Micro Processor Based Data Logger

Microprocessor based data logger essentially logs various railway signal control and interlocking relays to verify, diagnose its operation & maintenance. Data logger logs the change of status of every relay connected to it. Logged data transmitted upon to the central place to generate various exceptions, reports and other information by application software.
Features:
Maximum 4096 opto isolated digital inputs @ 16 msec sampling and 96 individually isolated analog input voltage channels @ 1 sec. Non-volatile data storage (more than 26 lacks) in nand flash and can be retrieved into memory card. LCD, LED and key board interface for user interaction. Printer interface for hard copy of logged data, 8 serial communication ports with high data rates, Inbuilt dual modem for network, Potential free relay contacts to control from central place, Audio – visual alarms on exceptions and faults
Benefits:
Status-orientated maintenance means less maintenance effort and hence savings in human and material resources. Early recognition and clearing of faults reduce the number of delays considerably, A long-term evaluation of past measurement data is possible. This data can be useful in other applications like train charting, train management system, wrong operation information system, integrated passenger information system etc..
