EPRO MMS3311/022-000, NC: 9100-03079-00 Dual channel speed/key phase transmitter

The EPRO MMS3311/022-000 is a dual-channel speed/key phase transmitter with the following details:

Brand and Model:
Brand: EPRO
Model: MMS3311/022-000
Main functions:
The transmitter is used to measure and process the speed and key signal, mainly used to monitor the speed of the shaft, and give the key phase pulse.
The key signal can be triggered by the key phase slot on the shaft, or it can be generated by the velocity measurement gear disk.
Technical features:
Input: The measurement input is eddy current sensor with built-in preprocessor. The input of the transmitter is the epro eddy current sensor PR6422/… , PR6423/… , PR6424/… , PR6425/… , and PR6426/… .
Output:
All the way proportional to 1/4 of the speed… 20mA current output.
One key phase output.
Two buffered voltage outputs (2-10V), one way per channel, proportional to the input signal, are used for testing and can also be used for analytical and diagnostic purposes.
One “OK” status output and two limit outputs.
Power supply: 18… 24… 31.2V DC; The transmitter circuit is electrically isolated from the power supply via a DC/DC converter.
Environmental conditions: in line with IEC359, DIN43745 standards, shell corrosion resistance, aluminum; Protection level IP65.
Built-in function: Built-in “self-check” circuit to monitor sensor and transmitter circuit faults, once the fault is found, the logic “OK” output will change state, while the current output changes from 4-20mA to 0mA.
