Remote Monitoring of Analog Inputs
Remotely monitoring Analog Inputs (4-20mA) on web browser or mobile.

Hello,

I need to monitor remotely 5 Analog Inputs (4-20mA) on web browser or mobile. Which module should i use.

Supply 24vdc
4-20mA range 0-360MW

Thanks

Acromag's 963EN-4012 module converts multiple 4-20's to Modbus/TCP

Opto22's Groov can get the Modbus/TCP data and shovel it into the Ether.

Thx very much. I will study in detail. But i need more simple solution from this. e.g

This is a low cost PLC with a web server: http://www.triplc.com/fmd8810.htm

If you want to add trending, alarming and automatic report emails and a super nice mobile display check out Mango at https://infiniteautomation.com/mango-overview/
to work with any analog IO device or PLC

What type of internet connection do you have or need?

Thx for you reply. But i need more simple solution from this. e.g

This module provides single 4-20mA to be available on internet through their cloud service but several module can be combined. Further my 4-20mA channel is sourcing, i.e The output channel (4-20mA) of PLC displays on local 4-20mA display. Can i use that loop for above device.

Thx

Assuming that you will be connected via Cell Modem and need to keep data bandwidth low, I would use the Acromag as previously suggested (I have used them over Ethernet), and then build a small app in excel to go and get the data using Modbus/TCP.

Easy Peasy but not cheap!

You can use the DAT8017-I it has 8 channels. It has free software and user guides to get it on to the web browser.
