Q&A

Q: Does this kit include the TP830 baseplate? A: No, the PM861AK02 kit consists of the processors and synchronization cables; the TP830 baseplate required for mounting must be purchased separately.

Q: What is the main difference between PM861A and PM864A? A: The PM861A has 16MB of memory and a lower clock speed, making it suitable for standard applications, while the PM864A offers higher memory and performance for larger, more complex logic.

Q: Can I run this processor in a non-redundant (single) mode? A: Yes, the PM861A units within the kit can function as standalone processors, but the K02 kit is specifically packaged and priced for redundant applications.
