FAQ
Frequently Asked Questions (FAQ)
Q1: What type of field devices are compatible with the VE4001S2T2B4?
A1: This module is designed for dry contact devices operating at 24V DC, including mechanical switches and many NAMUR sensors.
Q2: Does the VE4001S2T2B4 support redundancy?
A2: No, VE4001S2T2B4 is a simplex card. For redundant applications, use VE4031S2T2B4 with the appropriate terminal block.
Q3: What is the difference between the VE4001S2T2B4 and VE4001S2T2B1?
A3: VE4001S2T2B4 is a 32-channel card using a 32-screw terminal block. VE4001S2T2B1 is an 8-channel card with different wiring and form factor.
Q4: What is the wetting voltage, and why is it important?
A4: The wetting voltage is 24V DC, which ensures reliable activation of contact devices by preventing oxidation buildup on the contact surfaces.
Q5: Can the VE4001S2T2B4 detect pulses from field devices?
A5: Yes, it supports pulse count mode for input frequencies below 75 Hz, suitable for applications like flow metering or event logging.
Q6: What diagnostics does the module support?
A6: It includes internal error indication and channel isolation. Combined with the DeltaV diagnostics explorer, it enables real-time health monitoring.
Q7: How should I wire the terminal block?
A7: VE4001S2T2B4 uses a 32-screw terminal block with a shared common return. Pre-wiring is possible before the card installation.
Q8: Is this card suitable for hazardous areas?
A8: Yes, it meets FM, ATEX, and IECEx standards for Class I, Div 2 (Zone 2) installations. Always follow proper installation practices in such areas.
