MODBUS AO1012 12 channel analog 0-10V output module - multi-channel dimming/speed regulation/valve control/HA centralized control

Product Overview

MODBUS AO1012 (HAAO1012)is a12 channel independent 0-10V analog outputmodule, each of which can output a 0-10V voltage signal with an accuracy of ± 1%. The 12 channels are completely independent and do not interfere with each other. One module can simultaneously drive up to 12 0-10V LED dimming drivers, 12 EC fan speed controllers, or 12 proportional control valves. Using RS485 Modbus RTU communication and centralized control through Home Assistant or PLC. Built in overcurrent/overvoltage/anti reverse/anti lightning surge protection, industrial grade reliability. Why choose route 12? In commercial lighting engineering, a large space may be divided into 12 dimming zones; In agricultural facilities, 12 fans require independent speed regulation. The traditional solution requires 12 independent dimming modules, with extremely high wiring complexity and management difficulty. AO1012 integrates 12 channels into one DIN module, and RS485 can control all 12 channels with one bus (Zigzag connection).

Core Parameters

• Output: 12 independent 0-10V channels, accuracy ± 1%
• Resolution: 12 bit DAC, 4096 levels (0.0024V steps per channel)
• Protection: overcurrent/overvoltage/anti reverse/anti lightning surge
• Communication: RS485 Modbus RTU
• Power supply: DC 12-24V
• Installation: DIN rail

Modbus control

12 voltage values are mapped to 12 consecutive hold registers (0x0000-0x000B), with a range of 0x0000-0x0FFF (0-4095 corresponds to 0-10V). Use function code 16 (write multiple registers) to write all 12 voltage values at once, with millisecond response.

Application Scenarios

• Exhibition hall lighting: Independent dimming of lighting zones in 12 exhibition areas
• agricultural greenhouse12 circulating fans with independent speed regulation
• Building HVAC12 proportional control valves synchronized or independently controlled
