ETR-2002 Return Transmission Modul

l             This moulding board adopts world famous optical receiving device such as Mitsubishi or E-O and Ortel, insure capability tranquilization
l       The insider controlling circuit guarantee laser's long and steady work
l        The laser is the most precious part of the whole device, so the insider controlling circuit is installed. Once the laser’s working specification is off the permitted range, circuitry will automatically turn off the power of the laser and the red alarm lamp will be lighted.
