FAQ
FAQ
Q1: Does this module support redundant operation?
A1: Yes, it is designed for redundant analog input applications with paired backup modules.
Q2: What type of analog signal does it support?
A2: It supports 4–20 mA current input for industrial process measurement.
Q3: Are the input channels isolated?
A3: Yes, each channel is isolated from the system to minimize interference.
Q4: Is hot-swapping supported?
A4: Yes, but must follow DeltaV maintenance procedures.
Q5: What devices can be connected to this card?
A5: It can connect pressure transmitters, temperature transmitters, level gauges, flow transmitters, and other 4–20 mA instruments.
Q6: Is measurement accuracy affected by the power supply?
A6: Very minimally, thanks to isolation design, but stable system power is still recommended.
Q7: Will a single channel fault affect system operation?
A7: No, in redundant mode the system automatically switches to the healthy module.
Q8: Can this module replace KJ3221 or other AI cards?
A8: Not directly; replacement depends on channel count and system version compatibility.
