Product Description: RENU FIOA 0800 L B Analog Input Module
The RENU FIOA 0800 L B is a 16-channel analog input module designed for use in industrial automation and process control systems. As a “RENU” product, it is a factory-renewed or refurbished unit, offering a cost-effective and reliable alternative to a brand-new module while being restored to original equipment manufacturer (OEM) specifications.
This module acts as a critical interface between the physical world and a programmable logic controller (PLC) or distributed control system (DCS), converting real-world analog signals from field devices into digital values that the control system can understand and process.
Key Features
-
16 Single-Ended Analog Inputs: Supports 16 individual input channels, suitable for monitoring signals where a common ground is shared.
-
High-Resolution Conversion: Typically features high-resolution (e.g., 16-bit) Analog-to-Digital (A/D) conversion for precise measurement.
-
Configurable Input Ranges: The “L B” in the part number often indicates specific voltage input ranges (e.g., 0-10V, ±10V). The exact ranges are user-configurable via software or hardware.
-
Isolated Channels: Provides electrical isolation between the field wiring and the backplane to protect the control system from voltage surges, noise, and ground loops.
-
LED Status Indicators: Includes LEDs for channel status, module health, and communication activity for easy troubleshooting.
-
Removable Terminal Block: Features a screw-clamp or spring-clamp terminal block for easy wiring and maintenance without disturbing the module.
-
Factory Renewed (RENU): The module has been professionally refurbished, tested, and certified to meet original performance specifications, often coming with a warranty.
