4-20mA Current 4-channel Current Signal Generator Module Board Digital Source Transmitter with LCD Display

Description

Features:
Supports 12864 LCD display for clear and easy reading the data.
Multi-channel current signal generator, which can generates 4 channels current signal simultaneously.
Easy to operate, you can input data by keystroke operation, and then the output signal will be adapted immediately, very easy and simple to use.
Supports polarity protection of input voltage, safe and reliable to use.
With excellent performance, which features 4~20mA active output current, 0.01mA display resolution and 0.1mA control accuracy, providing accurate and precise data for you.
Can analog transmitter output.
Compatible for signal generator, valve regulator and instrument calibration to meet different uses.

Using Methods Steps:
* Output current OUT1 setting: Press K1 or K5 Key to switch to OUT1 Setup interface. Press K2 or K3, output current value increases 0.01 MA step by step. Hold down K2 or K3, output current value increases 0.01MA step by step.
* Output current OUT2 setting: Press K1 or K5 Key to switch to OUT2 Setup interface. Press K2 or K3, output current value increases 0.01 MA step by step. Hold down K2 or K3, output current value increases 0.01MA step by step.
* Output current OUT3 setting: Press K1 or K5 Key to switch to OUT3 Setup interface. Press K2 or K3, output current value increases 0.01 MA step by step. Hold down K2 or K3, output current value increases 0.01MA step by step.
* Output current OUT4 setting: Press K1 or K5 Key to switch to OUT4 Setup interface. Press K2 or K3, output current value increases 0.01 MA step by step. Hold down K2 or K3 output, current value increases 0.01MA step by step.
