Description
8-channel 4–20 mA analog output module that sends control signals from the Q-Controller to other devices
The QEL AO-BOX-0 lets your Q-Controller do more than just monitor gas levels. It also lets it control other equipment using standard 4–20 mA control signals. Each module adds eight analog outputs that can feed drives, PLCs, BAS inputs, or other control devices, so you can tie fan speeds, damper positions, or other building functions directly to gas readings and system logic.
Because the AO-BOX shares the same 2-wire RS-485 network as the other Q-Controller modules, you can drop it where it makes sense in the panel and still configure everything from the Q-Controller touchscreen. Up to 16 AO-BOX modules can be used on a single Q-Controller, giving you as many as 128 analog outputs for large garages, plants, and multi-zone facilities that need more than simple on/off control.
Key Features & Benefits
Turn Gas Readings into Real Control
Converts Q-Controller decisions into 4–20 mA control signals, so VFDs, BAS controllers, and other devices can automatically ramp fans, open dampers, or adjust ventilation based on gas levels.
Easy Expansion for Larger Jobs
Each AO-BOX adds eight analog outputs; with up to 16 modules on one Q-Controller, you can support 128 control signals on a single system, giving you plenty of room for future zones or added equipment.
Keeps Wiring and Setup Simple
Uses the same RS-485 2-wire communication loop as the other Q-Controller I/O modules, so you can daisy-chain devices instead of running dedicated homeruns for every point.
Fast Replacement with Stored Settings
All configuration is stored in the Q-Controller and each module keeps its own 4–20 mA calibration data, so a replacement AO-BOX with the same address drops in without reprogramming or recalibrating.
Panel-Friendly Design
High-density packaging, removable terminal blocks, and DIN-rail mounting help save panel space and make wiring and service work faster.
