FAQ

What is the maximum number of input channels for SAI143-H53 under high ambient temperature?
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.

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

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

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

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

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

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

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