Model Explanation 0-57406-K

0-57406: Basic Model (AutoMax Drive Control Core)

K: Final Industrial Enhanced Version (with component aging screening + conformal coating for protection against moisture, dust, and corrosion, designed for extreme working conditions)

Full Name: Drive Controller Module

Compatibility: AutoMax PLC / DCS 5000 Rack; Can be directly replaced with C/D/E/F/H versions. Reverse compatibility requires program confirmation.

Technical Specifications (Official)

Manufacturer: Reliance Electric (now Rockwell Automation)

Processor: Intel 80186 16-bit CPU, hardware watchdog

Number of Control Axes: Up to 8 axes (compatible with I/O expansion)

Memory: 128KB RAM / 256KB EPROM

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

Operating Temperature: 0°C ~ +60°C (same as H version, but higher stability for long-term high-temperature operation)

Isolation: 2500 VAC Photoelectric Isolation (backplane ↔ control circuit)

Size: 343 × 203 × 38 mm (standard 1.25" slot)

Weight: Approximately 0.9 kg

Power Consumption: ≤18 W

Protection: IP20 (PCB conformal coating, moisture-proof / dust-proof / corrosion-proof)

Interfaces and Indicators

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

Front Panel:

2-digit digital display: Fault code display (00 = normal)

OK (green): Normal operation

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: AutoMax system central control unit, managing GV3000 and other frequency converters.

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

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

Enhanced for extreme conditions: Version K offers the highest stability for the entire series, with 100% aging screening of components + three-layer anti-corrosion coating, suitable for high-temperature, humid, dusty, and strong-vibration environments.

Hot-swappable: Replaceable during power-on of the frame, without interrupting system operation.

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

0-57406-C: 0-50°C, basic immunity, first generation

0-57406-D: 0-55°C, enhanced heat dissipation/immunity, replacement for C

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

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

0-57406-H: 0-60°C, full functionality + high stability, final production version

0-57406-K: 0-60°C, component screening + three-layer anti-corrosion coating, dedicated for extreme conditions, top configuration for the entire series

Typical applications

System: Reliance AutoMax / DCS 5000

Industry: Metallurgy (high temperature / dust), papermaking (humid), water treatment, power, heavy machinery (strong vibration)

Purpose: Multi-motor synchronization, frequency converter cluster control, high-speed production line, tension control (preferred version K for extreme conditions / long-term continuous operation)

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 display shows 00, which indicates normal operation. The CPU automatically recognizes.

Maintenance

Quarterly: Check the terminals, LED / digital display, communication cables.

Half-yearly: Disconnect the power supply, perform anti-static cleaning of the panel and slot (three-layer coating does not require frequent cleaning).

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