Biodigester Micro-CHP Controller

Introduction

A Biodigester Micro-CHP Controller needs strong hardware. The Moduline L4 offers stable control in rough field environments.

Reliable control for clean energy units

A Biodigester Micro-CHP Controller must run day and night. It has to manage heat, power and safety while the biodigester produces gas. Because these systems often sit in farms or small industrial sites, the controller must handle weather, vibration and long service hours.
The GOcontroll Moduline L4 fits this need. It has a strong aluminium housing, flexible IO modules and a powerful processor for real-time control. As a result, the controller works well for managing pumps, valves, sensors and generator units inside a micro-CHP setup. It also offers easy software tools, which help teams adjust the control system quickly.

Why the Moduline L4 fits biodigester CHP

Flexible IO for biodigester processes

A Biodigester Micro-CHP Controller needs many sensor types. The Moduline L4 supports up to eight Moduline IO modules, which helps engineers create the exact setup they need.
These modules can measure or control:

• Gas temperature
• Gas pressure
• CH₄ sensors
• Pump control signals
• Valve outputs
• Generator status lines

The Input Modules support analog, digital and frequency inputs, while output modules handle up to 4 A per pin. This makes it possible to drive small actuators or send signals to external power stages. The modules connect through sealed automotive connectors, so wiring stays protected from dust and moisture.

Real-time control with Simulink and Node-RED

Strong communication options

A Biodigester Micro-CHP Controller often sits away from the main building. Because of this, stable communication helps operators respond to problems quickly.
The Moduline L4 includes:

• 4 CAN 2.0B interfaces
• 1 LIN interface
• Ethernet (10/100 Mbps)
• USB for local tools

Optional features include Wi-Fi, Bluetooth, cellular and GNSS. These options allow the system to send logs or alarms to service teams. GOcontroll’s remote services support secure access, software updates, and predictive maintenance. This is useful for sites that run 24/7 and cannot afford downtime.

Example Micro-CHP control workflow

Below is a simple workflow for using the Moduline L4 as a Biodigester Micro-CHP Controller:

Input stage

Temperature, pressure and flow sensors send their values to the input module. The controller reads these signals at a steady rate.

Control stage

A Simulink model calculates gas quality, burner needs and generator load. It adjusts valves and pumps through output modules.

Safety stage

The model checks gas levels, ignition status and temperature limits. If something goes wrong, the controller can shut down parts of the system.

Monitoring stage

Node-RED or a local HMI shows the system state. Operators can see heat output, gas production and energy flow.

Remote support

With optional wireless hardware, data can go to a cloud dashboard. This helps maintenance teams track system health and plan service.
