I would like to know any company that could help me with wireless solution to be used to transmit analog signal to a PLC remotely.

 

Omnex Controls offers wireless transmission of analog and digital signals using radio XMTR/RCVRs.
I've used their product to send 4-20ma signals from flow transmitters to a SLC500 with good results.

 

If you want to allow for future expansion. Use an RTU such as the Action Controls King Fisher, "www.action-controls.com.au":www.action-controls.com.au

Or you can get an RTU plug on for a siemens S7 type PLC

 

Use the radio modem of Flotech on RS485 I have designed and implemented it in many of my projects using DCS system

quite well efficient

I'm not sure what afford means in your request, but NBT has the TSR900 which is a wireless RTU and the TSRLink which is complete end to end wireless analog. See "www.nbtwireless.com":http://www.nbtwireless.com
