Features:
1. Supports a wide supply voltage range of 7V–36V and allows for device address configuration (1–255) to enable daisy-chaining of multiple devices via the RS-485 bus
2. Supports power isolation and magnetic coupling isolation, enabling dual isolation of both power and signals in the communication section, resulting in high reliability and strong interference resistance
3. On-board self-resetting fuses and TVS (transient voltage suppressors) effectively suppress surge voltages and transient spikes in the circuit, providing protection against overcurrent, overvoltage, thunderstorms strikes, and static electricity
4. Digital inputs feature bidirectional optocoupler isolation, support both passive and active digital inputs, and include a built-in debouncing algorithm; relays support either linked mode or toggle mode control
5. 12-bit high-precision data acquisition, multiple input range modes, supports single-ended/differential inputs, and simultaneous voltage and current acquisition
6. Utilizes high-precision resistors and zero-drift precision operational amplifiers for more accurate output and data acquisition
7. Equipped with high-quality relays; supports loads of up to 10A at 250V AC or 10A at 30V DC
8. DIN-rail-mountable, flame-retardant PC protective housing ensures easy installation and safer, more reliable operation
9. Three external LED indicators facilitate monitoring of the MCU status and signal transmission/reception status
