SLP Communication Lines Surge Protection

Surge protect low voltage communication lines for HVAC, thermostats, pool controls, security, irrigation systems, and 4-20mA current loops with TPD products. Control wires between systems are pathways for surge events to enter and leave the system traveling to other equipment when left unprotected. Protect sophisticated equipment by using the TPD-SLP series on copper pathways entering or leaving the facility and between systems that have had damage.
