FAQ
FAQ
-
Q1: What is the maximum number of input channels supported by SAI143-H33 S2?
A1: The module supports 16 input channels with module isolation. Channel usage may be restricted at ambient temperatures above 60°C. -
Q2: Can the SAI143-H33 S2 module be used in a dual-redundant configuration?
A2: Yes, dual redundancy is supported by ordering an additional module with the same specifications. -
Q3: What is the input range accuracy for low-level signals below 0.05 mA?
A3: For Style code S2, rated accuracy is ±16 µA for the input range 0.05 to 23 mA. Below 0.05 mA, the accuracy may vary. -
Q4: What HART devices are supported per channel?
A4: One HART device can be connected per channel. Each channel has a dedicated power supply function. -
Q5: How does the module handle transmitter power supply control?
A5: The ON/OFF function is available in 2-wire settings for all 16 channels simultaneously, enabling reset of alarm states in connected devices. -
Q6: What are the conditions for safe voltage withstanding?
A6: The module can withstand 1.5 kV AC between input signal and system for 1 minute, or 500 V AC when using a dedicated signal cable. -
Q7: What is the data update frequency of the SAI143-H33 S2?
A7: The module updates analog input data every 40 ms. -
Q8: What is the maximum permissible input current for the module?
A8: The module allows an input current range from 0 to 25 mA, exceeding the rated range of 4 to 20 mA.
