Model Definition

• 0-54363: Base part number (Control Input Board / Frequency Input Card)

• Status: Discontinued by manufacturer; no direct OEM replacement

• Cross-Reference: No fully compatible equivalent; replacement requires exact part match or system reconfiguration

Technical Specifications

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

• Weight: ~0.6 kg

• Input Signals: 24 VDC digital control inputs; frequency feedback (0–10 kHz)

• Logic Voltage: 5 VDC internal; 24 VDC external I/O

• Components: Digital logic ICs, opto-isolators, signal conditioning circuits, LED indicators

• Operating Temp: 0 °C to +55 °C

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

Interfaces & Communication

• Backplane: 3U goldfinger edge connector (fits AutoMax/MaxPak rack)

• External I/O: Screw terminals for 24 VDC control inputs and frequency encoder feedback

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

Key Features

1. Digital Control Inputs: Isolated 24 VDC inputs for start/stop, direction, and enable commands

2. Frequency Feedback Processing: Converts encoder frequency signals to digital data for speed regulation

3. Opto-Isolation: Electrical isolation between external circuits and drive logic to reduce noise

4. LED Status Indicators: On-board LEDs for power, input status, and fault diagnostics

5. Compact 3U Design: Seamless integration into existing AutoMax/MaxPak drive cabinets

Application

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

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

• Function: Primary interface for external control signals and speed feedback in 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: Separate from 0-54339 (memory board), 0-54341 (rectifier suppressor), and 0-54346 (static rheostat board)

• Replacement Challenge: No direct substitute; refurbished units are the most common solution

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