Surge protection for power supply and analogue signal lines in pipeline monitoring systems.
The HDTNV1/48C protects one pair of lines against surge effects. Its pluggable module combines two protection stages and provides galvanic isolation between the protective earth and shield terminals.
It is suitable for 4–20 mA analogue current loops and system power supply lines. Selection for gas installations and cathodic protection monitoring depends on the electrical circuit and installation requirements.
Rated voltage: 48 V DC · Rated load current: 1.5 A · Protection: IP20 · Mounting: 35 mm DIN rail. This model is not intended for high-speed digital data transmission.
