Q&A Section

• Q: Does the PM891K01 kit include the baseplate?

  • A: Yes, the “K01” suffix typically indicates a kit that includes the processor unit and the necessary TP830 baseplate for connectivity.

• Q: How does the redundancy feature work?

  • A: Two PM891 units operate in parallel; if the primary unit fails, the backup takes over control bumplessly within milliseconds.

• Q: Can this processor handle SIL3 safety applications?

  • A: While the PM891 is a high-performance controller, specific “High Integrity” (HI) versions are required for certified SIL3 safety functions.
