RT-PA893 Proportional amplifier for Proportional Valve
- control proportional valves with one or two solenoids .
- The input signal is either voltage or current, and the output current is closed-loop.
- Adjustable maximum, minimum, ramp, pulse width modulation frequency by potentiometer 5>Current range (per DIL switch) up to 2.6 A
The RT-PA237-893 series digital proportional valve amplifiers are used to control proportional valves with one or two solenoids and can be optimally adapted to various proportional valves by adjusting the parameters. The input signal is either voltage or current, and the output current is closed-loop, so it is not affected by changes in supply voltage or solenoid coil impedance.
Features:
- Power amplification of proportional valve
- Built-in advanced MCU
- Introduction of compact structure
- Adjustable maximum, minimum, ramp, pulse width modulation frequency by potentiometer 5>Current range (per DIL switch) up to 2.6 A
RT-PA-237-893/V1 Maximum output current of 0.6 A and 1.2 A for RT RT3DREE series proportional directional valves or other pressure valves
RT-PA-237-893/V2 for RT RT4WRA series proportional directional valves
