Without question, the main complaint in the industry with regard to lightning surge protectors is the difficulty in determining whether the surge or lightning protector installed to protect your control system components is still functional.

Modern day industrial equipment relies heavily on microprocessor-based technology. This makes it essential for critical control components to be protected from lightning, transients and surges.
The lightning surge protectors with health indication operate by monitoring the leakage current from signal to earth ground. Additionally the number of suppressed surges is also monitored. When a predetermined level of either the leakage current or number of suppressed surges is exceeded, the health indicator illuminates.

Low in cost, these devices pay for themselves by providing early warning alarms and reducing ongoing unnecessary panel maintenance. To give you an idea of their functionality, consider opening a panel with a large number of lightning surge protectors. Instead of unplugging and testing every unit, for our life monitor series all that is necessary is a quick visual indication. No further tools or checking are required!

When it comes to comparing the cost of downtime versus lightning surge protector replacement, the choice is obvious.
