409-S RPM Monitor

Listing ID #3195528

409-s rpm indicator is for measuring the rotating speed of a turbine or other rotating machines; it accepts input signal from proximity sensortransducer based on eddy current principle, it can also accept input signal from other type of proximity sensors, photoelectric sensors, limit switches and rotary encoders, the unit has a isolated built-in 24v dc excitation supply to power the input sensors.
409-s rpm indicator comes with 2 set points and relay outputs for alarm and trip purpose, the set points and relay logic can be user set for over speedunder speed alarming and protection, the unit has built-in acknowledge logic for maintained as well as momentary alarms, the relays can be configured for normal or fail-safe operation. Isolated analog output by way of currentvoltage is available for interface with plcdcs systems, also isolated rs485 modbus rtu port is provided to incorporate the 409-s in a plant wide scadasystem.
409-s rpm indicator is compact, reliable and fit for most critical speed monitoring and protection, the unit can be programmed for number of eventsrotation and displays the speed from 1 rpm to 10000 rpm on a bright 5 digit display the brightness of which is adjustable to suit any environment.
