Switching Head

A-V2

Switching Head A-V2     For devices VM-

●I M1 Ex ia Ma
●II 1G Ex ia IIC T4 Ga
●II 1D Ex ia IIIC T135°C Da

Intrinsically safe switching head with reed switch and ATEX approval, for the VM range of devices, for use in intrinsically safe power circuits.

Handling and operation
Note
●For use only in intrinsically safe power circuits; provide a suitable isolating amplifier.
●Cable lengths max. 5 m.
●It must be ensured that the values given for voltage, current, and power are not exceeded.
●When switched on, a load must be connected in series.
●The electrical details apply to ohmic loads. Capacitive, inductive and lamp loads must be operated using a protective circuit.


Adjustment
To adjust the switching point, the fixing screw for the switching
head must be loosened. The switching head can then be rotated.
