main feature:
1, passive two-wire 4-20MA current loop, the wiring is fully compatible with 2, 3, 4 wire system
2, 0.05 precision, liquid crystal display, encoder knob, termial block is not positive or negative
3, can set the coarse and fine adjustment mode, the number of turns can be set
4, can set the output range: 4-20MA (control equipment) / 3-21MA (debug signal)
5, can be set display mode: actual current / 100.0% / 50.0HZ
6, linear output, can be calibrated
7, can be set to automatically store the output value
8, programmable automatic curve output cycle 1-9 segment
9, can set 2-9 points to quickly adjust the output, the knob directly calls these currents
Two connection terminals are non polarity;
Anyway wiring, the principle is to generate a current loop circuit.
This signal generator can use 4-20mA to generate voltage and control the current in the circuit.
System operation:
Parameter Settings:(Rotate one grid clockwise is "+" Rotate one grid counter-clockwise is "-", Press the knob. is"Confirm")
1. Press and hold the knob for 2 seconds to enter the parameter setting, Display parameter number "F001", Then press "Confirm ", to Set the value of parameter "F001", =0 is coarse tuning; =1 Fine tuning; Then press "Confirm" to save its value.
2. When the parameter number "FXXX" is displayed, "+" "-" Rotation modification parameter number; Enter the password first "+ - - +", To enter the F002 parameter; Enter the password first "+ - + -", To enter the F100 parameter; Enter the password first "- + - +", To enter the F200 parameter.
