GTL-842 Over current protection relay

Over current protection relay: 1.4U standard aluminum chassis 2.CPU intelligent card design 3.Plug-in based on CANBUS bus

  GTL-842 Over current protection relay

The device chassis structure adopts the standard all-aluminum PC cases as trunk,whose height is 4U,

 length is divided into half and full chest, where the length of the full chest is 19 inches, and it has the same size as full chest when two half chests are piece together. Its appearance is not only beauty but also beneficial to group screen. GTL-84(2X) series adopts the entire panel, including LCD panel, signal light, keyboard, corporate identity and so on.Device unit 

chassis is reinforced and designed by strong anti-vibration and antiinterference, which ensure that it is still high reliable 

installed in the harsh conditions.

It is not required to add AC and DC input interference module whether installed distributed or by groups.

 Features:

Dual-CPU and redundancy system.16 AD sampling and high precision. Wave 48 sampling points per week, powerful filtering capabilities.Intelligent multi-plug CPU design.Open out into the plug-in real time to achieve full self-test and self test function of real time components.Complete circuit breaker operation, with remote control, anti-jump, pressure latch functions.LCD interface editingSupport 192 × 64 large-screen LCD blue and 4.3' color LCD
