Yokogawa SAI143-H53/A4S00 16-Channel Analog Input Module

FAQ

Q1: What is the maximum number of input channels for SAI143-H53 under high ambient temperature?
A1: When ambient temperature exceeds 60 °C, the number of usable input channels may be restricted. Refer to ProSafe-RS Outline of I/O Modules (GS 32P06K60-01EN) for detailed limitations.

Q2: Can Zener barriers be connected directly to this module?
A2: No. Zener barriers cannot be used. An isolation barrier is required for intrinsic safety applications.

Q3: What is the response time for HART communication?
A3: Maximum response time is 28 characters (256.7 ms). No-response timers are 305 ms for primary and 380 ms for secondary channels.

Q4: Is the module suitable for dual-redundant configuration?
A4: Yes, SAI143-H53 can be configured as dual redundant. An additional module with identical specifications is required.

Q5: How is transmitter power supplied to 2-wire devices?
A5: The module provides a 16.15–26.4 V transmitter power supply. Power ON/OFF control is available to reset alarm states.

Q6: What is the rated accuracy for low current signals (<0.05 mA)?
A6: For style code S3 or later, rated accuracy is ±32 µA below 0.05 mA. Above 0.05 mA, accuracy is ±16 µA.

Q7: Which types of external connections are supported?
A7: Supported connections include pressure clamp terminal blocks and dedicated signal cables. MIL cable connectors are also compatible.

Q8: Can this module be used in high-density installations?
A8: Yes, suffix code C supports high-density installations for SAI143-H modules, compliant with ISA Standard G3
