Can anyone recommend a good analog input module that meets the following criteria

8 channel remote analog Input module (or combination of smaller blocks)
Modbus protocol to commincate with Paragon TNT plus suitable PC card
Inbuilt or local power supply (not 4 wire system)
0-20mA and 0-5V inputs

 

Hello,

I would look at Modicon's Momentum product http://www.modicon.com. Use the
smallest Momentum processor 171CCS70000 and the 170AAI03000 8 channel Analog
input I/O base. This will provide you with the your 8 channels of analog in
and your Modbus communication requirement. You also have the ability to have
local intelligence if needed.
