T4411 is a RS485Temperature transducer for Pt1000/3850ppm and is built in a durable watertight case. Temperature readings can be in Degrees Celsius and Fahrenheit and are user selectable. The Large dual line LCD is built in for live data view, although it can be switched off of necessary.

Computerized design ensures maximum long term stability and failure indication.

The T4411 uses external Pt1000 sesnors (a selection is available from our Sensors and Accessories tab) and is designed for use in Building management, HVAC and warehouses and can be connected to any product that accepts a RS485 input, including some of our own monitoring products.

Serial RS485 output

This transmitter works with ModBus RTU communication protocol or with Advantech ADAM compatible protocol. Protocol is user selectable in special configuration mode by means of the PC. Serial link enables to read actual readings and modify transmitter configuration. Instrument works always in slave mode, i.e. responds only to master device query. Transmitters have the address space available from 1 to 255. Communication speed is 110 to 115200Bd.

Tested with LabVIEW from National Instruments, TIRS.NET, ControlWeb, EasyView.
