Surge protection with integrated status indicator and disconnect knife for a 2-wire floating Ex i signal circuit, e.g.,
0(4) ... 20 mA current loop, HART-compatible.
Your advantages
Space-saving and inexpensive with a narrow overall width of just 6.2 mm
Signaling without additional auxiliary power, thanks to the mechanical status indicator
Optional remote signaling module monitors up to 40 items, without additional wiring
Signal circuits easily interrupted for maintenance work, thanks to vertical knife disconnection
Safe behavior in the event of overload, thanks to the integrated disconnect device
