1. Modbus RTU Analog Output 8CH is an industrial standard analog output module, supports 8-ch simultaneous output. Adopts Modbus RTU protocol with built-in protection circuits such as power isolation, magnetical isolation, resettable fuse, and TVS.
2. Supports setting device address (1 to 255) to cascade multiple devices via RS485 bus.
3. On-board voltage regulator chip supports wide voltage supply from 7 to 36V.
4. On-board integrated power isolation provides stable isolation voltage; the isolated end requires no additional power supply.
5. On-board integrated magnetic coupling isolation enables signal isolation, with high reliability and strong anti-interference capability.
6. On-board self-recovery fuse and TVS (Transient Voltage Suppressor) effectively suppress surge voltage and transient spike voltage in the circuit, protecting against overcurrent, overvoltage, lightning, and static electricity.
7. 12-bit DA conversion with high-precision resistors ensures more accurate output data.
8. Built-in watchdog ensures stable output without crashing.
9. Rail-mounted enclosure design supports stackable combination, enabling easy installation and safer use.
10. External 3 LED indicators for convenient viewing of MCU status and signal transmission/reception status.
