Feature:
Current and voltage signal generator TGC1700 series, can produce dual 0-20mA current signal and 0-10V voltage signal.

The module is easy to use, input data through key operation, and immediately update the output signal.

-1602 display with backlight, standard LCD 1602 interface.

-Active current 0-20mA output, display resolution 0.001mA, control accuracy 0.1mA

Voltage 0-10V output, display resolution 0.001V, load current less than 10mA

Input voltage polarity protection

Simulate the output of the transmitter

 Applications:

 Signal generator

Value regulator

Instrument calibration

 Power Interface:

 CN1 "+" indicates positive input power

CN1 "-" indicates the negative input power (GND)

 Output signal:

 CN2 "OI" indicates active current output

CN2 "G" indicates active current output common (GND)

CN3 "OV" indicates voltage output

CN3 "G" indicates the voltage output common (GND)

 Use method and procedure:

 FN: Function switching

Press FN (K4)"-" the cursor moves up and down in the first and second lines. Switch current and voltage output gears.

SET: Shift operation

Press SET (K3): The "-" cursor moves to the left and adjusts the increment and decrease steps. "-" indicates the current output bit to be set.

UP: (K1) Incremental increase

DN: (K2) Incremental reduction

Power supply and connection annunciator, push the code switch S1 to turn on the power, the display screen lights up, display as shown:

Current output setting: Press function to switch FN key. when the cursor is displayed on the first line "1.0I->04.000MA", press SET to move the cursor to the output bit to be set, press UP or DN to increase or decrease the value. The operating data will be updated on the OI output port.

Voltage output setting: When FN key is switched by function, the cursor moves to the second line "2.0V->01.000V" display. Press SET to move the cursor to the output bit to be set, press UP or DN to increase or decrease the value. The operating data will be updated on the OV output port.

 The figure "MA" shows: Current MA signal output

 Precautions:

 Before applying power, make sure that the positive and negative poles of the power supply are correctly connected.

Do not splash water on the annunciator and it will make the system work abnormally.

Please place the annunciator on a flat insulating object.

Maximum current output 20mA, maximum load 500ohm.

Maximum voltage output 10V, load resistance >3Kohm.

The maximum allowable voltage: 30V (each terminal and each terminal to be ground)
