CAR-4AD current acquisition module 
Module Features of CAR-4AD 
Input voltage type :0-5V, or 0-10V 
Input Current Type :0-20MAor 4-20MA 
Input and output channels: 4 channels input 
AD converted to 24Bit, AD conversion speed 100HZ/CH 
Resolution accuracy 0.1MV 
Using DC-DC isolated power mode, more stable signal acquisition 
Acquisition chip uses 24 AD, DA output 8-bit analog conversion 
Two switching outputs or two analog output (0-5V ,0-10V ,0-20MA ,4-20MA) 
1.1 modules: Introduction 
CAR series module using RS485 communication port, Based on the standard Modbus protocol, with extensive use of significance. 
Including the extension of the model input and output modules, analog input module, analog output module, 
temperature acquisition module. ​EX Series PLC, MD series of text display, and other related equipment to support 
Modbus protocol has been widely used in temperature, flow, level, pressure and other process control systems. 
1.2 Module size:
Shape and size of CAR series of modules, please refer to the following chart (unit: mm):

1.3 Full Power Isolation: 

CAR Series modules internal system are all isolated. And there are low and high pressure protection. Than the rated voltage, the system automatically power off. 1500V isolation test! Pay more attention to product quality!

Note: Isolated partial circuit diagram.
