Universal DIN-Rail Surge Arrestor (D9510S)
The D9510S modules provide two-stage, SIL 3 surge protection for floating I/O signals used in control and safety systems. Its slim 6 mm profile allows it to fit easily into marshalling or distribution cabinets, saving space and reducing installation costs. With disconnect knives on both signal paths, loop testing becomes straightforward and hassle-free.
Features:
- SIL 3 Certified (IEC 61508:2010 Ed.2).
- Input from Zone 0 (Zone 20); installation possible in Zones 1 and 2.
- Hot removable plug module available in the D9500 version.
- Protection for floating double-wire systems in intrinsically safe circuits.
- High-density design (6.2 mm per channel) with HART compatibility.
Cartridge & Fault Indication Surge Arrestor (D9400/D9500)
Providing SIL 3 surge protection for floating I/O signal circuits, the D9400/D9500 series comes in a compact form factor with an optional pluggable cartridge. The module includes a local and remote fault indication system, notifying you immediately of disconnection without needing an auxiliary power supply. A remote indication set is available for monitoring up to 40 modules simultaneously. Certified for use in IS loops, it is ideal for hazardous area installations.
