FAQ
Frequently Asked Questions
Q1: What input signal does the SAI143-H53 support?
A1: It supports standard 4 to 20 mA current input, with a permissible range of 0 to 25 mA.
Q2: Is HART communication supported by this module?
A2: Yes, SAI143-H53 supports HART protocol revision 5.7 and can communicate with one HART device per channel.
Q3: What is the rated accuracy of the input?
A3: The rated accuracy is ±16 µA within the 0.05 to 23 mA input range.
Q4: Are the input channels isolated from each other?
A4: The module provides overall isolation, but channels share a common ground (not isolated from each other).
Q5: How does the transmitter power supply function?
A5: Each channel provides a minimum of 16.15 V at 20 mA with a maximum output current limit of 25 mA.
Q6: What connection methods are available for external wiring?
A6: The module supports pressure clamp terminals, MIL cables, or dedicated signal cables.
Q7: What is the data update frequency?
A7: The module updates data every 40 milliseconds, suitable for medium-speed analog signal acquisition.
Q8: Is additional configuration needed for redundancy?
A8: Yes, for dual-redundant configuration, an identical module should be installed without selecting conflicting option codes.
