The surge protection device PT-IQ-2X2+F-48DC-UT incorporates a protective plug and base element to ensure the safety of two 2-wire floating signal circuits. It is equipped with an integrated multi-stage status indicator, allowing for clear monitoring of operational status. The device achieves indirect grounding through a gas-filled surge arrester, enhancing protection against voltage surges.

Connecting this module is straightforward; it snaps into place on a DIN rail connector, which also facilitates remote signaling and power supply management. The dimensions of this device are 91.1 mm in height, 17.7 mm in width, and a depth of 77.5 mm, including a DIN rail of 7.5 mm, with a horizontal pitch of 1 Div.

For connectivity, it employs a screw connection method with M3 screw threads, requiring a tightening torque of 0.5 Nm. The stripping length is 8 mm, accommodating flexible conductors with cross-sections ranging from 0.2 mm² to 2.5 mm² and solid conductors from 0.2 mm² to 4 mm², as well as AWG sizes from 24 to 12.

This device operates effectively within an ambient temperature range of -40 °C to 70 °C and can be stored or transported at temperatures between -40 °C and 85 °C, suitable for altitudes up to 4000 m above mean sea level. It is rated with IP20 protection, ensuring adequate safety against foreign objects.

In terms of surge protection capabilities, it conforms to IEC test classifications C1 through D1, with a nominal voltage of 48 V DC. The maximum continuous voltage is 53...
