US-DAS1 Single-channel proportional valve amplifier

● Without electrical position feedback

● Single solenoid

● DIN rail mounting

Abundant parameter configuration: multiple command input types, maximum/minimum current, ramp-up and ramp-down time, dither frequency, command dead zone and other parameters are configurable.

Wide voltage and current range: wide input voltage of 8~32 VDC, wide output current of 0~3 A, equipped with RS485 communication interface.

Supports Modbus RTU protocol to realize multi-unit communication and control.

Techbical Data

Wiring Example

Example 1
Give an analog command through PLC, CNC, acquisition card, etc.The analog command can be any signal of 0~5V, 0~10V, or 4~20mA.(Modify the parameter “PR1” to the corresponding command type

Example 2:
An analog command is given through a potentiometer, which isconnected to the 5V and 0V reference voltages of the amplifier. (ltis necessary to set the parameter “PA” to 5.) Note: lt isrecommended that the resistance value of the potentiometer be 5KΩor 10KΩ
