What Is the K9 Pig Farm Environmental Controller?
The K9 is an entry-level pig house environmental controller developed for farms where temperature, ventilation and evaporative cooling are the main control requirements.
It can collect temperature and environmental sensor data and automatically control fans, cooling pads, heaters and air inlets according to configured parameters.
Unlike higher-capacity controllers, the K9 focuses on the input and output points commonly required in a single pig barn or a small number of barns, helping reduce unnecessary system cost.
Where Is the K9 Suitable?
The K9 is suitable for:
Small and medium-sized pig farms;
A single pig barn or a small number of barns;
Conventional negative-pressure ventilation;
Fixed-speed and transverse ventilation fans;
Variable-frequency fans using compatible 0-10V control;
Evaporative cooling pad systems;
Basic heating and air inlet control;
Farms without complex air filtration systems.
It can be applied in nursery barns, finishing barns, sow barns and other conventional pig housing projects according to the actual equipment configuration.
Pig Barn Temperature and Sensor Monitoring
The K9 provides 3 temperature sensor inputs for monitoring different areas inside the pig barn.
It also includes 2 channels of 4-20mA inputs, which can connect compatible environmental transmitters such as:
Humidity sensors;
CO₂ sensors;
NH₃ sensors;
Pressure sensors;
Other 4-20mA environmental sensors.
Environmental data can then be used as the basis for automatic ventilation and cooling control.
Fan and Ventilation Control
The K9 includes 9 relay outputs and 3 channels of 0-10V analog outputs.
According to project requirements, outputs can be configured for equipment such as:
Fixed-speed fans;
Transverse fans;
Variable-frequency fans;
Cooling pads;
Air windows;
Small air inlets;
Heaters;
Alarm outputs.
According to the product configuration, the K9 can support control schemes involving up to 8 fixed-speed fans, 8 transverse fans, 3 variable-frequency fan channels, 8 cooling pad groups, 1 air window, 3 small windows, 8 heating groups and 1 alarm channel.
The actual number of devices that can be controlled simultaneously depends on the available relay outputs, analog outputs and wiring configuration.
Evaporative Cooling and Ventilation Coordination
Evaporative cooling performance depends on both cooling pad operation and sufficient airflow through the pig barn.
If cooling pads operate without adequate ventilation, indoor humidity may increase while the actual cooling effect remains limited.
The K9 therefore provides ventilation compensation control, allowing ventilation and evaporative cooling to work together according to the control logic.
This makes the K9 suitable for pig barns using cooling pads and negative-pressure exhaust fans, especially in hot-weather conditions.
Flexible Output Configuration
Different pig farms use different combinations of fans, cooling pads, heaters and air inlets.
The K9 allows relay and analog output channels to be configured according to the connected equipment instead of using completely fixed channel assignments.
This provides greater flexibility for pig farm owners, livestock equipment suppliers and system integrators when configuring different barn projects.
Data Upload to AiFarm
The K9 supports built-in or external 4G or Ethernet IoT modules.
Operating and environmental data can be uploaded to the AiFarm digital platform for remote monitoring and data management.
An optional RS485 interface can also be used to collect data such as:
Water consumption;
Electricity consumption;
Feed consumption.
This allows farms to combine environmental control with basic production and resource consumption monitoring.
Simple and Reliable Keypad Operation
The K9 uses a 3.6-inch physical keypad display.
For pig barn environments with dust and humidity, keypad operation provides a simple and reliable way to:
View environmental parameters;
Set temperature targets;
Adjust ventilation settings;
Configure cooling functions;
Check equipment operation.
The interface is designed for projects where equipment configurations are relatively fixed and daily parameter adjustment is limited.
Does the K9 Support Digital Fans or EC Fans?
The K9 is mainly designed for conventional relay and analog fan control.
It does not support communication-based digital fan group control, individual fan status feedback or digital fan communication speed regulation.
For pig barns using digital fans or EC fans that require communication-based control, CCSDA digital fan controllers such as the D60 or D1000 should be considered.
Does the K9 Support Positive-Pressure Ventilation?
No.
The K9 is designed for negative-pressure ventilation systems.
Projects involving positive-pressure ventilation, combined positive-negative pressure ventilation, air filtration or more complex ventilation strategies require a higher-level controller selected according to the project design.
