HDC current and voltage signal source panel-mounted signal source manual regulator

Current and voltage signal source
(Panel-mounted signal source/manual regulator)
Overview The current and voltage signal source is a panel-mounted precision instrument that integrates DC voltage and current output, also known as DC signal source. , panel-mounted signal source. It can output two signals, DC voltage and current, and can be used for test and verification of valves and secondary instruments. Double row display (respectively for voltage and current output values such as,,,,, etc.
Current and voltage signal source can be installed on the control box and control cabinet for manual adjustment equipment, and can be used as a manual regulator and handheld operator adjustment panel .You can also choose a signal source output and an on-site signal feedback input at the same time. When controlling the valve, the operable signal can be connected to the valve to control the valve opening.
One function: current and voltage signal source
◇ Through the panel The output value can be changed by pressing the button, which is continuously adjustable. (With fast and slow adjustment keys)
◇ Small size, simple and convenient to use, panel-mounted, easy to use when calibrating and adjusting the instrument.
◇ Adopted With advanced microcomputer chip and digital filtering technologies, the whole machine has strong anti-interference ability and stability.
◇ Continuously adjustable Continuously adjustable Continuously adjustable optional dual output.
◇ With shortcut Output key can quickly adjust the valve switch.
◇ The control valve can operate the signal to connect to the valve and control the valve opening

Four operating instructions Current and voltage signal source
Ⅰ Electrical automatic Check
Connect the power input, output, alarm and other wiring of the instrument according to the terminal wiring diagram of the instrument.
Carefully check the wiring of the instrument and turn on the power only after it is correct.
After turning on the power, the upper row of the instrument The words displayed in the lower row indicate that the instrument has passed the self-test.
Ⅱ Explanation
The upper row displays the voltage value, and the lower row displays the current value. The displayed value corresponds to the size of the instrument's output current or voltage signal.
For slow adjustment, each time you press the ▲ key, the output will increase. Press the ▼ key once, and the output will decrease
For fast adjustment, if you press the ▲ or ▼ key without moving, the meter display value will increase or decrease rapidly, and it will stop when you let go.
/ key directly switches the output and
current and voltage signal sources. It is simple and convenient to use. It is an essential instrument for factory production and laboratory testing and calibration. Multiple units can be assembled in one control cabinet to achieve multi-channel Current and voltage signal output.
