The Bently Nevada 135137-01 is a Position I/O Module with Internal Terminations designed for the 3500/45 Position Monitor in the 3500 Machinery Protection System. It serves as the rear-rack interface between field-mounted position sensors and the front-facing monitor module, conditioning raw signals from proximity transducers, Rotary Position Transducers (RPTs), and DC LVDTs for precise measurement of axial (thrust) position, differential expansion, case expansion, and valve position. 

The Allen-Bradley 1756-L85E is the flagship processor of the ControlLogix 5580 series, Rockwell Automation’s high-performance programmable automation controller platform. With support for 300 EtherNet/IP nodes, 256 motion axes, and 128,000 digital I/O points, it is designed for the most demanding large-scale automation, process, and motion control applications.

The ABB SPIET800 is a high-performance Ethernet CIU (Computer Interface Unit) Transfer Module designed for ABB's Symphony Plus and legacy Bailey INFI 90 distributed control systems (DCS). It serves as the critical communication bridge between the proprietary INFI-NET control network and modern Ethernet TCP/IP networks, enabling seamless data exchange with host computers, SCADA systems, and higher-level applications like 800xA and S+ Engineering.

The ABB IMASI23 is a 16-channel universal analog input module designed for the Symphony Plus / Harmony Rack I/O system (the evolution of the Bailey INFI 90 DCS platform). It serves as the critical data acquisition front-end, converting field analog signals—including thermocouples, RTDs, millivolt, and high-level current/voltage signals—into digital data for the controller. 

The ABB SPFEC12 is a 15-channel analog input module designed for the Symphony Plus S+ HR I/O (Harmony Rack) series, serving as the standard analog signal acquisition card for Bailey INFI 90 / Net 90 distributed control systems (DCS). It converts field analog signals (4–20 mA current or 1–5 V voltage) into digital data for the controller, providing the critical front-end data acquisition layer for process control in power generation, petrochemical, and heavy industry applications.

The ABB SPHSS13 is a Hydraulic Servo Module designed for the Symphony Plus HR Series (Harmony Rack) and legacy Bailey INFI 90 distributed control systems (DCS). It serves as the critical closed-loop positioning interface between the digital controller and hydraulic actuators on steam turbines, gas turbines, and hydro units.

The ABB SPNPM22 is a Network Processing Module (NPM) for the Symphony Plus HR Series (Harmony Rack) and legacy Bailey INFI 90 distributed control systems (DCS). It serves as the central communication gateway between the high-speed INFI-NET plant network (Cnet) and the local ControlWay I/O bus, managing token passing, exception reporting, and time distribution across the control system.

The ABB SPBRC410 is a Bridge Controller (BRC) module designed for the Symphony Plus HR Series (Harmony Rack) distributed control system, which is the evolution of the legacy INFI 90 platform. It serves as the central processing unit for process control, executing complex control algorithms and managing multi-channel I/O subsystem communications.
