Intrinsically Safe Modem
Description
Technical spec
Within development and further operation of automation systems for mining equipment it becomes necessary to transmit data for long distances (about 7-10 km) from data sender to data receiver through available communication lines (telephone copper pair).
For this purpose, we offer data modem BOSmodem. BOSmodem ensures data transmission from different automated process control systems (ASUTP) to dispatcher’s workstation (ARM).
