0-57407: Basic model (AutoMax system CPU card)

4: 4th generation hardware, ultimate top-of-the-line version

Often with suffix H: High-Reliability (high reliability / shockproof enhancement)

Full name: Processor Module for AutoMax / DCS 5000

Compatibility: Direct replacement for 0-57407-1/2/3/3E; used in conjunction with 0-57406 drive control card.

Technical Specifications (Official)

Manufacturer: Reliance Electric (now Rockwell Automation)

Processor: Intel 80286 16/32-bit CPU, hardware watchdog

Program memory: 1MB EPROM / 512KB RAM

Data memory: 512KB battery-backed RAM (twice the size of 3E)

System bus: AutoMax backplane high-speed bus

Communication interfaces:

PROGRAMMER: 25-pin parallel port (programming / downloading)

LOCAL COMM: 25-pin parallel port (upper computer / HMI)

Operating temperature: 0°C ~ +60°C (wide temperature range, H version enhanced heat dissipation + shockproof)

Isolation: 2500 VAC photoelectric isolation

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

Power consumption: ≤ 24 W

Protection: IP20, PCB three-proof coating (damp-proof / dust-proof / corrosion-proof)

Front panel interfaces and indicators

Dual-digit display: Fault code display (00 = normal)

OK (green): CPU running normally

FAULT (red): Hardware / program / communication failure

2×25-pin parallel port: Up = PROGRAMMER, Down = LOCAL COMM

Top and bottom snap: Support hot swapping Core function

System main CPU: AutoMax/DCS 5000 core, capable of executing ladder diagrams, BASIC, and control block programs.

Enhanced data processing: Memory doubled, supports 16-axis motion control + complex closed-loop + redundancy.

4/H version enhancement: 100% aging screening of components, three-proof coating, wide temperature range, preferred for long-term operation in harsh conditions.

Redundancy and hot-swappable: Dual CPU redundancy, on-site replacement of the rack, no production interruption.

Version comparison (0-57407 series)

0-57407-1: 0-50°C, first generation, basic functions

0-57407-2: 0-55°C, enhanced heat dissipation

0-57407-3E: 0-60°C, wide temperature range + EMC strengthening, mainstream stable version

0-57407-4/4H: 0-60°C, doubled memory + three-proof + high reliability, top-of-the-line for the entire series

Typical applications

System: Reliance AutoMax / DCS 5000

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

Purpose: Automation of the entire production line, multi-motor synchronization, drive cluster control, high-speed and high-precision motion control, high-reliability redundant system.

Installation and maintenance Installation

Disconnect the power supply, insert the machine frame CPU slot, lock the latch; connect the programming/communication cables.

When powered on, the OK light is on and the digital display shows 00, indicating normal operation. The system automatically recognizes the I/O and driver cards. Maintenance

Quarterly: Check the status of the LED, communication connector, and snap fastening.

Half-yearly: Power off and perform anti-static cleaning of the panel and slots (three-layer coating does not require frequent cleaning).

Replacement: 4/4H can directly replace 1/2/3/3E without changing the program / wiring; reverse replacement requires downgrading the memory and functions.
