Ordering designation

Digital measuring device IP-7-TKХXХDYY:

ХXХ – supply voltage variants:

«24V» – 24 VDC;

no marking – 220 VAC 50Hz;

DYY – sensor supply voltage:

«YY» – stabilized voltage taken by a customer from  a range (2..48) VDC, measuring circuit is galvanically isolated from a sensor supply circuit;

no marking –unstabilized (18..36)VDC, no power isolation between measuring circuit and sensor supply circuit.

Example. Digital measuring device IP-7-TK-24V-D36 – digital measuring device with 24VDC supply voltage, 36VDC stabilized sensor supply voltage.
