Specifications:
This product is an industrial-standard analog acquisition module supporting 8-channel synchronous acquisition across multiple ranges. It utilizes the Modbus RTU protocol and incorporates protection circuits such as power isolation, optocoupler isolation, self-resetting fuses, and TVS diodes.
Supports device address configuration (1–255) to allow cascading of 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; the isolated output requires no additional power supply
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 high-precision data acquisition with multiple input range modes; supports single-ended/differential inputs and simultaneous voltage and current measurement
Utilizes high-precision resistors and zero-drift precision operational amplifiers for more accurate data acquisition
Built-in oversampling digital filtering algorithm and watchdog timer ensure stable output without system crashes
DIN-rail housing design supports stacking and combination, offering convenient installation and enhanced safety
Three external LED indicators facilitate monitoring of MCU status and signal transmission/reception status
