Common FAQ
Is the SCP401-11 compatible with the newer CENTUM VP system?TheSCP401-11was primarily designed for the CS 3000 series. While some legacy integration is possible, newer systems typically utilize the SCP451 or CP461 modules. It is recommended to verify your specific controller base unit compatibility.
What does the "Pair-and-Spare" feature provide?In a redundant setup, twoSCP401-11modules run in parallel. If a hardware fault is detected in the active unit, the system switches to the standby module instantaneously without any "bump" in the process signal or control logic.
