Product Overview:

Technical service hotline:

The DTD122FHC mixed signal wireless transmitter of the Datai 1 series consists of a wireless signal transmitting terminal and a wireless signal receiving terminal. The so-called "mixed signal" refers to a terminal that has both analog and switch signals.

The transmitting terminal simultaneously collects standard 4-20mA current signals and switch signals, and transmits them through fully digital wireless communication. The remote receiving terminal immediately processes and outputs multiple relay switches and 4-20mA current signals upon receiving the signal from the transmitting terminal,

It can be connected to display instruments, PLC or DCS equipment and drive actuators such as solenoid valves and frequency converters. The functional diagram of the DTD122HFC wireless transmitter is as follows:
