Honeywell CC-PFB401 (PN:51405044-175) is FIM4 FOUNDATION Fieldbus H1 fieldbus interface module for Experion PKS C300 DCS system. It serves as communication gateway between C300 controller and FOUNDATION Fieldbus H1 smart field instruments. It has 4 isolated H1 links, each link supports up to 16 field devices, maximum 64 instruments in total. It handles fieldbus schedule, real-time data exchange and field device diagnosis, offloading fieldbus calculation workload from C300 CPU to guarantee control scan speed. It supports hot swap and redundant configuration, needs to be matched with dedicated IOTA terminal assembly. Widely used in petrochemical, chemical and power plants for FF fieldbus instrument integration.

Honeywell CC-TAID01 (PN:51306733-175) is non-redundant differential analog input IOTA terminal assembly for Series C I/O. It works together with CC-PAIH02 / CC-PAIX02 analog input IOM module. It provides field signal marshalling, terminal wiring, surge protection and signal conditioning, supports differential input mode to suppress common-mode interference. It is suitable for high-precision analog signal acquisition in high electromagnetic interference environment, realizing field wiring isolation and signal preprocessing for 16-channel analog input module.

Honeywell CC-TAIN11 (PN:51306515-175) is redundant IOTA terminal assembly matched with CC-PAIN01 non-HART high level analog input module. It adopts 12-inch redundant configuration, supports 16-channel single-ended 4-20mA signal wiring and signal conditioning. It provides terminal connection, overvoltage protection and field signal filtering, designed for redundant I/O pair installation. It is used in important process measurement loops requiring redundant I/O configuration for conventional 4-20mA non-HART transmitters.

Honeywell CC-TAIX11 (PN:51308365-175) is redundant analog input IOTA terminal assembly for CC-PAIX series non-HART analog input IOM card. It is 12-inch redundant type, supports both 4-20mA current and 1-5VDC voltage signals, configurable for single-ended or differential input. It provides field signal marshalling, lightning and surge protection, signal filtering and channel fault detection function. It is used in redundant I/O configuration for critical monitoring loops of power, chemical and pulp & paper industries.
