SALTEK DMG-024-V/1-4FR1-DIF SPD – Data, Signalling and Telecommunication

Pluggable module, coupling impedance (R – resistance), shielding (G) separated from protective earth via GDT.

Coarse and fine surge protection for max. 4-core signalling lines.
Installation close to protected equipment.
For protection of communication interfaces of I <(>&<)>C, electronic security and fire detection systems, etc. (mainly for RS-485 interfaces) against impact of surge voltage.
Coarse and fine surge protection only in differential mode (core – core).
