The GE Multilin 469-P5-HI-A20-T is part of the 469 Motor Management Relay family produced by GE Digital Energy. It is a 5A Phase secondary 90-300VDC 70-265VAC with an enhanced display. Additionally, it incorporates an ethernet port on the back of the relay. The "T in the part number 469-P5-HI-A20-T indicates the addition of the optional ethernet enhancement. A SR469 case with a cut-out in the back must be used to allow access to the port. While no harsh environment conformal coating is present with this model, adding a "H" to the part number in the order code would indicate conformal coating.  Information regarding how to configure a relay with ethernet communication can be found in the "Configuring Ethernet Communications" section of the GE Multilin 469 Manual part number 1601-0122-A9. The EnerVista 469 setup software must be used to configure the 469-P5-HI-A20-T properly. The EnerVista 469 software may come preloaded on a CD with the relay purchase, or it can be easily downloaded from General Electric's online resources. EnerVista 469 can be used to configure setpoints and export system data for later analysis.

summarize The MIF II is a member of the MII family of protective relays that function as primary loop protection in distribution networks of any voltage level, as well as backup/auxiliary protection for transformers, generators and motors. Protection features include time-delay overcurrent, instantaneous overcurrent (two stages) and thermal image protection. Depending on the model selected, the overcurrent element can be either three-phase and grounded, or single-phase. Optional protection features include cold load start, circuit breaker failure protection, circuit breaker condition, configurable logic, and automatic reclosing. Each protection element can be selectively enabled or deactivated through the front panel or communication. Flexible setup and optional ANSI, IEC, IAC or EPTAR-C curve models ensure proper fit with other devices. The standard configuration of the MIF II relay has 2 fixed digital inputs and 6 fixed digital outputs. As an alternative, 2 inputs and 4 outputs can be configured by the user. The standard MIF II has 6 fixed status LED indicators, or 4 of them can be configured by the user. The panel also has a 5-key keypad and a 16x2 LCD display, which are easy to use user interfaces. The user can use the keyboard on the panel to set the communication baud rate and relay address. The relay is configured with a front RS232 communication port and a rear RS485 communication port to which the computer connects and accesses the relay via the ModBus®RTU protocol. By using an external converter, such as GE Multilin DAC300 or F485, the rear RS485 port can be converted to an RS232 port or a fiber optic port (plastic or glass fiber). Windows® based EnerVista software for setting up and configuring MIF relays is included free of charge. The MIF II relay is accessed from a computer using the MII EnerVista Setup software through the RS232 communication port located on the relay panel. Use EnerVista software to view or modify relay setting values and configure relays (input, output, LEDS and configurable logic), as well as display measurement information and real-time status of relays. If the relay is equipped with the appropriate options, EnerVista software can be used to display the latest fault information, such as incident reports and wave logging. The MIF has a drawout structure and is housed in a 1/4 19 "chassis.
