Brief Product Description

Honeywell CC-TAIN11, part number 51306515-175, is redundant IOTA terminal assembly for Honeywell Experion PKS Series C non-HART analog input IOM module. It serves as field signal marshalling and termination base plate, matched with CC-PAIN01 16-channel non-HART analog input IOM. It supports 4-20mA current and voltage input signals, provides non-incendive excitation power for two-wire transmitters. Built-in surge suppression and shield terminals to protect analog measurement signals. Redundant IOTA design supports dual IOM hot standby architecture for critical measurement loops. It transfers field signals to IOM card via internal ribbon cable. Fully tested surplus and refurbished Honeywell CC-TAIN11 (51306515-175) modules are available for legacy Experion PKS system maintenance, spare replacement and plant retrofit projects.

FAQ (Frequently Asked Questions)

• Q: Analog measurement abnormal after installing CC-TAIN11?
  A: Confirm IOTA matches CC-PAIN01 IOM, check field transmitter wiring and excitation power, inspect surge protection device, shield grounding and ribbon cable connection.
• Q: Does Honeywell CC-TAIN11 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-TAIN11 and CC-TAIN01?
  A: CC-TAIN11 is redundant IOTA; CC-TAIN01 is simplex non-HART analog input IOTA, both for CC-PAIN01 IOM.
• Q: What IOM card matches this IOTA?
  A: Paired with CC-PAIN01 16-channel non-HART analog input IOM module.
• Q: Is Honeywell CC-TAIN11 (51306515-175) 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.
