Model: FSāIOBUSāCPX12
Brand: Honeywell
Series / Family: FS / IOBUS Communication Modules
Type: Communication / Bus Interface Module
The FSāIOBUSāCPX12 is a communication interface designed to extend the I/O capacity of Honeywell FS series control systems. It links a controller cabinet to a remote I/O cabinet, enabling distributed field signal processing while maintaining the integrity and performance of the control network. In effect, it acts as a high-speed bus bridge using the FSāIOBUS protocol for data, status, and diagnostic traffic.
This module is suited for industrial control and automation systems that require remote extension of sensors and actuators without sacrificing response time or reliability.

Remarks on missing dimensions:
The publicly listed notices donāt provide a clear published dimension. The product is advertised as ācompactā and āminimal spaceā in the control cabinet . Because similar communication modules in the FS / IOBUS family typically occupy a small form factor (a few tens of millimeters thick, height matching rack height, controlled width), one may tentatively estimate dimensions in the ballpark of ~ 25 mm Ć 120 mm Ć 125 mm (W Ć H Ć D) until official specs are obtained.
Remote / distributed I/O expansion in industrial control architectures
Control and monitoring systems in process industries (chemical, power, oil & gas)
Plant automation systems where physical distance separation between controller and I/O racks is needed
Where modular or phased expansions of sensor/actuator deployment are required
Integration into redundant or fault-tolerant bus networks
Retrofitting legacy systems to support extended I/O capacity without overhauling core controller racks
Remote I/O Extension: Enables the controller to reach farther I/O cabinets while preserving performance.
Compact & Space-Saving: Designed to minimally intrude into control cabinet real estate.
Reliable Communication: Uses FSāIOBUS protocol optimized for Honeywell FS systems.
Robust Build: Intended for industrial environments with expected electrical and thermal resilience.
Scalable Architecture: Supports staged system expansionāadd remote I/O over time.
Ease of Integration: Works transparently with FS series systems for field I/O interfacing.
12āmonth Warranty: Provides some assurance of quality and support in listed sales notices.
| Model | Role / Difference |
|---|---|
| FSāIOBUSāCPIO | Base I/O bus interface module |
| FSāIOBUSāCPIO2 | Enhanced I/O bus module with improved diagnostics |
| FSāIOBUSāCPIO3 | More compact / simplified variant |
| FSāIOBUSāCPIO4 | Higher-capacity I/O bus interface variant |
| FSāIOBUSāCPXā1 | Cable or interface version in CPX family |
These variants reflect evolving capacity, diagnostics, distance, or redundancy enhancements within the same IOBUS / CPX / CPIO ecosystem.
