HART475 Communicator/Handheld Field Communicator
The HART475 Communicator is an upgraded version of the HART375 Communicator that is used with instruments that use the HART communication protocol to set, change, and display it to monitor input/output values and self-diagnosis results. Set the output and zero of constant current. When the system is started or maintained, the HART communicator can be used by connecting it to the 4~20mA communication signal line.
This communicator is suitable for the communication operation of HART protocol intelligent transmitter. It is compatible with HART275, HART375 and HART475. It has excellent compatibility. It can communicate with imported instruments of 1151, 3051, EJA, ABB and other HART protocols. It is fully compatible with domestically produced ones. A variety of intelligent pressure (temperature) transmitters, at the same time, can also communicate with electromagnetic flowmeters, V-cone flowmeters, target flowmeters, vortex flowmeters and other flowmeters that support the HART protocol.
Features:
Modulation signal does not interrupt 4~20mA DC signal during online monitoring and communication communication
HART Communicator can be used with instruments that use the HART communication protocol to work with all instruments that use the HART communication protocol.
Easy operation and large display screen (4 lines, 18 characters per line), displayed in Chinese, the user can see at a glance, easy to set and change
Information self-diagnosis/protection function
