The GE Fanuc IC695HSC308, also cataloged as the IC695HSC308 High-speed counter module, operates as a dedicated hardware component for high-speed counting, totalizing, and motion control within PACSystems RX3i platforms. The module interfaces directly with rapid-switching field sensors up to a frequency of 1.5 MHz, processing pulse inputs and driving local discrete outputs without requiring central processing unit intervention.

The IC697/IC695 internal logic structure interfaces via the universal backplane to achieve optimal communication velocity data transfers without requiring additional backplane bus communication velocity licences. Designed to manage dynamic I/O density scaling profiles, the hardware features configurable I/O interrupts that bypass typical bus latencies. The internal flash memory is completely upgradable via programming tools, ensuring long-term firmware flash compatibility with updated CPU modules while sustaining automated module fault reporting.
Q: Does the IC695HSC308 support removal and replacement operations while the backplane is energized?
A: Yes. The module fully supports Removal and Insertion Under Power (RIUP) and includes diagnostic detection circuits that monitor the connection status of the external terminal block assembly.
Q: What is the switching response delay of the local discrete output channels?
A: At a full 1.5 A load, the hardware turn-on time delay (off to on) is 125 microseconds. The turn-off time delay (on to off) is 85 microseconds under identical electrical load conditions.
Q: How many independent setpoints can a single counter channel govern?
A: Each counter on the module can control up to 4 distinct setpoints. These setpoints feature user-defined turn-on and turn-off threshold values mapped directly to the local physical outputs.
