The HD1000 series isolators use optical, electrical and magnetic isolation technologies to isolate the power supply, input signal and output signal from one another in pairs, achieving isolated signal transmission between field devices and the control system. They are isolation interface units between field devices and control room equipment.
Isolation technology fully isolates input and output signals electrically, significantly improving the immunity to interference and reliability of electronic systems. The full series covers RTD temperature signal transmitters, thermocouple temperature signal transmitters, millivolt signal transmitters, distributors, signal splitters and intermediate drive relays.

DCS analogue isolation
Install isolators on the 4~20mA loop on the control room side to eliminate earth circulating currents and common-mode interference.
Temperature signal transmission
Field RTDs/thermocouples are converted by isolators to (4~20)mA and fed to PLC analogue cards.
