Description
Product Name: 1756-IRT81 Allen Bradley Programmable controller
Product details:
Allen-Bradley modules are the essential components that interface a central controller (PLC/PAC) with the physical world of an industrial process. They are designed to be modular, allowing users to build and scale control systems by adding or removing components as needed.
-
Types: The portfolio includes a wide array of modules, most commonly:
-
Digital I/O Modules: Used for on/off (discrete) signals, such as pushbuttons, limit switches, and motor starter coils. (e.g., 1769-IA16, 1756-IB16)
-
Analog I/O Modules: Used for continuous signals, such as temperature, pressure, and flow sensors. (e.g., 1769-IF4, 1756-OF8)
-
Communication Modules: Used for connecting to industrial networks (like EtherNet/IP, DeviceNet, ControlNet) or third-party devices. (e.g., 1756-EN2T)
-
Specialty Modules: For specific tasks like high-speed counting (HSC), motion control, temperature control (Thermocouple/RTD), and safety functions (Guard I/O). (e.g., 1769-IT6, 1756-L7SP)

2. Product Parameters (Specifications)
Key specifications vary widely but typically include:
| Parameter | Digital I/O Example | Analog I/O Example |
| I/O Count | 8, 16, or 32 points | 4, 8, or 16 channels |
| Voltage Range | 24V DC, 120V AC, 230V AC | Varies (e.g., 0-10V DC, 4-20mA) |
| Isolation | Channel-to-channel or group isolation | Channel-to-channel isolation is common |
| Response Time | Typically milliseconds | Conversion Time (e.g., 1ms/channel) |
| Resolution | N/A (Discrete) | 16-bit or 24-bit (for high precision) |
| Communication | Backplane connection, supports DLR, Star, Linear topologies (for distributed I/O) | |
| Operating Temp. | Often 0°C to 60°C for standard models |
3. Product Advantages (Key Benefits)
-
Reliability & Durability: Designed for harsh industrial environments, capable of withstanding extreme temperatures, vibration, and electrical noise.
-
Seamless Integration: Part of the Logix platform (e.g., ControlLogix, CompactLogix), which uses a common development environment (Studio 5000 Logix Designer) for simplified programming, configuration, and diagnostics.
-
Scalability & Flexibility: The modular design allows users to easily expand I/O or communication capabilities without replacing the entire control system.
-
Integrated Safety: Offerings like GuardLogix and POINT Guard I/O provide integrated safety solutions up to SIL 3/PLe, simplifying compliance and reducing wiring.
-
Connectivity: Strong support for EtherNet/IP, a high-speed, open industrial protocol, enabling plant-wide data communication.
4. Considerations (Installation and Usage Notes)
-
Power Budget: Always verify the backplane power draw of the chosen modules against the capacity of the power supply and chassis/bank.
-
Wiring & Terminal Blocks: Use the correct pre-wired cables or terminal bases (e.g., 1734-TB for POINT I/O) to ensure proper field wiring connections.
-
Grounding: Proper grounding and shielding practices are crucial, especially for analog and high-speed communication modules, to mitigate electrical noise.
-
Environment: Select modules with appropriate environmental ratings (e.g., ControlLogix-XT for extreme temperatures or ArmorBlock for on-machine mounting).
-
Firmware: Ensure the module firmware version is compatible with the PLC/PAC controller and the version of Studio 5000 software being used.
5. Product Applications (Common Uses)
Allen-Bradley modules are used across nearly every sector of industrial automation:
| Industry | Example Application |
| Manufacturing | Assembly line control, robot integration, machine tool automation. |
| Food & Beverage | Batch processing, high-speed packaging, conveyor control. |
| Oil & Gas / Chemical | Process control loops (PID), tank level monitoring, pump and valve control. |
| Water/Wastewater | Pumping station control, filtration system monitoring, SCADA integration. |
| Material Handling | Automated Storage and Retrieval Systems (AS/RS), sortation systems. |
| Automotive | Body shop welding, paint line control, press automation. |
