DITEK DTK-DR24B Low Voltage DIN Rail Surge Protector for 24V circuit pairs

Protect mission-critical low-voltage security and surveillance systems from damaging transients with the DITEK DTK-DR24B DIN-rail surge protector. This low-voltage surge protection module is engineered to safeguard two 24V circuit pairs commonly used in CCTV, access control, fire alarm and monitoring installations. The compact 35mm DIN-rail mounting simplifies integration into equipment racks and enclosures while the field-replaceable protection module reduces service time and ongoing maintenance costs. A hybrid SAD and GDT design delivers high-performance clamping and a fail-safe short-to-ground mode if the device becomes compromised, giving installers and facility managers added confidence. Designed for both AC and DC low-voltage applications, the DTK-DR24B is TAA/NDAA and RoHS compliant and backed by a 10-year limited warranty. Ideal for integrators and IT/security teams specifying robust, code-compliant surge protection for networking, surveillance and monitoring systems—add the DTK-DR24B to your next deployment to protect critical equipment and minimize downtime.
