This product is designed for monitoring the speed of two PWM fans. If the set minimum speed is undershot for example contamination or a fan failure corresponding signal and LED outputs are activated, which can be evaluated externally. Using a potentiometer, the maximum speed of both fans can be adjusted. A customized software adjustment, for example changing the minimum speed threshold, can be optionally offered by us.

Typical Application Areas:
- Monitoring of industrial cooling systems:
The module is suitable for reliable monitoring of fan systems in control cabinets, machines, and industrial installations. It detects deviations in rotational speed at an early stage and ensures operational safety. - Condition monitoring of system fans:
The ZBH-FAN-CONTROL-2CH is ideally suited for continuous monitoring of two fans in technical systems. Speed deviations or standstill are detected and signaled immediately. - Fail-safe protection for critical electronics:
Perfect for applications where stable cooling is critical. In the event of fan failure or under-speed conditions, external protective measures can be triggered immediately. - Machine and system monitoring:
The module is used in machines to monitor fan status in real time, helping to prevent overheating of components. - Computing and control systems in industrial environments:
The ZBH-FAN-CONTROL-2CH is suitable for monitoring fans in industrial PCs, controllers, or embedded systems to ensure thermal stability. - Control cabinet and infrastructure monitoring:
Ideal for use in control cabinets, server environments, or technical infrastructures where constant cooling is required.
