Hi all

Dear i need to send 4-20 MA wireless to remote location distance is 8km.
What is best design for that.

I think to use S7-1200,AI SB and NANOBRIDGE in first location and use NANOBRIDGE, ET200S with AO in second location but i look for other design cheaper because its only one analogue signal.

Check out Data Linc Group CIX6435 i/o extenders. Use them at out sites up to 10 miles apart and work great.They send 4-20ma and digitals from a slave to a master via radio.Very accurate and dependable.

Also look at www.bannerengineering.com lots of wireless options at decent prices. Their strength is ease of use.

Don't use this stuff. I have had bad experience in the past. It's rubbish to be honest

Then it was not properly applied or installed. We have lots of it installed in many locations with no problems.

I have to agree and disagree. I agree because the first system I worked on was not layed out correctly. 80% system uptime at best. This syetm was only used for fault notification so no-one knew when it didn't work. We did a site survey and it was horrible. The original system was installed and worked perfectly. The customer built a new building between the two radios. I replaced the antennas and this system works perfectly.

I have installed 30+ systems. Every time I tried to cut corners and not do a site survey I have been sorry. I now do a site survey every time. These systems work flawlessly. The largest I have installed had 20 repeaters and 10 nodes going back to a Red Lion G306. A super clean system installation because I did the design upfront.

I'm sorry but I still have to disagree. We had to remove all of these installations from sites due to terrible communications. Surveys were conducted prior to design

I have had a number of successes with the Banner Engineering wireless. I've installed the older 900 MHz, 130mW radios and the 900MHz full 1 watt of power, both frequency hoppers.

I suspect the Swedish version is the 2.4Ghz version which I have no experience with.

Dan Banner is releasing several of the 2.4 in the US. I have done several proto type setups and configurations for them. Mainly for interfacing with Red Lion and AB Devices.

I am probably partial because they send me work.

As all are here, I am not in the business of "bad mouthing" products. Some have different experiences on different products. For me in this case it was a nightmare that did not need to be.

Setup: Good
Reliabilty: Poor
Tech Support: Extremely disappointing.

Changed to another system and works flawlessly. Of course one can say I had design issues due to to inthorough ( is this a word???) site surveys which I can accept. But I can assure you we have many successful installations in the Nordics with no issues.

Tech Support yet to call back with a solution to now redundant equipment and Pi&&sed off customer.

We don't like to bad mouth anyone or any company. I do like to discuss pros and cons of systems. The tech support issue is a shame. I may be because you are out of the US market. I know they sell stuff across the pond. It is disappointing to hear about bad supp.
