GE Multilin 469-P5-HI-A20-T motor management relay

About the 469-P5-HI-A20-T-H

• The 469-P5-HI-A20-T-H is a model from GE Multilin’s 469 series, designed for integrated management and protection of large and medium motors.
• The “H” in the product description indicates an optional conformal coating, providing enhanced durability.

Control Power and Connectivity

• It is a high control power unit, denoted by “HI” in the model number.
• It accepts control power inputs in the range of 90 to 300 VDC or 70 to 265 VAC at 48 to 62 Hz. This differs from low-power counterparts that use 24 to 60 VDC or 20 to 48 VAC at 48 to 62 Hz.
• This model includes the optional Ethernet 10BaseT, RJ45 connection.
• The Ethernet port utilizes ModBus RTU over TCP/IP protocol.

Caution: When removing the relay from its case, ensure the rear RJ45 connector is cleanly disconnected to prevent damage. If the network cable is long enough (over 16 inches), the unit can be removed without disconnecting the cable.

Protective Features

• Features a variety of protective elements, including:
  • Torque protection
  • Mechanical jam protection
  • Undervoltage & overvoltage protection
  • Current unbalance correction

These protective features are highly configurable, allowing system trips to activate based on user-specified quantities and time intervals.These features help prolong motor life and reduce downtime by shielding components during potentially harmful system events.
