Additional Notes
- (*1) SAI143-H includes HART communication, available from release R1.02.00.
- (*2) Withstand voltage applies to specified configurations; signal cable interface adapter affects explosion protection options.
- (*3) Rated accuracy for SAI143-H extends to a broader input range (0.05 to 23 mA); dual-redundant terminal blocks enhance reliability.
- (*4) Prevention pin (/PRP) ensures correct module insertion.
- (*5) Module isolation supports 16 channels; high-density installation option (C) optimizes space.
- (*6) Voltage drop occurs in the internal input protection circuit during Power-ON.
- (*7) Transmitter power supply ON/OFF function is exclusive to 2-wire settings across all channels.
