Exi chart recorder ExTrend 200i
The intrinsically safe videographic recorder ExTrend 200i is designed for the visualisation of processes inside the hazardous area, ATEX zone 1. It's available as a 3- or 6-channel version.
The ExTrend 200i has a backlighted TFT-LC-display with an active area of 115,2 mm x 86,4 mm and a resolution of 320 x 240 pixel.
The ExTrend 200i is intrinsically safe and it requires a power supply and interface module IPM 300i, which has to be installed in the safe area.
