Hydraulic Pneumatic Electronic Systems. Single and Dual Output Programmable Proportional Solenoid Driver

Transcription

1 Single and Output Programmable Solenoid Driver By now, you may have used heard about electro-hydraulic proptional solenoid driver. When dering this driver, the engineers need to determine in advance what type of input signal, output signal, and processing features they might want to have in their design. With the technology available today, we offer a programmable integrated electro-hydraulic single dual solenoid driver which gives the engineers the flexibility to set and reset what is required in their application. On top of that, we include the output display feature to eliminate any guess wk on what the actual output power level is. This feature alone will save your technician and maintenance personnel troubleshooting time. The -O is a DIN rail mounted Single Output Programmable Driver f open loop control systems. The ramp time could be disabled f maximum response time f closed loop applications. The 2-O is a DIN rail mounted Output Programmable Driver f open loop control systems, designed to drive any brand of hydraulic and pneumatic proptional valve up to 2.5A. A single input command will drive the output A and output B automatically and the ramp time could be disabled f maximum response time f closed loop applications. The -C & 2-C is a DIN rail mounted Single and Output Programmable Driver f closed loop control systems. It utilize a PID control algithm with programmable digital gain settings. (Currently in development - to be released in January 2005) Power conversion, software and cable f Palm PDA and Windows operating systems.

2 Pressure Control Many different proptional pressure relief valve is designed to wks in different way. To achieve the same objective, this Single Driver is designed to give the engineer the flexibility to control the pressure setting at low cost. Engineer can set reset the control features within the without actually changing the electronic amplifier. Pressure control can be set by an Command signal by Softshift Digital Input A1 A2. Flow Control This Single Driver can provide a proptional flow control to control the acceleration, speed, and the deceleration of wide range of applications. Use Program to do the followings: Select Digital Control. Set IN-A1 Output Current. Set IN-A2 Output Current. IN-A1 and IN-A2 will share the same parameter setup: Deadband; Ramp Time; Dither Freq. and Amplitude Open Loop Control System, Output is ramped by Digital Softshift Command Typical Connection OUTPUTS GND 8 Out + 10 Out - 11 Vdc Command 0-5 Vdc 1-5 Vdc 0-10 vdc Prop.

3 By now, you may have used heard about electro-hydraulic proptional solenoid driver. When dering this driver, the engineers need to determine in advance what type of input signal, output signal, and processing features they might want to have in their design. With the technology available today, we offer a programmable integrated electro-hydraulic single dual solenoid driver which gives the engineers the flexibility to set and reset what is required in their application. On top of that, we include the output display feature to eliminate any guess wk on what the actual output power level is. This feature alone will save your technician and maintenance personnel troubleshooting time. Directional Control direction control valves control both the direction and the amount of flow in response to an electrical signal. This Driver is designed to respond to the electronic input command signal, controlling the electrical output to drive the proptional valve. Engineer and technician have a wide range of flexibility to set and reset the control features within the without actually changing the electronic amplifier. Application Using the programming tool, the engineer technician has the option to program the following parameters: Input (Select One) +/- 5 vdc +/- 10 vdc +/- 20 ma (5k Ohms) Output (Enter Value) Maximum Output Level 0.5A to 2.5A Features Accel.Ramp Time 10 msec to 10 sec.* Decel.Ramp Time 10 msec to 10 sec.* Deadband Comp: 0-10% ** Dither Amp: 0-10% ** Dither Freq: hz Control ON/Bypass * To disable Ramp Time, set Ramp Time to 0.

This signal must remain high energized to turn Output on and can not be bypassed by the program. This connection could be used f soft emergency stop signal. Term-15: Digital Input IN-A Digital Input IN-A could be programmed as Softshift f Output A ( Single Output -O). When this input is energized, the Output A will be ramped to a preset current accding to the programmed Ramp Time (10 msec to 10 sec). Contact: Term-16: Digital Input IN-B Digital Input IN-B could be programmed as Softshift f Output B ( Output 2-O). When this input is energized, the Output B will be ramped to a preset current accding to the programmed Ramp Time (10 msec to 10 sec). Digital Inputs IN-A and IN-B Softshift Control If both digital inputs are triggered (ON), only one output, based on first trigger first serve, will be executed. Both digital inputs must be disabled to utilize the analog command. All other programmed features, such as Dither Frequency, Dither Amplitude, Deadband Compensation will be executed accdingly.

5 Applications Accurate control of hydraulic and pneumatic proptional solenoid valves used in industrial and mobile equipment control system. The combination of proptional valve and this Programmable Driver offers low cost solutions to many hydraulic and pneumatic applications with Power Level Output display f ease of troubleshooting and maintenance. Closed Loop Applications The -O and 2-O can be used f closed loop applications.
