Product Details：

Product Dimensions：

Reliance Electric processor modules, primarily from their AutoMax series, were the central processing units for their Programmable Logic Controllers (PLCs) and Distributed Control Systems (DCS). These modules were designed to execute control logic, manage communication, and oversee the operation of various I/O modules and other system components in industrial applications.

Product Details

Functionality:

RELIANCE processor modules are the "brains" of the AutoMax control system. They execute user-programmed application programs, which typically involve ladder logic, function block diagrams, or BASIC programming.
They manage data exchange with I/O modules, communication modules, and other processors in a multi-processor configuration.
They handle system diagnostics, fault detection, and error reporting.

Architecture:

These modules typically plug into a backplane within an AutoMax rack, communicating with other modules (I/O, power supply, communication) via the backplane.
Some systems supported multiple processor modules within a single rack to enhance processing capability and memory.

Key Features (Typical for AutoMax Series):

Microprocessor-based design (e.g., Motorola 68010, 68020, 68030).
Support for multiple programming languages (Ladder Logic, Control Block, BASIC).
Serial communication ports (RS-232C) for programming and communication.
LED status indicators for diagnostics (e.g., "BAT OK," "OK," fault codes).
Battery-backed RAM for program retention during power loss.
Robust design for industrial environments.

Product Parameters (Examples for AutoMax 6010/6011/7010 Processors)

Microprocessor: Motorola 68010 (16-bit), 68020 (32-bit), 68030.
CPU Speed: Typically in the range of 8 MHz to 25 MHz.
Memory:

RAM for application programs (e.g., 135K-150K for 6010, up to 512K for 7010).
Lithium battery-backed RAM for program retention.

Communication Ports:

Two independently-isolated 25-pin "D" shell RS-232C connectors per module. One typically reserved for programmer connection.

Diagnostics:

LED indicators for battery status (BAT OK), operational status (OK), and 7-segment displays for fault codes.

Rack Compatibility: Designed to fit into specific AutoMax 10-slot or 16-slot racks.
Power Consumption: Depends on the specific module, supplied via the backplane from the system power supply.
Programming Software: Required specific DOS-based or early Windows-based software (e.g., AutoMax Programming Executive v. 2.1J or later, v. 3, v. 4).

Product Advantages (Historical Context)

Reliability: Reliance Electric products were known for their ruggedness and reliability in industrial applications, crucial for minimizing downtime.
Flexible Programming: Support for multiple programming languages allowed engineers to choose the most suitable method for their control tasks.
Distributed Control Capabilities: The AutoMax system allowed for distributed processing across multiple processor modules within a rack or across a network (e.g., DCSNet), enabling complex and large-scale control systems.
Scalability: The modular nature of the AutoMax system allowed for expansion of I/O and processing power as application requirements grew.
Diagnostic Features: On-board LEDs and fault codes aided in quick troubleshooting.

Important Considerations (Especially for Legacy Systems)

Obsolete Status: RELIANCE Electric processor modules are largely considered obsolete by the original manufacturer (now Rockwell Automation).
Limited Support: While some third-party companies offer repair services and sell refurbished modules, direct manufacturer support is minimal or non-existent.
Software Compatibility: Finding compatible operating systems and programming software (often DOS-based) can be challenging. Old computers or virtual machines might be required.
Spares Availability: Sourcing spare parts (modules, batteries) can be difficult and expensive due to limited availability.
Migration Planning: For critical applications, planning for migration to modern control platforms (e.g., Rockwell Automation's current Allen-Bradley PLC lines) is highly recommended due to the risks associated with aging hardware.
Documentation: Accessing original manuals and technical documentation might require specialized resources or community forums.

Product Applications (Historical and Current Niche Use)

Heavy Industry: Steel mills, paper mills, automotive manufacturing.
Process Control: Chemical plants, power generation facilities (though many have been upgraded).
Discrete Manufacturing: Machine control, assembly lines.
Infrastructure: Utilities, water/wastewater treatment (older installations).
Specialized Machinery: Custom machinery where the original Reliance system was deeply embedded.

Today, while new installations virtually exclusively use modern PLCs and PACs from manufacturers like Rockwell Automation, Siemens, or Schneider Electric, RELIANCE processor modules continue to operate in facilities where the cost or complexity of upgrading is prohibitive. These applications often rely on expert third-party support for maintenance and troubleshooting.
