High Performance Programmable
Logic Controller SPDs

For PLC protection, use high quality, high performance Programmable Logic Controller surge protectors. These unique SPDs provide Full Spectrum Protection for critical and sensitive process control systems.

Today, all circuit-designed equipment is susceptible to transient voltage. Microchips can be damaged by sudden large surges or by constant, repetitive low level surges.

Programmable Logic Controllers are increasingly at risk as process control systems become more demanding in today's commercial and industrial environments.

Programmable Logic Controller SPDs Should Defend Against
Two Distinct Types of Surge Damage. Many Don't. Ours Do.

Electric Motors, drives, compressors, printers and other types of electronics produce damaging transients. These transients are called RingWaves. RingWaves are frequency based and are as damaging over time as the more familiar over-voltage impulse type surges.

Important Note: Few surge protectors truly address RingWave surges effectively. This includes surge protectors with EMI/RFI Filtration Technology.

Critical and sensitive equipment, especially complex PLC systems, need surge protectors that defend against both Impulse and RingWave power surges.

Many SPDs don't provide High Quality RingWave suppression technology. Our SPDs do. Our devices lead the industry with Full Spectrum Protection.

RingWave Surges Cause Serious Damage To PLCs

RTUs, PLCs, CNC Machines, and other computer operating systems are being damaged by RingWaves. Most RingWaves get past a standard surge protectors impulse or fixed clamping protection circuitry.

Fixed clamping circuitry is not designed to mitigate RingWave transients. Fixed Clamping is designed primarily for impulse type transients. EMI/RFI circuitry is not designed for effective RingWave transient protection either.

A SPD with both Fixed-Clamping and EMI/RFI circuitry only amounts to Partial Protection.

20% of surge related damage is caused by External sources. 80% of surge related electrical damage is caused by Internal sources. Most Internal surge activity are RingWaves.

Don't settle for partial or 20% protection when Full Spectrum Protection is available!
