The Waveshare 8-Channel Industrial Analog Output Module w/ 12-Bit DA Conversion (Modbus RTU) is designed to meet the rigorous demands of industrial environments. This module facilitates eight-channel simultaneous analog output, capable of both voltage and current modes. It features a 12-bit digital-to-analog conversion for high-precision output data and adopts the Modbus RTU protocol for communication. The device is equipped with built-in protection circuits, including power and magnetic isolation, which enhance its reliability and anti-interference capabilities.
The module allows for configurable device addresses, enabling the cascading of multiple devices on an RS485 bus. It includes an onboard voltage regulator compatible with a wide range of power supplies and integrates unibody power supply isolation to deliver stable isolated voltage without the need for an additional power source. Additionally, the module's magnetic isolation ensures signal integrity and robustness against interference.
For enhanced circuit protection, the module is outfitted with a resettable fuse and a Transient Voltage Suppressor (TVS), which work together to mitigate surge voltage and transient spikes, while also providing over-current and over-voltage protection. The onboard watchdog contributes to stable output performance. The module's rail-mount case design facilitates easy installation and secure stacking for multiple modules.
The module supports two output modes: a current output with a range of 0~20mA and a voltage output with a range of 0~10V. It is capable of sending Modbus RTU protocol commands via an RS485 interface and outputting data to sensors within the specified ranges. The industrial-grade isolated protection ensures stable operation, with dual isolation for both power and signal on the RS485 communication interface. The module's construction includes a built-in fuse and anti-reverse protection, further enhancing its suitability for challenging industrial settings.
Please note that the module should be handled with care, considering the built-in protection against lightning and electrostatic discharge. Proper installation and maintenance are essential to ensure the module's performance and longevity.
