Real-Time Clock & Interrupt Module (RCIM III)
What is the Real-Time Clock & Interrupt Module (RCIM III)?
Concurrent’s Real-Time Clock & Interrupt Module (RCIM III) is a multifunction card designed for time-critical applications on Concurrent iHawk multiprocessing systems. The RCIM provides key functionality for single system as well as multiple system applications. Ideally suited for simulation, data acquisition and industrial
control solutions, the RCIM includes a synchronized clock, eight programmable realtime clocks, and twelve input and output external interrupt lines. The RCIM mounts in a standard iHawk PCIe or PCI slot and is fully supported by Concurrent’s RedHawk Linux real-time operating system.
