Model Explanation 0-57406-H

0-57406: Basic model (AutoMax drive control core board)

H: Final hardware revision (full functionality + highest stability + enhanced EMC)

Full name: Drive Controller Module

Compatibility: AutoMax PLC / DCS 5000 rack; can be directly replaced with C/D/E/F versions, reverse compatibility requires program confirmation.

Technical parameters (official)

Manufacturer: Reliance Electric (now Rockwell Automation)

Processor: Intel 80186 16-bit CPU, hardware watchdog

Number of control axes: Up to 8 axes (combined with I/O module expansion)

Memory: 128KB RAM / 256KB EPROM

Communication: RS-232 (DB9, programming / debugging), AutoMax backplane bus

Operating temperature: 0°C ~ +60°C (same as E/F, but more resistant to interference and stability)

Isolation: 2500 VAC photoelectric isolation between backplane and control circuit

Size: 342 × 190 × 30 mm (standard 1.25" slot)

Weight: Approximately 0.9 kg

Power consumption: ≤18 W

Protection: IP20

Interfaces and indicators

Backplane: Special edge connectors (power, address, high-speed data)

Front panel:

2-digit digital display: Display fault codes (00 = normal)

OK (green): Module is running normally

FAULT (red): CPU / program / communication failure

TEST switch: 3 positions (self-check / operation / debugging)

RESET button: Hardware reset

RS-232 port: DB9, connects programmer / upper computer Core function

Drive main control core: The central control unit of the AutoMax system, managing GV3000 and other frequency converters.

Multi-axis synchronous control: Single card 8-axis speed/position closed-loop control, supporting multi-motor synchronization and tension control.

Independent program execution: Equipped with its own CPU and memory, capable of independently executing control logic without relying on the host computer.

Top-level anti-interference and stability: Version H is the final production version, with enhanced EMC, optimized cooling, and component upgrades, suitable for long-term continuous operation.

Hot-swappable: The rack can be replaced while powered on, without interrupting system operation.

Version differences (C/D/E/F/H)

0-57406-C: 0-50°C, basic anti-interference, first generation

0-57406-D: 0-55°C, enhanced cooling/anti-interference, replacement for C

0-57406-E: 0-60°C, wide temperature + enhanced EMC, mainstream replacement

0-57406-F: 0-60°C, similar functions to H, small batch

0-57406-H: 0-60°C, full functions + highest stability + final version

Typical applications

System: Reliance AutoMax / DCS 5000

Industry: Metallurgy, papermaking, water treatment, power, heavy machinery

Purpose: Multi-motor synchronization, frequency converter cluster control, high-speed production line, tension control (preferred H version for high reliability / long-term operation scenarios)

Installation and maintenance Installation

Disconnect the power supply, insert the rack slot, lock the panel; connect the RS-232 programming cable.

Power on: The OK light is on, the digital tube shows 00, which indicates normal operation. The CPU automatically recognizes.

Maintenance

Quarterly: Check the terminal connection, the status of the LED / digital tube, and the communication cables.

Half-yearly: Disconnect the power supply, perform anti-static cleaning of the panel and slots.

Replacement: H can directly replace C/D/E/F; no need to modify the program / wiring; reverse replacement requires testing compatibility.
