Railduino 2.1 - RS485
6114.88 VAT excl.
Input / Output module based on Arduino platform
24x digital inputs, 12x relay outputs, 8x digital outputs, 2x analog inputs, 2x analog outputs, 1-wire, RS485 ...
Railduino module is a device working in connection with superior control system (e.g. Loxone) as so called distributed inputs / outputs. With this connection the control system is able to control external devices (e.g. lights, pumps etc.) using outputs or sense the values at the inputs of the module (e.g. buttons, contacts etc.).
Module is equipped with both digital and analog inputs. There are also relay, digital and analog outputs - see the table below. Module can handle 1-wire devices (Maxim/Dallas) as favourite temperature sensors DS18B20 or DS2438 (Unica 1wire sens. module).
Inputs/outputs can be read/controlled by communication bus RS485 or by LAN within computer network. Both types of connections communicate using UDP protocol (User defined protocol). There can be connected up to 15 Railduino modules within the same network/bus.
Version 2.1 - better protection of internal power supply, removed bug for L4 output, improved EMC compatibility

2. "How long it will take from pushing the wall switch to actually switching on the lights?"
3. "Is it possible to connect more then one Railduino to the same bus?"
I use two railduino's to extend the functionality of my loxone miniserver. I use the loxone rs485 extension to connect them because I wanted a dedicated connection for the railduino without having to rely on the LAN network. I simply added them to my loxone configuration and everything works as expected.
