1 INTRODUCTION

The Ex-proof modules have been designed for powering and signal conversion of intrinsic safe meters.

Furthermore a valve drive circuit may be incorporated in the system. The output stage for the valve can,

depending on the limits of the valve also be made intrinsically safe by using an isolating repeater. Without

isolating repeater a valve with “II 2 G (ATEX group and category) - Ex e mb II T4” (Cenelec) classification can

be powered. With isolating repeater a valve with ” II 1 G/D (ATEX group and category) - Ex ia IIC T6” (Cenelec)

classification can be powered.

Note: Readout units with its I.S. isolators should be situated outside zone 2.
