## Summary description

Ropam PMT is a phase presence controller designed to monitor the presence of electrical phase and provide an OC (open-collector) output with galvanic isolation. It detects phase availability and signals via the isolated output for use in protection, control and automation systems. Suitable for integration into alarm panels, energy monitoring and industrial control where phase detection and safe signal transmission are required.

## Long description

Ropam PMT is a controller for detecting the presence of an electrical phase and providing an OC (open-collector) output with galvanic isolation. The device continuously monitors whether a phase is available and transmits a corresponding isolated signal to downstream systems. Designed for straightforward integration, the controller is intended for use in protection, control and automation installations where reliable phase detection and electrically safe signaling are required.
Advantages
The Ropam PMT provides galvanic separation between the monitored mains phase and the output, reducing the risk of interference and ensuring safe signal transfer to sensitive control equipment. The open-collector output delivers a simple, compatible interface for a wide range of monitoring and alarm panels. Compact design and clear function eliminate the need for complex configuration while maintaining continuous phase supervision.
Suitable for
Integration with alarm and security control panels for phase-loss detection
Energy monitoring systems that require confirmation of phase presence
Industrial automation and control cabinets needing isolated phase signals
Protection circuits where galvanic separation between mains and logic inputs is mandatory
Key specifications
Function: single-phase presence detection
Output type: open-collector (OC) with galvanic isolation
Signal compatibility: suitable for TTL/logic level inputs or relay driver stages (via appropriate pull-up)
Mounting: DIN-rail or panel-mount compatible form factor (compact footprint)
Operating principle: continuous phase monitoring with immediate output change on phase loss or restoration
How to use
Install the controller in the electrical cabinet according to wiring guidelines, connecting the monitored phase conductor to the device input and routing the OC output to the control, alarm or monitoring input that accepts open-collector signals. Provide an appropriate supply and common reference where required by the receiving equipment. Verify correct operation by simulating phase loss and restoration and observing the isolated output response.
Usage recommendations
Use Ropam PMT in systems where galvanic separation improves safety and reduces interference risk. Ensure the receiving device provides a proper pull-up resistor or input reference compatible with an open-collector output. Follow local electrical regulations and standard installation practices when working with mains connections and consult product documentation for detailed wiring limits and environmental conditions.
