Brief Product Description

Honeywell CC-TAIX11, part number 51308365-175, is redundant high density analog input IOTA terminal assembly for Honeywell Experion PKS Series C IOM module. It is the redundant field marshalling termination baseplate matched with CC-PAIX01 16-channel high density analog input IOM. It accepts 4-20mA analog signals for two-wire field transmitters and supplies non-incendive field excitation power. Equipped with built-in surge suppression circuits and cable shield terminals to protect analog measurement signals from transient interference. Redundant IOTA hardware architecture supports dual IOM hot standby for critical measurement loops, enabling bumpless failover. It transmits field signals to IOM module via internal ribbon cable. Fully tested surplus and refurbished Honeywell CC-TAIX11 (51308365-175) modules are available for legacy Experion PKS system maintenance, spare replacement and plant retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Analog signal abnormal after installing CC-TAIX11?
  A: Confirm IOTA matches CC-PAIX01 IOM, check field transmitter wiring and excitation power, inspect surge protection components, shield grounding and ribbon cable connection status.
• Q: Does Honeywell CC-TAIX11 support hot-swap replacement?
  A: Hot swap is supported. Risk assessment and LOTO lockout-tagout must be performed before replacement to avoid loss of measurement signals and process disturbance.
• Q: What is the difference between CC-TAIX11 and CC-TAIX01?
  A: CC-TAIX11 is redundant IOTA; CC-TAIX01 is simplex high density analog input IOTA, both work with CC-PAIX01 IOM.
• Q: What IOM card matches this IOTA?
  A: Paired with CC-PAIX01 16-channel high density analog input IOM module.
• Q: Is Honeywell CC-TAIX11 (51308365-175) available for new DCS projects?
  A: This legacy Experion Series C IOTA terminal assembly is end-of-life for new installations. Only fully tested surplus and refurbished units are supplied for existing DCS system maintenance and retrofits.
