FAQ
Is the S2 version backward compatible with earlier SAI143 modules?
Yes, the S2 revision typically maintains compatibility with standard CENTUM VP backplanes while offering improved reliability and diagnostics. System software compatibility should still be verified.
Does the module supply loop power to transmitters?
No. Field transmitters usually require external 24 V DC loop power, typically provided by the terminal board or cabinet power distribution.
