RTA offers a variety of

ALLEN-BRADLEY LEGACY

communication solutions

Legacy – sounds old, that’s because it is! That doesn’t mean that you still don’t need connectivity solutions to keep your legacy DF1 or DH+ protocols running on your factory floor.

For example, your DF1 protocol, used by Allen-Bradley for so many years, is no longer supported by A-B. So, how are you going to connect an RS-232 cable from your computer to a decades-old PLC?

Or the DH+ (Data Highway) protocol developed by Allen-Bradley in the 1970s was widely adopted, and your previous suppliers are no longer supporting connectivity solutions you were using, what is the solution?

The answer to both is simple, with Real Time Automation’s legacy gateways, that’s how!

Products That Keep Your Factory Floors Connected

RTA, an authority on industrial communications, has a wide range of gateways that support these legacy communications, so users get a simple, easy-to-use connectivity solution to integrate their DF1 or DH+ devices into other industrial protocol networks. Our legacy gateways are made in the USA, come with Enginerd® support and are in stock, ready to ship the same day when you order before 2:00 pm CST.

And if you need to replace your Allen-Bradley 1761-NET-AIC or 1761-NET-ENI, we have solutions for that, too.

What Our Customers Are Saying

I tried for several months to find someone who knew the older Allen-Bradley RB modules…. After almost a year of searching for help, RTA fixed our problem in a few short weeks.

John M.

The 435NBA is an excellent serial to EtherNet interface to an Allen-Bradley ControlLogix PLC. Great web interface makes it easy. We will be using more of these in the future.
