Q2: What does the “PD” in MMII-PD-1-2-120 mean?
A: PD indicates the panel-mount version with a local display. The front panel provides an LCD, keypad and status indicators for local operation and monitoring.
Q3: What does the “1-2” configuration mean?
A: The 1 represents the process-control option, including process inputs, undervoltage autorestart and diagnostics. The 2 represents the enhanced protection option, including additional motor protection and control functions.
Q4: What power supply does MMII-PD-1-2-120 use?
A: The model is configured for 120 VAC control power. The “120” at the end of the part number identifies this control-voltage configuration.
Q5: What protection functions does the MMII-PD-1-2-120 provide?
A: It can provide protection against conditions such as thermal overload, phase loss, phase imbalance, ground fault, stalled/locked rotor, overvoltage and undervoltage. The exact functions available depend on the installed option configuration.
Q6: Does MMII-PD-1-2-120 support communication with a control system?
A: Yes. The MMII platform supports RS-485 communication and Modbus RTU, with commonly specified baud rates from 1,200 to 19,200 bps. This allows connection to supervisory control systems such as SCADA or DCS.
Q7: What are the dimensions and weight of MMII-PD-1-2-120?
A: The approximate dimensions are 188 × 112 × 127 mm, and the unit weighs approximately 1.36 kg (3 lb).
Q8: What is the MMII-PD-1-2-120 commonly used for?
A: It is used for motor protection, control, monitoring and diagnostics in applications such as pumps, compressors, fans and motor control centers. Its integrated functions can reduce the need for separate motor-protection and monitoring devices.
