Analog input isolation grid receives 4-20mA signals or other current signals in the dangerous area of the site. After isolation and linearization, it is converted into linearized analog signals and output to the control system or other unit combination instrument in the safe area. At the same time, it supports digital signal transmission (HA RT).
