Measurement Range:Input signal frequency 0-20kHz,maximum speed 65535rpm.
Output Signal:Each MMS6350 module has two 0/4-20mA current outputs,proportional to the speed,with an accuracy of 0.1%;one TTL output with open-circuit and short-circuit protection;and six individually configurable binary outputs.
Features:
Three-Channel Design:Employs a 3-out-of-2 speed measurement system.Each MMS6350 module acquires a signal from a pulse sensor.The microprocessor compares the pulse input and output signals from all channels and uses a 3-out-of-2 logic for alarm output,improving system reliability and safety.
Multiple Measurement Modes:Can measure pulse signals triggered by the gear disc and calculate the speed based on the time interval between two signals.Two measurement modes are available:n measurements per revolution and one measurement per revolution.
Self-Test Function:Built-in self-test function for sensors and module channels allows for system self-checking during operation,ensuring normal system operation.
Extensive Communication Interfaces:Equipped with RS232/RS485 ports for field configuration and communication,and an optional Profibus-DP interface for easy data exchange and network connectivity with other devices.
Password Protection:Each monitor is password protected,enhancing system security.
Peak Memory:Integrated peak memory function allows the system to read the maximum RPM value before machine shutdown,providing crucial information for assessing the impact of overspeed on mechanical load.
