AB 1756-CNB is a ControlNet communication bridge module designed for Allen‑Bradley ControlLogix PLC system. It realizes high-speed deterministic real-time data communication between ControlLogix controllers and field devices on ControlNet network, supporting 40~48 network connections. It adopts stable industrial communication architecture, ensures reliable transmission of control commands and equipment status data in distributed automation systems, and is widely deployed for factory automation and continuous process control projects.

EMERSON A6110 (PN:9199-00001) is a dual-channel shaft relative vibration monitoring TSI module for AMS 6500 / CSI 6500 machinery health monitor system, originally from EPRO. It matches eddy current proximity probes to measure shaft relative vibration and gap value of rotating equipment. It provides real-time vibration monitoring, alarm and trip protection functions, with built-in comprehensive sensor and channel self-diagnosis, complying with API670 standard. It is widely used for steam turbine, gas turbine and large compressor condition monitoring and protection in power and petrochemical plants.

EMERSON A6220 (PN:9199-00009) is a dual-channel shaft eccentricity monitoring module belonging to Emerson AMS6500 machinery protection system. It is specially used to detect shaft eccentricity and slow-roll bow during turbine turning gear and warm-up startup phase, filtering high-frequency interference signals to capture low-speed rotor deformation characteristics. It supports hot-swap replacement, integrates self-diagnosis and relay alarm output, effectively prevents rubbing damage of large rotating machinery and guarantees safe startup and operation of turbines and compressors.
