- AC/DC converter 220VAC/24VDC (if 24VDC supply voltage variant is choosed).
Ordering designation
Digital measuring device IP-7-TK–ХXХ–DYY:
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.
