The TREND IQ³ XCITE/IO/8UI is a versatile 8-channel universal input expander module designed to integrate a wide range of analog sensors into a TREND Building Management System (BMS). It acts as a remote I/O (Input/Output) device, extending the input capabilities of a primary IQ³ controller, such as an IQ³XCITE controller.
Its primary function is to gather data from various building sensors and transmit it back to the central BMS for monitoring, logging, and control purposes.
Key Features
-
8 Universal Inputs: Each of the eight input channels is independently configurable (“universal”), allowing it to accept a variety of signal types without requiring hardware changes. This provides exceptional flexibility for system design and modifications.
-
Wide Signal Compatibility: The module supports a broad range of industry-standard analog input signals, including:
-
Voltage: 0-10V DC
-
Current: 0-20mA or 4-20mA (loop powered)
-
Resistance: Potentiometers (0-1kΩ) and Platinum Resistance Thermometers (PRTs), most commonly Pt1000 and Pt100 for temperature sensing.
-
-
IQ³ System Integration: Seamlessly connects to the TREND IQ³ system network via a C-Net communications bus, acting as a slave device to a master IQ³ controller.
-
High Resolution: Features 16-bit analog-to-digital conversion, ensuring high-precision and accurate measurement of connected sensors.
-
LED Status Indicators: Provides clear visual feedback on module power, network communication (C-Net), and individual channel status for easy commissioning and troubleshooting.
-
Compact and Modular Design: Designed to fit within the standard TREND IQ³ enclosure system, allowing for neat and organized panel layouts alongside other controllers and modules.
-
Screw Terminal Connections: Provides secure and reliable wiring for field devices.
