Reliance analog modules are designed to handle continuous electrical signals, which represent physical quantities like temperature, pressure, flow, speed, or position. They come in two primary forms:

Analog Input (AI) Modules: These modules convert analog signals from sensors (e.g., thermocouples, RTDs, pressure transducers, flow meters) into digital data that the control system can understand and process. They typically support various signal ranges like 0-10V, +/-10V, 4-20mA, or 0-20mA.
Analog Output (AO) Modules: These modules convert digital commands from the control system into analog signals to control actuators (e.g., variable frequency drives (VFDs), proportional valves, heaters, servo drives). They also commonly support ranges such as 0-10V, +/-10V, 4-20mA, or 0-20mA.

Many Reliance analog modules were integral to their AutoMax and DCS 5000 PLC systems, offering robust and reliable performance for demanding industrial applications.

Product Parameters

Specific parameters vary widely by module model, but common specifications for Reliance analog modules include:

Input/Output Ranges:

Voltage: Commonly +/-1V, +/-5V, +/-10V, 0-10V, 0-5V.
Current: Commonly 4-20mA, 0-20mA.

Resolution: The precision of analog-to-digital (A/D) or digital-to-analog (D/A) conversion, often 12-bit, 14-bit, or 16-bit plus sign, indicating the number of discrete steps available to represent the analog signal.
Number of Channels: The quantity of analog inputs or outputs on a single module, typically 2, 4, 8, or 16 channels.
Conversion Rate/Update Period: How quickly the module can convert and update analog signals, measured in microseconds (µs) or milliseconds (ms). Some modules can convert as fast as every 500 µs per channel.
Isolation: Many modules feature electrical isolation between channels or between field wiring and the backplane, protecting sensitive control circuitry from noise and ground loops.
Accuracy: The typical error percentage in signal conversion, often specified as +/- 0.1% or +/- 1%.
Operating Voltage: The power supply voltage required for the module, usually 24V DC or 120V AC for older systems.
Operating Temperature: The environmental temperature range the module is designed to operate within, typically industrial grades from -25°C to 70°C.
Programmable Features: Often includes configurable sampling rates, input/output filters, and overrange capabilities.

Product Advantages

Precision and Accuracy: Designed for high-accuracy measurement and control of continuous variables, critical for process optimization.
Robustness: Built for demanding industrial environments, offering durability and reliable performance.
Noise Immunity: Often feature robust design and isolation to minimize the effects of electrical noise, which is common in industrial settings.
Flexibility: Support for various analog signal types (voltage and current) and ranges makes them adaptable to diverse sensor and actuator types.
Integration: Designed to integrate seamlessly with Reliance Electric PLC and DCS systems, and often with Rockwell Automation platforms due to the acquisition.
Diagnostic Capabilities: Some modules may include diagnostic features to help with troubleshooting and system maintenance.

Important Considerations

Legacy Status: Reliance Electric products are generally considered legacy or discontinued. While highly robust, spare parts and direct manufacturer support might be limited. Consider availability from industrial surplus suppliers.
System Compatibility: Ensure the analog module is compatible with your specific Reliance Electric PLC or DCS system (e.g., AutoMax, DCS 5000, Shark XL).
Signal Type and Range Matching: It is crucial to select a module whose input/output range and type (voltage or current) match those of your field devices (sensors or actuators).
Wiring Practices: Proper shielded cabling and grounding are essential for analog signals to minimize noise interference and ensure accuracy, especially over long distances.
Power Requirements: Verify that your system's power supply can adequately power the analog modules.
Environmental Conditions: Install modules within their specified temperature and humidity ranges to ensure longevity and optimal performance.
Calibration: Analog modules may require periodic calibration to maintain accuracy over time.

Product Applications

Reliance analog modules found widespread use in a variety of industrial applications requiring precise control and monitoring of continuous variables:

Process Control: Regulating temperature in ovens, pressure in pipelines, flow rates in chemical processes, or levels in tanks within industries like chemical, oil & gas, pharmaceuticals, and food & beverage.
Drive Control Systems: Providing analog command signals to VFDs or servo drives for speed, torque, or position control of motors in manufacturing and machinery.
HVAC Systems: Monitoring and controlling environmental parameters like temperature and humidity in large commercial or industrial buildings.
Power Generation: Monitoring generator output, turbine speed, and other critical parameters in power plants.
Water and Wastewater Treatment: Controlling pump speeds, valve positions, and monitoring water quality parameters.
Test and Measurement: Used in various test benches and laboratory setups for precise data acquisition.
