Exceptional Processing Power
The PC0984685 features a 32-bit RISC processor that executes Boolean logic at blazing speed. It completes 1K instructions in just 0.15 ms, ensuring rapid scan cycles for time-critical applications. This performance allows complex mathematical operations and data handling without delaying the overall control loop. In addition, the processor supports floating-point calculations for advanced process control algorithms.
Extensive Memory Architecture
This CPU module provides 512 KB of battery-backed RAM for user programs and process data. The lithium battery retains this memory for up to six months, protecting valuable application code during power outages. An additional 256 KB of Flash EPROM stores the operating system and firmware permanently. Furthermore, the module includes 2,048 data registers and 512 timers or counters. These plentiful resources support sophisticated control strategies and extensive data logging.
Built-In I/O for Flexible Integration
The PC0984685 integrates 16 digital inputs and 12 digital outputs directly on the module. These onboard points handle simple monitoring and control tasks without requiring additional I/O modules. You can connect limit switches, push buttons, pilot lights, and small relays directly to the CPU. Consequently, this built-in functionality reduces overall system cost and saves rack space for other modules.
Versatile Communication Options
This processor module offers two RS-232 ports for flexible device connectivity. The first port serves as the primary programming interface for software uploads and debugging. The second port connects to HMIs, operator panels, or other serial devices. Both ports support adjustable baud rates up to 115.2 kbps. Therefore, the PC0984685 integrates seamlessly into existing communication infrastructures.
Rugged Design for Harsh Environments
The PC0984685 carries ATEX Zone 2 certification, allowing installation in potentially explosive atmospheres. It operates reliably across a 0 °C to 60 °C temperature range, suiting diverse factory conditions. Its compact dimensions and light weight simplify rack mounting and reduce mechanical stress. This robust construction ensures dependable operation in even the most challenging industrial settings.
