The new Tempus Decoder system represents an unique solution on the market: it is the only decoder system that works in Wi-Fi connection. This system allows to manage up to 48 stations with a single controller and expanding the system is simple: it is always possible to add new decoders at a later time. The Tempus Decoder System has two main components: the Interface and the Decoders. The TEMPUS-2W interface turns your Tempus controller into a 2-wire system: this will make life easier for you and your customers. Why use multiple cables when only two are enough? Save time, labor and wiring costs! The decoder T2W-101 is the device that receives the message from the interface and drives the solenoid.
