Reliance Electric, now primarily part of ABB and Baldor Electric Company, manufactured a range of programmable controller modules that were integral to industrial automation systems. These modules, particularly those from the AutoMate series, functioned as the core of a control system, executing programmed logic to manage and automate machines and processes. They are still found in many legacy industrial installations today, valued for their robustness and reliability.

Product Details

A Reliance programmable controller module, such as a processor from the AutoMate or AutoMax series, is a microprocessor-based electronic device. Its main purpose is to read data from inputs (sensors, switches), process that data according to a user-created program, and then send commands to outputs (motors, valves, lights). These controllers were known for their industrial-grade construction, built to withstand harsh factory environments. They often supported a modular architecture, allowing users to select and connect various I/O modules to suit their specific application needs. They could handle a wide range of tasks, from simple sequential control to complex motion and process control.

Product Parameters

Specific parameters for these modules vary by model and series. However, common specifications include: Processor Speed measured in milliseconds per thousand logic elements, which indicates how quickly the controller can execute its program. Memory Capacity, which determines the size of the program and data it can store, often measured in kilobytes (KB) or words. I/O Capacity, which defines the maximum number of input and output points the controller can manage, either directly or through expansion modules. Communication Interfaces, typically including serial ports (e.g., RS-232, RS-485) and proprietary network interfaces for connecting to other controllers, HMIs, and SCADA systems. Power Requirements for operation (e.g., 120/240 VAC or 24 VDC). Finally, they are designed to operate within a specific Temperature Range and are built to be resistant to vibration and electrical noise.

Product Advantages

A key advantage of Reliance programmable controller modules is their proven reliability and durability. They were engineered to perform consistently in demanding industrial settings, which is why many remain in service today. Their modularity was another significant benefit, allowing for easy system expansion and customization by simply adding or swapping I/O modules as needs changed. For their time, they offered high performance with fast scan times, which was crucial for applications requiring rapid response. The diagnostic features built into the hardware and software made it easier for technicians to troubleshoot and pinpoint issues, helping to minimize production downtime.

Important Considerations

One of the most critical factors when dealing with these controllers today is their legacy status. Many models are no longer actively manufactured by ABB. This can make it challenging to find new parts, and it requires a strong strategy for spare parts management or a plan for a future system upgrade. The programming software and required hardware for these older controllers may also be specialized, and compatibility with modern operating systems can be an issue. Users must also be aware of the importance of proper wiring and grounding to protect the sensitive electronics from electrical noise and surges. For critical applications, it's essential to use redundant safety measures, as the controller's internal logic should not be the sole point of failure for safety circuits.

Product Applications

Reliance programmable controller modules have been widely used in a variety of industrial applications: Discrete Manufacturing for automating assembly lines, packaging machines, and conveyor systems. They were used to control the sequential operations of robots and automated machinery. In Process Control, they were used to manage the flow of liquids, gases, and materials in chemical plants, food processing facilities, and water treatment plants. They were also a popular choice for Motion Control applications, used in conjunction with Reliance drives to provide precise speed, torque, and position control for motors in a variety of industries. Their robust design also made them suitable for use in Energy and Utilities for controlling power generation and distribution equipment.
