FAQ

Q: Can this module operate with field devices at different voltage levels?
A: It is designed for 24 VDC standard discrete signals. Signals outside the threshold range may not be reliably detected.

Q: What is the maximum pulse counting frequency?
A: The module supports discrete pulse counting up to 75 Hz.

Q: Is external power needed for the inputs?
A: No, field circuit power is not required; the module is powered through the DeltaV local bus.

Q: Are there similar modules with higher channel counts?
A: Emerson offers 16-channel and 32-channel discrete input modules in the VE4000S2 series for larger installations.
