Schneider Electric PC-E984-785 Modicon Compact Controller
Product Introduction
The PC-E984-785 belongs to Schneider Electric’s trusted Modicon product line. This compact controller handles mid-to-large automation tasks with ease. Its scalable memory and I/O capacities make it suitable for various industries, from manufacturing to infrastructure. Additionally, its fast scan time supports real-time control requirements. For system integrators and maintenance engineers, this model offers a balance of performance and simplicity. The PC-E984-785 also simplifies network integration through its built-in Modbus and Modbus+ ports.
Key Technical Specifications
This controller provides user memory configurable at either 32k or 48k, depending on your application complexity. Its register I/O capacity reaches a maximum of 1088, while discrete I/O expands up to 16384 points. Data memory options include 64k or 32k, giving flexibility for storing logic, timers, and operational parameters. Furthermore, the scan time is rated at just 1 millisecond per kilobyte, which ensures prompt response to field device changes. Communication ports consist of two standard Modbus interfaces and one Modbus+ port, enabling seamless integration with HMIs, drives, and remote I/O stations.
Mechanical and Environmental Parameters
This unit weighs approximately 2.27 kg and fits into standard Modicon backplanes. It operates within a temperature range of 0°C to 60°C and supports humidity levels from 10% to 95% non-condensing. The enclosure design protects against dust and minor vibrations, making it suitable for factory floor installations. Additionally, the controller draws low power, reducing heat dissipation within the cabinet.
