Programmable Logic Controller SPDs

APS LLC | Programmable Logic Controller Surge Protectors

For PLC protection, use high quality, high performance Programmable Logic Controller surge protectors. These unique SPDs provide Full Spectrum ProtectionTM 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 and other types of equipment 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 address RingWave surges effectively. This includes surge protectors with EMI/RFI Technology. Our SPDs do.

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

Our SPDs are specifically built to perform in all modes against both Impulse and RingWave Transients. This technology design leads the industry. This is Full Spectrum ProtectionTM.

RingWave Surges Cause Damage To PLCs

RTUs, PLCs, CNC Machines, and other computing systems can be disrupted and damaged by RingWave surges. Most RingWaves get past standard surge protector fixed clamping protection. Fixed clamping circuitry is not designed to mitigate RingWave transients. It's designed for impulse transients. EMI/RFI circuitry is not designed for RingWave transient protection either.

A SPD with both Fixed-Clamping and EMI/RFI Technology only amounts to Partial Protection. System disrupts and damage can still occur.

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. Reduce system disrupts and damage with Full Spectrum ProtectionTM applications!
