What is it?
The Sensitron PL4+ is a compact and reliable gas detection controller, specially designed for monitoring toxic and combustible gases in industrial environments. The system supports multiple gas detectors and features flexible configuration options with a clear LCD display for easy operation. Thanks to programmable relay outputs and communication options such as Modbus, the PL4+ can be seamlessly integrated into existing safety and building management systems.

How does it work?
The PL4+ processes signals from connected gas detectors and continuously monitors gas concentrations. Each detector can be individually configured with alarm thresholds and response times. Upon detecting hazardous gas levels, the system immediately triggers visual and audible alarms and activates relay outputs to control ventilation or emergency systems. Communication with other systems is handled via Modbus RTU/RS-485, while built-in self-tests and fault notifications ensure reliable operation.

What problems does it solve?
In industrial settings, fast and reliable detection of gas leaks is crucial to prevent accidents, environmental damage, and equipment harm. The PL4+ provides an efficient and scalable solution that enhances the safety of personnel and facilities. By centralizing monitoring and delivering timely warnings, the system helps reduce risks and ensures compliance with safety standards.
