Surge Protection Device

Description

Phoenix Contact has introduced PT-IQ: an intelligent MCR surge protection device with multi-stage remote monitoring. It provides proactive functional monitoring for signal interface surge protection devices. The system informs the user if a plug replacement is needed long before the components fail due to overload. This can prevent unnecessary service costs, while ensuring system availability and signal quality. 

The device’s multi-stage/three-stage monitoring system enables fast and clear status identification. A yellow signal indicates that the performance limit has been reached as a result of frequent surge voltages, while a small reserve capacity ensures that protection remains effective. A red signal indicates failure. A controller monitors and sends status reports back to the control room where users can inspect the system. PT-IQ features impedance-neutral plugging, insulation measurement without disconnection and a snap-lock mechanism for easy plugging and unplugging. 

In addition, the PT-IQ’s T-bus connection provides reliable power and data transmission, easy and error-free installation and automatic integration of SPDs without wiring. PT-IQ provides protection for up to five signal wires and is available in floating and directly grounded shield connections. One power terminal block powers 28 SPDs, reducing installation cost.
