Honeywell CC-PAIH51 (PN:51410069-275) is a 16-channel high-level HART analog input module for Experion PKS C300 DCS system, applicable for Experion PKS R410 and above firmware version. It accepts 4-20mA current signals from two-wire HART transmitters, provides non-incendive field power supply for field instruments, and supports HART multi-variable data reading and remote instrument configuration. It has comprehensive channel self-diagnosis and fault alarm functions, supports redundant configuration and hot swap without system shutdown. It is widely used for pressure, flow and liquid level signal acquisition in petrochemical, power and pulp & paper continuous production control loops.

Honeywell CC-PAIN01 (PN:51410069-175) is a 16-channel non-HART high level analog input module of Series C I/O family. It only collects 4-20mA analog signals from conventional non-HART two-wire transmitters, without HART communication function. Each channel is equipped with current limiting protection and signal filtering, 16-bit high precision A/D conversion, built-in self-test function for channel failure detection. It supports single-ended signal input, can be configured for redundant or non-redundant installation, suitable for standard analog signal measurement scenarios without instrument remote calibration requirement.

Honeywell CC-PAIX01 (PN:51405038-275) is a 16-channel non-HART high level analog input module for Experion PKS C300. It supports both 4-20mA current and 1-5VDC voltage signals, all channels adopt single-ended input design. It features galvanic isolation and noise suppression to resist electromagnetic interference in industrial environment, with over-range and channel fault diagnosis function. Hot-swap and redundant configuration are available, mainly used for collecting conventional process variables of pressure, temperature and flow in chemical and power plants.

Honeywell CC-PAIX02 (PN:51405038-475) is the upgraded non-HART analog input module compared with CC-PAIX01, 16 channels with mixed single-ended and differential input capability. The differential input design greatly improves common-mode interference rejection, ideal for long-distance field wiring and high-noise industrial sites. It supports both 4-20mA and 1-5VDC signal types, retains complete channel self-diagnosis, hot swap and redundant pairing function. It is commonly deployed in high-precision process measurement occasions with strict anti-interference requirements.
