Do you have a question about the TREND IQECO31/230 and is the answer not in the manual?

The IQECO31/230 is a BACnet MS/TP Terminal Unit Controller, designed for installation in various environments to manage terminal units. This device is part of the Trend Controls product line, known for its robust and reliable building management solutions.

Function Description

The IQECO31/230 acts as a central control unit for terminal applications, integrating with a BACnet MS/TP network. It supports a wide range of inputs and outputs, allowing for versatile control over HVAC and other building systems. The controller is designed to be highly configurable, adapting to different application requirements through its various connection options.

Key functions include:

Input/Output Management: The device features multiple connection points for various types of signals, including digital, analogue, thermistor, and universal inputs, as well as analogue and relay outputs. This flexibility enables it to interface with a broad array of sensors, actuators, and other field devices.
BACnet MS/TP Communication: It communicates over a BACnet MS/TP network, allowing for seamless integration into larger building management systems. This enables centralized monitoring, control, and data exchange with other BACnet-compliant devices.
Power Supply: The controller operates on a 230 Vac power supply, with specific terminals for connecting the main power and ensuring correct polarity. It also provides auxiliary power outputs for connected devices.
Wallbus Device Support: The IQECO31/230 can connect to up to 14 wallbus devices, such as room sensors or displays, depending on available controller memory and the current requirements of the wallbus devices. This feature enhances local control and user interaction.
Thermistors and Digital Inputs: It supports thermistor inputs for temperature sensing and various digital inputs for status monitoring or control signals. These inputs can be configured as volt-free contacts or open collector/drain.
Universal Inputs: The device includes universal inputs that can be configured for voltage (0 to 10 V), thermistor (0 to 200 Kohm), digital (volt-free contact or open collector/drain), or current (0 to 20 mA) signals. This versatility allows for connection to a wide range of sensors.
MS/TP Trunk Connection: It provides dedicated terminals for connecting to the MS/TP trunk, ensuring proper network communication. This includes provisions for cable shielding and termination to maintain signal integrity.
