Key Features

8-channel high precision isolated analog output for process control.

Each channel provides independent galvanic isolation to avoid ground loop noise interference.

Stable drive capability for field devices such as valve positioners and I/P converters.

Supports redundant fieldbus communication to ensure reliable control output.

Equipped with self-diagnostic circuit and LED status indication.

Allows hot-swap replacement without system downtime.

Application Introduction

Converts digital control commands from DCS into standard 4–20 mA analog signals to regulate control valves, actuators and I/P converters.

Widely applied in chemical, petrochemical, power generation, oil gas and water treatment industries.

Used for closed-loop regulation of temperature, pressure, flow and liquid level parameters.
