The MM200 includes high accuracy metering of current signals. Current parameters are available as total RMS magnitude.

Digital Counters
The MM200 provides ten digital counters to aid in system analysis. The digital counters can be used for scheduling inspections on equipment, performing qualitative analysis of system problems and spotting trends.

Learned Data
Monitoring the motor’s operating characteristics assists in determining the motor start parameters and is a critical tool for determining the operating characteristics of the system, motor and connected load.

Advanced Device Health Diagnostics
The MM200 performs comprehensive device health diagnostic tests during startup and continuously at runtime to test its own major functions and critical hardware. These diagnostic tests monitor for conditions that could impact the MM200’s performance, evaluate the criticality of this impact and present device status via SCADA communications. Providing continuous monitoring and early detection of possible issues helps improve system availability by employing predictive maintenance

The Hand Held Display (HHD) provides a rugged local interface for MM200 Motor Protection Systems where a local display is not used in the MCC.
The HHD provides a graphical color local interface to the MM200 Motor Protection Systems allowing local operators to view and change setting files and quickly access relay diagnostic information.
The HHD provides a clear and detailed view of all motor settings, diagnostic information and metering data available in the MM200 allowing local operators to make informed decisions on the motors operation.



	Networking through RS485 Multiple protocols - Modbus RTU - ODVA Compliant DeviceNet - Profibus DPV1 Simultaneous Communications

The MM200 utilizes the most advanced communications technologies available today making it an easier and more flexible motor protection relay to use and integrate into new and existing infrastructures. Multiple communication ports and protocols allow control and easy access to information from the MM200. All communication ports are capable of communication simultaneously.

The MM200 supports the most popular industry standard protocols enabling easy, direct integration into HMI and electrical SCADA systems. Modbus RTU is provided standard with a RS485 networking port. The following optional protocols and communication ports are available:

Fieldbus Protocol with dedicated port.
- ODVA Compliant DeviceNet
- Internally powered Profibus

Access Control
Multilin devices and relays are designed with simple but powerful security to enable reliability and compliance for virtually any project or implementation. With support for multi-level permissions and multi-factor supervisory controls, Multilin devices can help you manage the integrity of your system during commissioning, testing, implementation, and beyond. The MM200 provides separate authentication for settings and commands to the system. In addition, as discrete authentications for local and remote access, it also provides a supervisory control factor that can lock or unlock a device for configuration changes and other modifications.

Intrusion Detection
Multilin’s family of protection and control products can also help enable your security perimeter and intrusion detection programs. By providing essential alarming and logging of critical events, Multilin devices can help you detect potential breaches within your system and allow you to respond quickly and effectively. Specifically, unsuccessful access attempts are logged, alarmed, and lead to potential attackers being locked out. This ensures the reliability of your system during questionable activity.control factor that can lock or unlock a device for configuration changes and other modifications.


Auditing and Reporting With the Security Audit Trail reporting feature and support for Event logging of key activities such as configuration changes, Multilin devices can help ensure device and protection system integrity, and perform forensic auditing of activities and changes for compliance.
