Engineering Advantages

Extensive Non-Volatile Storage: The 256 kB RETAIN memory safeguards critical process variables during power interruptions. This hardware-level protection prevents data loss, ensuring the system resumes complex coordinated movements without requiring manual re-calibration.
High-Speed Counting Capability: Two integrated high-speed counter channels allow the CPU to process rapid pulse signals directly. This eliminates the need for external counting modules when interfacing with high-frequency encoders or flow meters, reducing overall system cost and complexity.
Enhanced Signal Integrity: Optocoupler signal coupling isolates the 24 digital input channels. This electrical separation between groups prevents ground loops and protects the internal CPU logic from high-voltage transients common in heavy industrial environments.
Configurable Input Response: The module supports adjustable signal delays, allowing engineers to reduce input filtering down to 1 ms. This high-speed response capability enables the CPU to detect ultra-fast state changes in rapid manufacturing and high-duty cycle applications.

FAQs

Q: Can the 07KT98C replace older AC31 basic units with less memory?

A: Yes. The 07KT98C offers 1MB of program memory, which typically exceeds the capacity of earlier AC31 models. It provides a direct upgrade path, assuming the system bus configuration and physical dimensions (280mm width) fit your existing rack space.

Q: Does this module require a battery for the RETAIN memory?

A: While the 07KT98C utilizes non-volatile architecture for long-term storage, a battery typically maintains the real-time clock and specific data registers during extended power-down periods. Check your system manual for battery replacement intervals to ensure uninterrupted operation.

Q: What is the benefit of the three isolated input groups?

A: Grouping the 24 digital inputs into three isolated sets of eight allows you to mix different signal sources or ground potentials within the same module. This prevents a localized fault in one field wiring group from damaging the entire CPU input bank.

Q: How do I configure the high-speed counter channels?

A: You access and configure the integrated counters via the AC31 programming environment. By mapping channels E 62,00 and 62,01 to specific internal registers, the CPU can execute logic based on real-time frequency or position data from the field.
