High Safety

Safeguider built-in to ensure system safety

Universality

HMG patented self-adapted chip built-in. Conveniently connect to the network

Good Performance

: 1000V isolated voltage in inner, DC TO DC to isolate.

:350V photoelectrical isolated voltage between RS485 interface and module

:Up to 450V isolated voltage between channels by photoelectricity coupling utensil relay isolated

Convenient to Use  

RS485 communication output: only two signal wires needed can build a multi-dot distributed network; based on standard MODBUS-RTU protocol, can easily communicate with modern DCS, HMI, PLC etc intelligent equipment
