D9510S

D9510S provides two-stage surge protection for floating I/0 two 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.

• 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.
• High Density, 6.2 mm per channel.
• HART compatible.
