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

●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.
Turning to the right increases the switching point, and vice-versa.
Then retighten the fixing screw.

Ordering code

The base device is ordered, e.g. VD-015GR020A with switching head e.g. A-V1-1.
