mining belt conveyor protection device

mining belt conveyor protection device I. function features the device has such functions as dual-motor drag the start and stop time control, deviation failure and emergency stop digital display, and centralized control display. during the nomal operation, it can realize the real-time display of such parameters as belt speed, belt tension, roller temperature, electric current etc. when the fault occurs, it can show the failure features and give warning voice. the device has a voice pre-warning and a voice incident alarm, which can not only display the failure nature, but also report the failure belt drive. the sensor adopts fast-plug connection, which is time-saving, efficent and convenient. II. the hardware parameters 1. the core control is an advanced micro-processing chip. 2. 16-channel analog input interface, 8-channel PT100 input interface 3. 1-channel input frequency interface 4. 8-channel switch input interface 5. 5-channel switch output interface 6. large screen LCD dislay(128x64) 7. with RS-485 communications interface 8. with such protection function as the fault longitudinal of the a deviation, cable and tear, the ral-time speed of the tape, temperature, electrical current etc. III. technical parameters A. the rated input voltage: AC 127V B. allowed voltage fluctuation: -25% 10%Ue C. the max. output open circuit voltage: 12V±0.5V D. the max. output short-circuit current: DC40mA E. overcurrent protecting setting: 1500mA F. the relay output contact capacity: AC250V/5A
