Radio Modem

[asterof]

I have 4 digital IO signals on a remote shuttle
I need to radio modem back to 4 Digital Input Points
on a 1771-IA16

I am looking for a Radio Modem With Digital IO points
Do not need an communication protocols
Anyone ever used these

So the two transceivers would need 4 in and 4 outputs

Thanks

Check these
http://www.bb-elec.com/Products/Wireless-Cellular/Zlinx-Wireless-Modems-and-I-O.aspx

I have used them before easy to setup they just work
I actually use them to get remote access to crane drives without having to clime up

The 120VAC levels are going to present a problem depending on which device you choose.

Space can be a problem depending on which device you choose.

I have used these:

The pros are reasonable cost and compact size.
The cons are that you have to buy a programming module to set them up and they are not the most well built devices. For one of mine, I had to attach the programmer module and twist it and hold it my hand "in a bind" to keep connectivity long enough to get it configured. Once I got it installed it seems to work just fine. My situation was for analog I/O which required some non-standard configuration. You might be able to buy the pair of devices pre-programmed so you don't need to purchase that separate device.

DataLinc group makes a pretty good product. It has some pros and cons as they all do. I have used their PlantLinc hardware in some cases where the poor electrical conditions combined with the fact that all the I/O on the remote devices have commons internally tied to each other and ground rendering them unreliable. Their setup software does not play well with OS newer than WindowsXP in my experience as well. The are built in a nice rugged but bulky housing with lots of handy indicator LEDs. You'd need interposing relays to be able to use them with 120vac signals.

The best radio I/O devices I have used are Phoenix Contact TWE (trusted wireless ethernet):

They are not cheap but they hold up well in hostile temperatures and horrible electrical sites. They do have RS-232 and RS-485 ports so you don't have to use the Ethernet. The I/O can be added on in a modular fashion. Many of my sites are at the end of electrical transmission lines and controlling big water well pumps which generate bad surges and sometime ground current noise. The TWE has not suffered in these conditions so far. Setting them up for my applications took a little bit of head scratching since I was talking Modbus to them and not just doing simple point to point I/O replication. Once I figured out what their terms meant in my world, it was easy. All of the setup is done with a browser.

Phoenix also makes a Radioline which I have not used yet, but might be right up your alley. It looks a lot like the B&B stuff, but probably costs more and might be worth the money if it is better built. Love their products...website not so much:

Like OkiePC, I've used Phoenix Contact and can vouch for it. The Radio link is Trusted Wireless Version 2, a little bit less expensive than the original Trusted Wireless (V1) and the current generation.

1. Phoenix Contact RadioLink (Trusted Wireless version 2) needs no software to setup for point to point. https://www.phoenixcontact.com/online/portal/us?1dmy&urile=wcm%3apath%3a/usen/web/main/products/list_pages/Trusted_Wireless_2_0_P-26-03-05-01/9a570c67-dbf1-4681-bc1a-d5da56e1f32f
The Discrete I/O module, I/O extension module - RAD-DI4-IFS - 2901535, is 0-250Vac, not just 10-30Vdc.

RadioLink needs a Confstick - a $50 memory module of sorts to 'remember' the network ID.

2) Banner Engineering Premapped Radio requires no setup for discrete I/O.

One pair of PM2 radios push button configured for the 1N network does 4 DI on one end, 4 DO on the other end.

Discrete I/O is 10-30Vdc, not 115Vac, so you'd need interposing relays

I've used Banner, too. Either is a quality radio, 900MHz freq hopping with punch through capability.

as was said before, the b&b work great.

I ran across these, which are a fraction of the price, operate at a low frequency and a much greater power output. If you have obstacles this guy will go thru them at this freq and power. Ive havent used them but seen them used alot in oil and gas. I probably would shoot for the phoenix or b&b, but if money is an issue this guy may be the ticket.

They're a bit pricy but I've found them to be very reliable - cheek out Elpro wireless IO - http://www.cooperindustries.com/content/public/en/bussmann/wireless/brands/elpro.html

These units are simplex only meaning that they only transmit I/O data in one direction. They are also Citizens band frequency devices (which is why they are simplex. You can’t do bi-directional data on CB frequencies) so you have to be careful that you’re not installing them in an area that has a lot of CB traffic. It’s getting pretty easy to do that these days but there are still a lot of interstate truckers that use CB’s and you can find areas with a lot of traffic.
