Technical FAQ
Can the module handle both active and passive transmitters?
Yes. Depending on terminal wiring, it supports 2-wire (powered by the module) and 4-wire (externally powered) transmitters.
What does the /A4D00 option code indicate?
It specifies a dual-redundant terminal interface with pressure clamp terminals for easy pairing of two modules in high-availability configurations.
Is the module compatible with standard CENTUM VP systems?
The SAI143-H53/A4D00 is certified specifically for ProSafe-RS. Use in CENTUM VP systems requires verification against safety and compatibility requirements.
