ST2+3 (DM) - plugable
DMG-024-V/1-4FR1-DIF
Order number: A06281
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)
