The PT-IQ-4X1+F-24DC-UT surge protection device is designed to safeguard signal transmission by utilizing an indirect grounding mechanism through a gas-filled surge arrester. This device incorporates a multi-stage optical status indicator, enabling real-time monitoring of the operational status across four signal wires that maintain a common reference potential.

Constructed as a two-section DIN rail module, it measures 17.7 mm in width, 91.1 mm in height, and 77.5 mm in depth, accommodating installation within a standard 35 mm DIN rail. The device operates at a nominal voltage of 24 V DC and is rated for a maximum continuous operating voltage of 30 V DC. Its rated current capacity is 700 mA at an ambient temperature of 50 °C.

With a pollution degree of 2 and an overvoltage category of III, the surge protection device ensures compatibility with a variety of industrial applications. The unit supports screw connections, allowing for conductor cross-sections ranging from 0.2 mm² to 4 mm² for rigid conductors, and 0.2 mm² to 2.5 mm² for flexible conductors, with a tightening torque of 0.5 Nm.

In terms of surge protection capabilities, the device can handle a nominal discharge current of 10 kA and a total discharge current of 20 kA under specified conditions. The voltage protection level against line-to-earth surges is ≤ 800 V, while the static level is ≤ 80 V. It also exhibits a rapid response time of ≤ 100 ns, ensuring minimal disruption during transient events.
