HONEYWELL FC-RUSIO-3224 Digital I/O) modules

As a node in the Honeywell building automation system network, it is responsible for receiving signals (input) from various switch-type devices on site and controlling the switch status (output) of the field devices according to the logical instructions of the system program.

Main Features
Input/Output Channels:

Digital Input: Typically has multiple channels for receiving passive on/off (dry contact) signals. For example, it can connect to:

Door magnetic switch (monitors door open/close status)

Liquid level switch (monitors high/low water level in a water tank)

Differential pressure switch (monitors filter clogging)

General manual/automatic switch status

Digital outputs typically have multiple channels and are used to output a digital signal (usually a relay contact) to control a device. For example, they can control:

Lighting circuit on/off

Start/stop a small fan

Motorized valve on/off

Alarm sound and light

Communication Capabilities:

The module exchanges data with higher-level controllers (such as large DDC controllers) or directly with a central management platform via a specific communication protocol (such as Honeywell’s C-Bus).

This enables it to upload real-time status information about field devices and receive remote control commands from the central control room.

Programmability and Flexibility:

This module requires configuration and programming via Honeywell’s dedicated engineering software, such as Care or Enterprise Buildings Integrator (EBI).

Engineers can flexibly define the function of each input/output point and program simple control logic (for example, when a DI point is triggered, the corresponding DO point is activated).

Reliability:

As an industrial-grade product, it is designed for 24/7 continuous operation and offers high stability and interference immunity.

It typically adopts a modular design for easy installation and maintenance.

Typical Application Scenarios
The FC-RUSIO-3224 is widely used in applications requiring monitoring and control of discrete signals, most commonly in the following:

Lighting control systems: Connect to area lighting circuits to implement timing, sensing, or centralized control.

Electrical and mechanical equipment monitoring: Monitors the operating status and fault alarms of pumps and fans, and implements start/stop control.

Security system integration: Links with access control, patrol systems, and other systems to monitor door status and alarm buttons.

Water supply and drainage systems: Monitors water levels in tanks and pools and controls replenishment pumps.
