DKU with three-stageovervoltage protection
The three-stage overvoltage protection terminals are fitted with gas discharge tubes, varistors, suppression diodes (TAZ) and decoupling inductors. The gas discharge tubes divert high currents reliably. Varistors and suppression diodes take up the residual voltages. The rated current is up to 300 mA for models DK4U and DK5U and up to 1 A for model DK6U.
The DKU series consists of (6mm wide, DK4U (12mm wide), DK5U (6mm wide and DK6U (8mm wide).
The DKU and DK5U are available for mounting rail TS32 or TS35. The DK5U and DK6U have a combined foot.
Applications include current loops 0(4) to 20mA and 0 to 10 V signals
