Current supply units:Intrinsically safe power supply units can bechoosen in a list of compatibility inwww.norgren.com

When selecting an intrinsically safe power supply, it is

important to observe the maximum permissible values

acc. to the EC-Type-Examination Certificate

PTB 04 ATEX 2010

U0 28 V, L0 110 mA, P0 1,5 W

The effective internal capacities Ci; and inductivities

Li of the solenoid are negligibly low.

Function of solenoid driveTo switch the direct operated valve, a certain energy is

required. This energy is stored in a condenser.

The charging voltage is 22 V. The higher the supply

voltage, the shorter the charging time. As soon as the

charging voltage has been reached, the valve switches.

The small current now flowing through the coil is

sufficient to hold the valve in the open position.

At least 40 mA are required for this.
