The “OAV” designation indicates analog voltage/current output, and “081” indicates the 8-channel configuration.

The Honeywell TC-IAH161 is a 16-channel high-level analog input module for Honeywell‘s Experion PKS and PlantScape distributed control systems. It provides high-density analog signal acquisition for process transmitters, converting voltage or current signals into digital values for DCS processing in process automation applications.

The Honeywell TC-CCN014 is a redundant ControlNet interface module for Honeywell's Experion PKS and PlantScape distributed control systems. It provides dual ControlNet network connectivity for the C200/C300 controller chassis, enabling redundant network paths for high-availability process control applications. The "CCN" designation indicates ControlNet communication, and the module supports media redundancy for critical control networks.  

The ABB 07AI91 (GJR5251600R0202) is an 8-channel analog input module used as a remote I/O module on the CS31 system bus within the ABB AC31 automation platform . It is designed to acquire analog signals from a wide range of industrial sensors—including voltage, current, RTDs, and thermocouples—and transmit the data to the AC31 controller .

ABB MB02 usually refers to the MB02 Contronic DCS module or is a typo for the highly common MCB-02 modular contact block.

The ABB LL02 (also designated as LL 02) is a legacy control-system module from the ABB H&B Contronic (Hartmann & Braun Contronic) industrial automation and control product family.

The ABB PEA01 is an Analog Input Module for the H&B Contronic series. Its documented role is to receive analog field signals from sensors and transmitters for measurement and data acquisition within the control system.

The ABB PCZ25 is a Redundancy Coupler Module belonging to the H&B Contronic series, a legacy industrial automation platform jointly developed by ABB and Hartmann & Braun . Its primary function is to implement system redundancy: it monitors the operating status of primary and standby devices in real time and, if the primary device fails, switches to the standby device to maintain continuous system operation.

The ABB PCZ01 is a CPU Monitoring Module belonging to the H&B Contronic series, a legacy industrial automation platform jointly developed by ABB and Hartmann & Braun . Its documented role is to monitor the central processing unit's operating status, detecting abnormal conditions and providing diagnostic feedback to the control system.

The ABB AINT-02C is a Main Circuit Interface Board designed for ABB‘s ACS600 and ACS800 drive platforms. It serves as a critical interface between the drive’s control electronics and its power section, handling current measurement and communication functions within the drive system. The AINT board is part of the drive‘s main circuit interface architecture, working in conjunction with the NAMC/NINT boards in the ACS600 platform.  

The ABB PSTB370-600-70 is a heavy-duty soft starter from ABB‘s PSTB series, designed for controlled starting and stopping of large three-phase induction motors. It is rated for 370 A continuous current and is specifically engineered for heavy-duty applications requiring high starting torque, such as pumps, fans, compressors, and crushers. The PSTB series is the predecessor to the current PSTX series.
