I. product overview

HART475 intelligent hand controller is suitable for the communication operation of HART protocol intelligent transmitter, with excellent compatibility, it can communicate with 1151,3051, EJA,ABB and HART protocol import instrument of flow, fully compatible with various domestic intelligent transmitter. An updated version of the 375 operator, it works with instruments using the HART communication protocol to set, change, and display input/output values and self-diagnostic results. Set constant current output and zero setting. When the system starts or maintains the operation, as long as the HART it and USES together with the instrument which adopts the HART communication protocol, carries on the setting, the change and the display, it may monitor the input/output value and the self-diagnosis result. Set constant current output and zero setting.

Ii. Working principle

HART475 smart hand controller is a portable terminal, which can be used together with instruments using HART communication protocol to set, change and display. It can monitor input/output value and self-diagnosis result. Set constant current output and zero setting. When the system is in operation or maintenance operation, as long as HART475 HART communicator is connected to the 4~20mA communication signal line, it can be used.

Iii. Application:

1. Fully support all qualified HART communications;
