RS422 circuit 15V DC signal SPD surge protector

SPD FS-DR-15/4.1 is for CCTV protection Un DC15V, Imax 10kA.

1. Surge protection device Characteristic for FS-DR-15/4.1

- Din rail data surge protection device are applied to control signal double wire circuit in LPZ0 to LPZ3, e.g. 4~20mA circuit, RS485 circuit, RS422 circuit, gas detector, car-park system, CCTV remote monitor, remote control circuits.
- Common and difference surge protection mode, excellent performance.
- The pluggable module allows a fast replacement in case of fail.
- The grounding is realized through an earthing-clip on the DIN-Rail and / or earthing - clamp.
- No limiting in operating current due to parallel connecting method.
- Mounting on 35mm Rail, small space.
-Un 15Vdc, Uc 17.8Vdc
