GMI D9520S Surge protection for I/O signals and Signaling Surge Arresters

DESCRIPTION

D9520S provides two-stage surge protection for floating I/0 three wires signals of measurement and control and safety systems. With width of 6mm, it can be easily fitted into any marshalling cabinets or distribution cabinets. It consist of a protective plug and a base element. The SPD provides surge protection with 1.65Ω loop impedance, with disconnect knife on both signal paths for easy testing of the loop.

FEATURES

SIL 3 according to IEC 61508:2010.

Input from Zone 0 (Zone 20), installation in Zone 1 and 2.

Disconnection of signal circuit by disconnect knife.

Signaling without additional auxiliary power, thanks to the mechanical status indicator.

Signal not interrupted during maintenance work, thanks to impedance neutral insertion and removal of protective plug.
