Waveshare Industrial Modbus RTU 8-Ch (B) Analog Output Module 12-bit DA Conversion
The Waveshare Industrial Modbus RTU 8-Ch (B) Analog Output Module is a high-performance, industrial-grade solution designed for precise and reliable voltage signal generation in demanding automation environments. At its core, this module features a high-precision 12-bit DA conversion architecture, delivering a stable 0~10V analog voltage output across 8 simultaneous channels with an impressive 1mV resolution and ±0.01V output accuracy.
Built to withstand electrically noisy industrial settings, it incorporates comprehensive protection circuits, including unibody power and magnetic signal isolation, TVS (Transient Voltage Suppressor) for lightning and electrostatic discharge protection, and resettable fuses for over-current and over-voltage safety.
Communicating seamlessly via the standard Modbus RTU protocol over an RS485 interface, it supports flexible baud rates ranging from 4800 to 256,000 and allows up to 255 configurable device addresses for effortless multi-device cascading.
Powered by a highly adaptable DC 7~36V wide voltage power supply and housed in a sturdy, stackable 35mm DIN rail-mount enclosure, this analog output module is the ideal choice for industrial automation, sensor calibration, and PLC control systems requiring dependable, high-fidelity signal conversion.
Features:
- Cascade several devices on the RS485 bus with configurable device addresses (1-255).
- Onboard voltage regulator supports 7-36V power supply.
- Onboard unibody power supply separation delivers stable isolated voltage and does not require an additional power source for the isolated terminal.
- Onboard unibody magnetic isolation provides signal separation, great dependability, and powerful anti-interference.
- Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, providing over-current/over-voltage proof, lightningproof, and anti-electrostatic
- 12-bit DA conversion using high-precision resistors for more precise output data.
- Onboard watchdog ensures consistent output without crashing.
- Rail-mount case design, supports stacking combinations, is simple to install and safer to use.
- 3x LEDs to indicate the MCU and signal transceiving status.
