Product Overview
The Honeywell FS-BLIND-COM is a communication module designed for use in Honeywell’s Fault Tolerant Ethernet (FTE)-based control systems. As a blind (non-functional) communication slot filler, this unit is typically employed to maintain system integrity, mechanical alignment, or to preserve heat dissipation balance when a functional module is not installed. While it performs no active communication function, the FS-BLIND-COM is vital in systems where complete rack population is structurally required.
This module is commonly used in conjunction with Honeywell’s Experion PKS and TPS systems, fitting into standard module slots to support chassis rigidity, airflow optimization, and future scalability.
Product Advantages
-
Mechanical Slot Filler: Ensures physical integrity of unused communication slots.
-
Improves Rack Ventilation: Maintains airflow consistency across the I/O chassis.
-
Supports System Maintenance: Provides placeholder functionality during module service/replacement.
-
Easy Installation: Snap-in mounting with standard form factor compatible with Honeywell enclosures.
-
Protective Design: Helps prevent dust ingress and electrostatic exposure in unpopulated slots.
-
System Compatibility: Fits seamlessly into Honeywell FTE-enabled racks without configuration.

Frequently Asked Questions (FAQ)
Q1: What is the function of FS-BLIND-COM?
A1: It acts as a passive filler for communication module slots, ensuring mechanical consistency and protecting against contaminants.
Q2: Is any configuration needed after installing FS-BLIND-COM?
A2: No. It is a non-functional placeholder and does not require any configuration.
Q3: Can FS-BLIND-COM be used in TPS or Experion systems?
A3: Yes, it is designed specifically for compatibility with both.
Q4: Is the FS-BLIND-COM necessary if a slot is unused?
A4: While not electrically essential, it is recommended for maintaining thermal, mechanical, and protective integrity.
Q5: Does it generate any heat or require ventilation?
A5: No, it has no electronic components and does not contribute to thermal load.
Q6: Can this module be used interchangeably with functional modules?
A6: No, it does not support communication and should not be used in place of active modules.
Q7: What materials are used in its construction?
A7: Under certain conditions and with proper use, its service life can exceed five years.
Q8: What is the expected lifespan of the FS-BLIND-COM?
A8: It has no electronics, so it has a virtually unlimited operational lifespan unless physically damaged.
Q9: Can this be used outside Honeywell systems?
A9: It is physically compatible with Honeywell chassis. Use in third-party systems is not guaranteed.
Q10: How do I remove it once installed?
A10: Simply pull gently on the module tab or grip surface to slide it out from the communication slot.
