Advantage of RS-485 Interface

Providing the feature of RS 485 digital serial interface is advantageous, since the number of wires coming from the various sensors / transmitters can be avoided and instead, only two wires can be used to interface multiple such FTX-3000 on serial port. The digital communication has the greatest advantage of exactly replicating the process value, that is what is measured at the plant and what is displayed in the control room always matches one to one as compared to transmitting the analogue values. In today’s technology, most of the PLCs and DCS accepts RS485 digital interface.

Parameters	Description
Process Input	Thermocouple or RTD (Pt-100) or (4-20)mA signal. (Input type not listed in the table below can also be provided on request)
Range	Full range of the selected input – desired measuring range can be chosen from range selection table.
Accuracy	Software linearized for +/-1 °C indicating accuracy for thermocouple input and +/-0.1 °C for Pt-100 input. For Voltage and Current – the accuracy is absolute to the process input.
