replacing the control system with this unit. It is designed with simplicity for the basic hydraulic technician and with a high degree of durability for travel use.
