Frequently Asked Questions (FAQ)
- What makes this a “redundant” I/O system?
The VE4035S2B1 card works with dual termination blocks. This setup allows for backup if one path fails, ensuring continuous operation. - Can I use only one termination block to save cost?
For true redundancy, you need both KJ3221X1-BA1 and KJ3221X1-EA1. Using only one block removes the system’s backup capability. - What type of cable should I use for field wiring?
Use standard shielded twisted-pair cable. This helps reduce electrical noise for accurate 4-20mA signal transmission. - How do I know if my power supply is adequate?
Your 24V DC supply must deliver at least 300mA for the field circuits. Also ensure it can power the LocalBus (12V, 150mA max). - Is this card suitable for safety instrumented systems (SIS)?
While robust, you must check specific system certifications. This module is for general high-reliability control, not dedicated SIS use.
