Programmable Temperature Transmitter w/ 4-20mA Output and MODBUS RTU Interface
Temperature / Transmitters / RT821

• MODBUS RTU Interface over 2-wire RS485
• NAMUR NE43 4-20mA current signal output
• Fully field re-programmable with module and PC based software
• Input for RTD Pt100 with 3-wire compensation

• Factory calibrated or customer calibrated
• DIN B In-head mounting

The RT821 temperature transmitter is designed for highest accuracy, stability and resolution. It is able to measure and linearize RTDs and convert measured values into engineering units in digital format. The data is transmitted via MODBUS RTU protocol over the RS-485 network. The digital signal is also converted into separate 4-20mA output. The device guarantees the highest performance stability for the most demanding temperature measurement applications. The advanced programming is done via personal computer and Pkit-RT821-1 developed by Intempco.

Information available from the RT821 in Modbus registers, includes: temperature, current output, configuration and information data (see user manual for the list of registers).
