Model Definition

• 0-54392-2: Base part number (PC Control/Interface Board)

• Alternative IDs: 0543922, O-54392-2

• Status: Discontinued by manufacturer; no direct OEM replacement

• Cross-Reference: No fully compatible equivalent; requires exact part match

Technical Specifications

• Form Factor: Standard 3U PCB (approx. 248 × 171 mm)

• Weight: ~0.55 kg (1.2 lb)

• Logic Voltage: ±15 VDC, +5 VDC, +24 VDC (from system power supply)

• Signal Types: Analog (0–10 VDC), digital (24 VDC logic), relay contact signals

• Components: Op-amps, digital logic ICs, opto-couplers, terminal blocks, status LEDs

• Protection: Overvoltage, ESD, and transient surge protection

• Operating Temp: 0 °C to +55 °C

• Mounting: 3U rack slot, goldfinger edge connector (AutoMax/MaxPak backplane)

Interfaces & Communication

• Backplane: 3U edge connector (interfaced with drive CPU and power supply)

• Field Wiring: Screw terminals for analog/digital I/O and control signals

• Internal Links: Flat-cable connectors for inter-board communication

• No Network Ports: Hardwired interface board; no serial/Ethernet communication

Key Features

1. Signal Conditioning: Converts and buffers analog/digital signals for drive control

2. Isolation Protection: Opto-couplers separate low-voltage logic from high-power circuits

3. Status Monitoring: On-board LEDs for power, signal, and fault diagnostics

4. Compact 3U Design: Fits standard AutoMax/MaxPak rack enclosures

5. Pre-Wired Terminals: Labeled screw terminals simplify field installation

Application

• Drive Systems: AutoMax DC Drives, MaxPak Series DC Drives (50–2000 HP)

• Subassemblies: Control racks, logic cabinets, I/O interface panels

• Industries: Steel, paper, mining, cranes, conveyors, machine tools

• Function: Central signal interfacing and control logic for DC drive systems

Compatibility

• Compatible Racks: AutoMax DCS Rack, MaxPak Drive Rack

• Voltage Compatibility: 230/460/575 VAC DC drives

• Power Range: 50–2000 HP (matches AutoMax/MaxPak drive ratings)

Critical Notes

• Function Distinction: Different from 0-54390 (power supply); this is a control/interface board

• Replacement Challenge: No direct substitute; refurbished units are standard solution

• Availability: Limited stock; longer lead times; pricing varies by condition
