CITEL DLATS Series – DIN Rail Surge Protection with Remote Monitoring for Data and Telecom Lines
Type 2 SPD | Pluggable 1-Pair Protection | Remote Signaling | IEC/EN 61643-21 Compliant
The CITEL DLATS Series offers advanced surge protection solutions for data communication and telecommunication lines, combining robust protection with remote monitoring capabilities. Designed for DIN rail mounting, the DLATS series is ideal for safeguarding sensitive equipment connected to industrial buses, telecom lines, or data lines against transient overvoltages caused by lightning or switching events.
Each module provides 1-pair protection and features a pluggable design for easy maintenance and replacement. The series incorporates a remote signaling function through an optional control module, enabling centralised monitoring of up to 48 SPD modules. This feature allows for prompt detection and response to SPD status changes, enhancing system reliability and uptime.
