EPRO MMS 6120 Dual Channel Bearing Vibration Monitor

EPRO MMS6120 is a dual-channel bearing vibration measurement module. It monitors the vibration conditions of bearings in a wide range of rotating equipment, thereby ensuring smooth operation and prolonging the equipment's lifespan.

Module and sensor supervision:

Channel clear/circuit fauit sensingsystem; the internal modul supervisioncircuitry continuously supervises thefollowing functions:Sensor signal is within a preset window.Cabling between sensor and modul is ok(no shortcircuit, no break).System supply voltages are within presetwindows.Configuration and parameter settingsare correct.Measuring range not overloaded.

Internal temperature not overloaded.System watch dog.During changing from a sensor malfunc-tion into the ok status or after switchingon the modul a delay time of 15 sec. isoperable."Channel clear" is visualised on the frontof the module by means of a green LED;this LED switches off during a "channelfault"; during the delay time the LEDflashes.The channel status is also indicated via a binary output, separately for each of thetwo channels.Umax- 48 V dc= 100 mAmaxThe reasons for a "channel fault" indi-cation can be read out via the communi-cation buses; which enables service per-sonel to take immediate corrective mea-sures.

Signal outputs at the connecting strip:

Terminal strip on rear side:acc. to DIN 41 612 , version F 48 MRS 485 communication interface.
Two independent current outputs:

One for each channel; outputs are pro-portional to the selected operatingmode.
0/4..20 mA;configurable,open- andshortcircuit proofPermissible load: < 500 OhmsAccuracy: 16 bit resolution; ±1 % of fullrange

Settling time: 0 .. 10 sec.; configurablein increments of 1 sec. separately foreach channel.

Two independent voltage outputs:

One for each channel; outputs are pro-portional to the selected operating mode(e. g. shaft vibration amplitude S1..)0 ... +10 Volt, open and shortcircuit proofLoad resistance: > 10 kOhmResolution: 8 bit
