Backplane Bus Architecture and I/O Density Scaling

  • The GE 369-HI-R-M-0-2-0-0 plugs into the internal expansion slot of the Multilin 369 base unit, communicating across a dedicated internal expansion bus to increase system channel density without additional power supplies.
  • Deterministic backplane messaging delivers low latency between field digital inputs and internal protection firmware algorithms, enabling high-speed trip signal execution.
  • The module features 2500 VAC galvanic isolation between field terminal points, logic circuits, and chassis ground to protect sensitive core processing circuitry from high-voltage field transients.
  • Firmware flash compatibility ensures seamless parameter mapping when expanding digital monitoring channels for auxiliary contacts, trip interlocks, and 4-20 mA transducer retransmission loops.

Frequently Asked Questions

Q: What is the maximum contact switching capacity for the digital relay outputs on the 369-HI-R-M-0-2-0-0?

A: The four Form C electromechanical output relays are rated for 8 A at 250 VAC or 30 VDC resistive loads, making them suitable for direct contactor switching.

Q: How does the module handle signal conditioning for different field digital input voltages?

A: The digital input channels incorporate internal high-impedance (3.3 kΩ typical) wet/dry contact sensing circuits that accept wide-range inputs from 24 to 240 VAC or 24 to 125 VDC without external drop resistors.

Q: Can the 369-HI-R-M-0-2-0-0 expansion card be hot-swapped while the Multilin 369 base unit is powered?

A: No, the control power to the main 369 relay chassis must be completely isolated and de-energized prior to inserting or removing the expansion card to prevent edge-connector damage.

Field Installation Guidelines

  1. De-energize and lock out all AC/DC auxiliary control power connected to the Multilin 369 motor protection unit before removing panel covers.
  2. Wear a grounded ESD wrist strap connected to panel earth to prevent electrostatic discharge during module insertion.
  3. Align the card edge guides with the internal chassis slot on the 369 base unit and press firmly until the 20-pin expansion connector seats fully.
  4. Tighten top and bottom module faceplate screws to establish solid chassis ground continuity and secure the assembly against vibration.
  5. Wire field I/O connections to the removable terminal blocks using 14-22 AWG copper conductors, ensuring signal shields are grounded at one end only.
