4 20mA 24V LCD Digital Signal Generator DC Adjustable PLC Current Transmitter Tester Two Wire Output Dynamic Test DIY

Sale price $8.99 Regular price ~~$13.48~~

Tax included.

Description:

Power supply voltage:15V---30V

Output range:4-20mA/3-21mA

Display mode: Real Current / 0-100.0%/ 0-50.0Hz

Sampling resistance:Less than 500 ohms

Output accuracy:±0.5％;Display accuracy:0.01

Wiring Diagram:

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.

Simple test chart:

The instrument was stuffed in and stuck in both ears. Panel thickness must be greater than 1.4mm. Recommended opening size :77X40mm.

System operation:

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;

Parameter table 1:Entering F002-F007 (System Settings) requires a password “+ - - +”first

index	designation	comments			default
F001	Output mode	0: Coarse tuning mode,”F004” How many turns to rotate 1: Fine tuning mode,”F005” How many turns to rotate 2: Quick Output (Many products only need to validate a few values and test quickly in production.) 3: Automatic Curve Output (Be used for aging products) (Mode2.3 need to set parameters”F100” ”F200” >0 first)			0

F005	Add and sub value for fine tuning mode	1-50 Addition and subtraction for each pulse, No decimal point concept (1-50)			1
F006	Automatic save of Adjustment value	0: Not automatically saved (Need to press " Confirm " to save) 1: Automatic save			0
F007	calibration	-100-- +100 (be cautious in revising, about 20mA±4mA)
