Programmable Signal Isolator with Optical Isolation

The HHD programmable signal isolator is designed for signal isolation, distribution, conversion, and transmitter power supply in industrial automation systems. Its optical isolation technology provides an isolation withstand voltage of up to 2500 V, helping eliminate ground loops, reduce electrical interference, and protect PLCs, controllers, and data acquisition equipment.

With accuracy up to ±0.1%, the device supports configurable 4–20 mA, 0–10 V, 0–5 V, and RS485 Modbus RTU input and output signals, depending on the selected model. It can convert different signal types, distribute one input signal to multiple isolated outputs, and provide power to field transmitters.

Available channel configurations include 1 input/1 output, 1 input/2 outputs, 1 input/3 outputs, 1 input/4 outputs, and 2 inputs/2 outputs. The compact structure is suitable for installation inside control cabinets and easy integration with PLC, HMI, SCADA, industrial IoT, and remote monitoring systems.
