Hi
Has anyone come across or used some simple remote control hardware. I only need 4 digital push buttons to be sent to the PLCs digital inputs from a couple of battery powered handheld remote units. What I'm after is really like a 'rugged' remote garage door opener with push buttons. It would be useful if it had a couple of spare IO as well although that would be optional..
Thanks
