Backplane Bus Communication Velocity & I/O Density Scaling
The IC695HSC304 links directly to the PACSystem RX3i backplane bus, transferring synchronized high-frequency counter accumulation data and discrete state evaluations back to the main processor. Utilizing a 40 MHz internal sampling rate alongside a 1.5 MHz maximum counting velocity across 4 independent channels, the module provides high I/O density scaling with 8 physical inputs and 7 physical outputs. Firmware flash compatibility ensures seamless dynamic parameter updates from the CPU during initialization and runtime operation.
Frequently Asked Questions
Q: What are the input voltage levels supported by the IC695HSC304 high-speed inputs?
A: The physical inputs support 5 VDC as well as 12 to 24 VDC nominal signal levels, with a maximum peak input voltage threshold of 35 VDC.
Q: What is the maximum output current capacity per channel and per module?
A: Each physical output channel supports up to 1.5 A, with a total cumulative output rating of 10.5 A across all outputs on the module.
Q: Which counting modes can be configured on the IC695HSC304 module?
A: The module's four independent counter channels can be software-configured for Type A, B, C, D, E, and Z operating modes.
Field Installation Guidelines
- Turn off power to the RX3i rack prior to installing or removing the IC695HSC304 module to prevent electrical damage to backplane pin connections.
- Ensure the module chassis is fully seated in its baseplate slot with top and bottom retaining clips locked securely in place.
- Wire high-speed input sensors using shielded twisted-pair cables, grounding cable shields at a single ground point to suppress electromagnetic noise.
- Separate field signal wiring and high-speed output lines from high-voltage AC circuits and variable frequency drive output conduits.
