PM5-PAD

Panel Indicators, Pilot Lights

Paper Mied beacons (PM5) have been a leading choice for providing reliable warning and indication for a range of industries for years. PM5-PAD are part of the latest generation PAD series of beacons, designed to enhance the levels of reliability and performance. This article outlines the application fields and working principle of PM5-PAD.

Application fields

PM5-PAD beacons are specifically designed to meet the needs of the oil and gas, power generation, water and wastewater industries. Typical applications for PM5-PAD beacons include:

• Water tank level indication
• Pump monitoring
• Diesel oil storage/ tank filling
• Fire and gas system alarms
• Leakage detection
• Door and window access control
• Fuse isolation indication
• Status indication in communications systems

In addition to providing reliable warning and indication PM5-PAD beacons are also designed to be more cost effective and offer better tamper protection than previous generations. These benefits are only a few of the reasons why PM5-PAD are a popular choice for industrial applications.

Working Principle

PM5-PAD beacons operate by sensing a relay or contact closure when they are in the locked (on) position. When the power supply is applied, an internal micro-switch starts a countdown timer to detect the presence of the external input contact closure. If no external input is detected, the beacon will revert to the standby mode.

When the external input contact closure is detected, the solid-state relay is energised and the beacon is triggered. The solid-state relay prevents arcing and sparks generated during switching. The LED light source provides a bright and reliable indication even in harsh weather conditions. In addition, the housing is designed to withstand temperatures ranging from -20°C to +65°C.

Conclusion

PM5-PAD beacons provide reliable indication and warning signals in a range of industries. The beacons are designed to be more cost effective and offer higher levels of tamper protection than other models. The working principle of PM5-PAD beacons is based on a solid-state relay and a LED light source, making them suitable for use in a range of harsh environmental conditions.
