At the end of this year SALTEK® is introducing a new line of SPDs for data, signaling and telecommunication networks in screwless terminal blocks.

They are suitable mainly for industrial applications for protection of single- and two-core measuring and signaling lines of I&C, electronic security and fire alarm systems, etc. Using of these SPDs increases lifetime and failure-free operation of connected devices. Moreover, in installations with multiple lines they significantly saving the space in the distribution board thanks to their 6 mm width only (without the side cover, which is in the scope of delivery for each piece).

A full range of these data SPDs (types DM, DMG, DMJ, DMHF, DMLF and DS) in terminal blocks with screwless terminals for easy wire’s connection with nominal voltage from 6 to 48 V DC and nominal current up to 0.5 A. Such devices will be used typically for surge protection of RS-485 bus, binary inputs and outputs, current loop 0(4) ÷ 20 mA or telephone and high-frequency xDSL lines. There is even available version DMLF for low-speed lines used in the areas with RFI.

The same variants of terminal blocks are offered also in version with screw terminals as D...-RS. More information and all SPDs SALTEK® you can find in on-line catalogue.
