| Weight | Approx. 0.34 kg with pressure clamp terminal block or MIL cable; approx. 0.39 kg with signal cable interface adapter |
| External connection | Pressure clamp terminal, MIL cable, or dedicated signal cable |
| PRM support | Available for SAI143-H |
HART Communication
The SAI143-H version supports HART communication. Yokogawa specifies HART Protocol Revision 5.7 and allows connection of HART 5, 6, and 7 devices.
Connection & Installation
Signal Cable Interface
The “6” suffix specifies the signal cable interface adapter without explosion protection.
/PRP Prevention Pin
/PRP provides the prevention pin used to help prevent insertion of the wrong I/O module type.
Matching Signal Cable
The corresponding dedicated signal cable uses the /SAI143 option with a module carrying the /PRP prevention-pin option.
Installation Interface
The module uses its specified signal cable, terminal, or cable interface configuration for connection within the ProSafe-RS I/O arrangement.
Dual-Redundant Configuration
Yokogawa states that SAI143 can be used in a dual-redundant configuration. An additional module with the same specifications but without option codes is required.
Dual-redundant pressure clamp terminal block for SAI143 configurations.
System Compatibility
ProSafe-RS Architecture
SAI143 is documented for mounting on ProSafe-RS safety control units and safety node units within the specified module-mounting configuration.
Replacement Matching
Replacement selection should match the complete model suffix and option configuration rather than relying on the base SAI143 designation alone.
