The S series I/O modules are divided into four categories based on "signal type" and "functional characteristics". The core uses and typical models of each module are shown in the table below:
Module Category Core Usage Typical Model Example Key Features
The digital input (DI) module collects discrete signals from industrial sites (such as sensor and limit switch status), converts them into system recognizable digital signals SDI810 and SDI820, supports dry/wet contact input, has photoelectric isolation function, strong anti-interference ability, and some models support "event capture" (such as edge detection)
PR6426 is a non-contact 32mm eddy current sensor designed for critical turbomachinery applications, which can be used to measure radial and axial shaft displacement, including position, eccentricity, and motion. It is suitable for equipment including steam turbines, gas turbines, water turbines, compressors, pumps, and fans.
PACSystems RX3i I/O is a modular industrial grade input/output system launched by Emerson, designed specifically for process control, hybrid control, and discrete control scenarios. Its core advantages lie in high-performance data transmission, flexible scalability, and comprehensive diagnostic capabilities, which can adapt to automation needs from small and medium-sized equipment to large and complex production lines. At the same time, it provides a convenient legacy system upgrade path to protect users' existing investments.
Eaton XV-440-10TVB-1-20 (catalog number 139906) is a 10.4-inch human-machine interface (HMI-PLC) with integrated PLC functionality in the Eaton XV400 series, positioned as an "operation control+data interaction" terminal in industrial automation scenarios. It combines visual monitoring and logical control capabilities, and can directly communicate with on-site devices such as sensors, drivers, and PLCs to achieve equipment status display, parameter settings, fault alarms, and simple logical control. It is suitable for manufacturing production lines, mechanical equipment control, process automation, and other scenarios.
This product should pay attention to the * * "Non New Application Recommendation" * * label, which is more suitable for upgrading or replacing existing systems, rather than the preferred model for brand new projects.
