For the compact versions, the intrinsically safe flow sensor circuits are designed as internal
circuits.
For the remote versions, the intrinsically safe flow sensor circuits are led through. The
maximum permissible safety values of the flow sensor circuits are listed below:
Remote signal converter, flow sensor circuit (terminal 1 to 7, colour-coded) Remote signal converter, flow sensor circuit (terminal 1 to 7, colour-coded)

INFORMATION!
The verification of intrinsic safety for the interconnection between the flow sensor an the signal
converter is not necessary, if the cable length does not exceed 50 m / 164 ft and the supplied
cable is used.
