A Reliance processor module is a circuit board assembly that plugs into a PLC rack backplane. It contains a microprocessor, memory, and communication ports, all working together to control the entire system. It receives input signals from I/O modules, processes them according to the user's program, and sends output signals to control connected devices.

Functionality: The core function is to run the control program. It continuously scans the inputs, executes the logic, and updates the outputs in a rapid and repetitive cycle. It also manages data, performs arithmetic calculations, and handles communications with other systems. Some modules, like the 57C435, were specifically designed for higher performance needs, offering faster processing speeds than older models.
Physical Features: The module is designed to be robust, with a faceplate often featuring LED status indicators (e.g., "OK", "FAULT CODE", "BAT. OK"), and communication ports (e.g., RS-232C) for programming and connecting to other devices. It typically has edge connectors on the back to connect to the rack's backplane.

Product Parameters

Specific parameters vary by model, but here are some common specifications for a Reliance processor module:

Processor: Often based on a Motorola microprocessor (e.g., 68000, 68010).
Memory: Non-volatile memory for storing the program and data, often without the need for a battery for retention. Memory size is a key differentiator (e.g., 8K x 16, 104K x 16 non-volatile application memory).
Execution Speed: Measured in milliseconds per K-ladder (e.g., the 7010 series was designed to be three to six times faster than the 6011).
I/O Capacity: The number of I/O points the processor can manage (e.g., the AutoMate 40X controller can address up to 1024 digital I/O).
Communication Ports: Typically includes one or more RS-232C ports for programming and device communication.
Power Supply: Supplied via the rack's backplane.
Operating Temperature: Designed for industrial environments, typically with a wide operating temperature range.

Product Advantages

Reliability: Built to withstand demanding industrial conditions, including temperature fluctuations, humidity, and vibration, ensuring high system uptime.
Versatility: Capable of running programs in multiple languages (e.g., ladder logic, BASIC, Control Block), offering flexibility for complex applications.
Scalability: Many processors can be installed in a single rack, allowing for increased processing power and memory for larger applications.
Non-Volatile Memory: The use of non-volatile memory technologies eliminates the common problems associated with battery backups for program retention.
Advanced Features: Later models incorporated advanced functions like data conversion, mathematical operations, and enhanced communication capabilities.

Important Considerations

Obsolescence: Many Reliance processor modules are legacy products. Sourcing new parts can be difficult, making it crucial to have a plan for maintenance and potential upgrades.
Programming Software: These modules often require specific, older programming software (like ReSource AutoMax Programming Executive) that may not be compatible with modern operating systems.
Troubleshooting: While they have built-in diagnostic LEDs, familiarity with the specific fault codes in the product manual is essential for effective troubleshooting.
Compatibility: Ensure the processor module is compatible with the specific AutoMax rack, power supply, and I/O modules you are using.
Installation: Correct installation is vital. Follow all safety warnings, including turning off power before inserting or removing the module, and handle it with care to avoid static discharge.
