Remote I/O - HART


HART to Analog Converter and Loop Meter

Available Soon

The ICPDAS HRT-228-A4 HART Loop Converter enables the conversion of a digital multivariable HART signal into four independent 4 ~ 20 mA analog process variables. The HRT-228-A4 can apply in control or monitoring application to obtain up to four additional analog outputs without additional process penetrations.

The HRT-228-A4 allows up to four additional analog process variables from a multivariable transmitter or valve with no additional process penetrations. Besides, installed transparently across the 4~20 mA instrument loop, the HRT-228-A4 reads the HART digital process data that rides on the loop wires. The HRT-228-A4 converts the digital information for up to four isolated analog process signals that are readily accepted by in-place control system, such as DCS or PLC.

The HRT-228-A4 not only converts multivariable into analog process signal but also monitors the multivariable under/over limit intelligently. There are 4 built-in user programmable alarm output for monitoring. When a variable of transmitter under or over the user defined limit, the programmable alarm will activate automatically without DCS or PLC.
