FAQ
FAQ
Q1: What is the maximum number of HART devices supported per SAI143-H53 module?
A1: Each channel can connect to one HART device, totaling 16 HART devices for all channels.
Q2: Can the SAI143-H53 be used in a dual-redundant configuration?
A2: Yes, dual redundancy is supported when an additional module with identical specifications is installed without option codes.
Q3: How does the module handle temperature variations?
A3: The module has a temperature drift of ±16 µA per 10 °C, ensuring stable measurement in typical operating conditions.
Q4: What is the input impedance during Power-ON?
A4: The input impedance ranges from 272.5 Ω (20 mA) to 362.5 Ω (4 mA) including the voltage drop of 0.45 V in the protection circuit.
Q5: Is intrinsic safety supported with Zener barriers?
A5: No, Zener barriers cannot be used; an isolation barrier is required for intrinsic safety systems.
Q6: What is the maximum permissible input current?
A6: The permissible input range is 0–25 mA, while the rated input is 4–20 mA.
Q7: How frequently does the module update its data?
A7: Data update occurs every 40 ms, providing near-real-time signal processing.
Q8: Can the transmitter power be turned off individually per channel?
A8: No, in 2-wire setting, the ON/OFF function applies to all 16 channels simultaneously.
