Wireless button

[idell]

Hi folk! We have a system based on Simatic S7-300, need to control some discrete inputs through wireless buttons, max distance will be 100 meters. What solutions do you know?

Something like this perhaps? http://www.controlchief.com/sk1400.html
You would have to check there sales and support outside the U.S. however

On much greater distances too.

I have used http://www.rfsolutions.co.uk/ and was impressed by the range and the fact that walls and machinery did not seem to affect performance.

How about something like this?

I've used a lighter duty unit like this in place of a line jog pendant. Seemed a lot easier than string 100 foot of wire cable and multiconductor wire. the buttons on the wireless pendant control relays in the reciever unit. The range of the unit in the link is 500 ft.

Be aware, that batteryless ones transmit only their transitions, but do not transmit pressed status continuously.
