Industrial Modbus RTU 8-Ch Analog Output Module 12-bit DA (Output 0~10V) - Waveshare 26211

Features at a glance

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.

1. Configurable device address (1~255), multi devices can be cascaded on RS485 bus

2. Onboard voltage regulator, supports 7~36V wide range power supply

3. Onboard unibody power supply isolation, provides stable isolated voltage, needs no extra power supply for the isolated terminal

4. Onboard unibody magnetical isolation, allows signal isolation, high reliability, strong anti-interference

5. Onboard resettable fuse and TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, provides over-current/over-voltage proof, lightningproof & anti-electrostatic

6. 12-bit DA conversion, using high-precision resistors for more accurate output data

7. Onboard watchdog, for stable output without crashing

8. Rail-mount case design, support stacking combination, easy to install and safer to use

9. 3x LEDs for indicating the MCU status and signal transceiving status

Specifications

Primary function

Supports sending Modbus RTU protocol commands via RS485 and outputing data to 0~10V or 0~20mA sensor

Industrial Grade Isolated Protection

Onboard power and signal dual isolation for RS485 communication, provides stable isolation voltage, features high reliability and strong anti-interference performance. Built-in TVS (transient voltage suppression tube) can effectively suppress the surge voltage and transient peak voltage in the circuit, lightningproof & ESD protection. Built-in resettable fuse and protection diode to ensure stable current and voltage output, provides over-current and over-voltage proof, improves shock-proof performance, suitable for industrial environments with high requirement.

Note: The internal component layout is slightly different between the two versions, please refer to the actual product
