Product Specifications
This product is an industrial-standard analog output module supporting 8-channel synchronous output. It utilizes the Modbus RTU protocol and features built-in protection circuits such as power isolation, optocoupler isolation, self-resetting fuses, and TVS diodes.
Supports device address configuration (1–255) to allow cascading multiple devices via the RS485 bus
On-board voltage regulator chip supports a wide input voltage range of 7–36 V
On-board integrated power isolation provides a stable isolated voltage; no additional power supply is required for the isolated output
On-board integrated optocoupler isolation ensures signal isolation with high reliability and strong anti-interference capabilities
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, lightning, and static electricity
12-bit DA conversion using high-precision resistors ensures more accurate output data
Built-in watchdog ensures stable output and prevents system crashes
DIN-rail housing design supports stacking and combination, ensuring easy installation and safer operation
Three external LED indicators facilitate monitoring of MCU status and signal transmission/reception status
