Basic circuit diagram DRC MCM XT<br />
DRC MCM XT Status Display software<br />
DIN rail mounted device with integrated LifeCheck sensor for condition monitoring of max. ten<br />
LifeCheck-equipped BLITZDUCTOR XT/XTU arresters. A three-coloured LED and a remote signalling<br />
contact (break or make contact) indicate the operating state of the arrester.<br />
The free "Status Display and Service Console" software can be optionally used via an RS485 interface<br />
converter. The software allows to remotely monitor the condition of all monitored arresters by<br />
means of a PC.<br />

USB Interface Converter of Type USB NANO 485<br />
USB NANO 485 converts between USB and RS-485 signals. The<br />
interface converter is specifically designed for two-wire RS-485<br />
buses. LEDs indicate operation (yellow), Rx (green) and Tx (red).<br />
USB NANO 485 is ideally suited for use with notebooks due to<br />
its compact dimensions. Stationary use is also possible.<br />
