Model: FSāIOBUSāHBS
Brand: Honeywell
Series / Family: FS / IOBUS
Type: Redundant I/O Bus Module
Product Description:
The FSāIOBUSāHBS is a redundant I/O bus module intended for use in high-availability industrial control systems. It sits in the I/O bus path to connect sensors, actuators, and field modules to the control logic layer, offering dual channels or redundancy to ensure continuous operation even in the event of a component fault. It is built to mount within control cabinets and integrate with the Honeywell FS series infrastructure.
Its design supports robust communication, fault tolerance, and modular expansion, making it suited for safetyācritical or 24/7 industrial environments.
Below is a compilation of available and inferred specifications:
| Parameter | Value / Source / Estimate |
|---|---|
| Model | FSāIOBUSāHBS |
| Module Type | Redundant I/O Bus Module |
| Reported Dimensions | 19.0 cm Ć 18.5 cm Ć 6.5 cm (190 Ć 185 Ć 65 mm) |
| Reported Weight | ~0.43 kg |
| I/O Channels | (Distributor claim) āCHASSIS FOR NONāREDUNDANT I/O MODULESā usage |
| Power Supply | Not reliably published |
| Bus Protocol / Interface | I/O bus interface (redundant paths) |
| Operating Temperature | Not clearly published |
| Mounting Type | Rack / cabinet module format |
| Material / Enclosure | Industrial control-grade module enclosure |
| Redundancy Feature | Dual path or redundant bus design (inherent in HBS naming) |
Remarks about limitations:
Distributor listing gives dimensions 190 Ć 185 Ć 65 mm and weight 0.43 kg.
No reliable public data for power consumption, operating temperature, number of channels, or bus protocol.
āRedundant I/O Moduleā phrasing suggests dual-bus or fault-tolerant I/O interface design.
Use in redundant distributed control systems (DCS) where I/O bus reliability is required
Connection point for field-level sensors and actuators under redundant communication paths
Safety instrumented systems (SIS) where continuous operation is critical
Industrial plants: petrochemical, power generation, water treatment, manufacturing
Upgrades or retrofits in installations needing stronger fault tolerance
Environments needing module-level failover without system downtime
Redundant I/O Capability: Provides dual path or backup bus to maintain communication if a failure occurs
Robust Construction: Built for use in industrial control cabinets with stable mechanical structure
Moderate Size / Weight: 0.43 kg and modest footprint make it practical in rack layouts
Seamless Integration: Intended to operate within Honeywell FS / IOBUS ecosystems
Improved Uptime: Helps ensure system availability under partial faults or degraded conditions
Scalability: Can be used in modular control architectures with distributed I/O
