PROFIBUS-DP and Axial Position Signal Processing
The MMS6250 processes electrical measurement signals for digital axial position protection. The specified input voltage range is 0…27.3 VDC, while the stated limit range extends to 0…30 VDC.
The input resistance exceeds 100 kOhm. Therefore, the input presents a high-resistance measurement interface to the connected signal circuit. The specified voltage measurement range is 0…4.1 V, with an accuracy of +/-1% of full scale.
The module supports signal frequencies from 0 to 10 Hz. Its internal resistance is specified as 10 kOhm. In addition, the PROFIBUS-DP interface provides digital communication between the protection module and the connected monitoring or control system.

Field Installation Guidelines
Install the MMS6250 according to the equipment arrangement and wiring documentation of the associated monitoring system. Verify the module identification before connecting field wiring.
Route signal wiring separately from high-current power conductors and switching circuits where practical. Maintain proper shielding and grounding practices for low-level measurement signals. Connect the PROFIBUS-DP communication wiring according to the network topology and termination requirements of the installed system.
Before energization, verify the input voltage against the specified 0…27.3 VDC operating range. Also check the connected signal circuit for correct polarity, cable continuity, and termination.
Do not use the estimated shipping dimensions as a confirmed mounting envelope. Confirm the actual module dimensions and mounting arrangement from the applicable Epro installation documentation before mechanical installation.
