1. Model Definition

• 0-57413: Base 64K common memory module for AutoMax multi-processor racks

• -B: Revision B, early production, no conformal coating, standard temperature range

2. Basic Specifications

• Memory Size: 64K words (16-bit), shared across all rack processors

• Function: Global data exchange, inter-processor communication, system-wide shared variables

• Power Supply: 5 V DC ±5% from backplane; 1.2 A typical

• Operating Temperature: 0 °C to +55 °C

• Storage Temperature: −40 °C to +85 °C

• Dimensions (W×H×D): 32 × 298 × 187 mm

• Weight: ~0.84 kg (1.86 lbs)

• Conformal Coating: None (Rev B; later Rev C/D/E added coating)

• Manual: J-3636 (Common Memory Module User Guide)

3. Interfaces & Communication

• Backplane: AutoMax DCS 5000 system bus, slot 0 dedicated

• Status LEDs: Power, Ready, Fault, Access

• Edge Connector: 96-pin DIN 41612, backplane interface

• Front Panel: No user I/O; LED indicators only

4. Key Functions

• Enables multi-processor coordination in AutoMax racks (2–8 processors)

• Provides 64K shared memory for global tags, I/O data, and inter-task messaging

• Supports synchronous/asynchronous data access between all system CPUs

• Fault monitoring: parity error, time-out, bus fault, power fail

• Rev B specifics: original circuit layout, no environmental coating, lower noise immunity than later revisions

5. Applications

• AutoMax DCS 5000 multi-processor systems (rolling mills, paper machines, metal processing)

• High-speed line shafts, coordinated drive systems, and complex motion control

• Legacy Reliance Electric DC drive/PLC retrofits

• Direct replacement for 0-57413-1 / -2 in older racks
