Built for Clear Status Acquisition

The Yokogawa SDV144-S5C/B4S10 is a digital input module designed to bring discrete field status into a compatible control system. With 16 input channels and a 24 V DC signal class, it suits installations that need a defined interface for equipment states, contact signals and interlock feedback.

The specified /B4S10 option identifies a pressure-clamp terminal block with a surge absorber. This terminal arrangement is an important ordering detail: it affects how the field wiring is terminated and should be checked against the cabinet's existing terminal and cable design before replacement.

The S5C configuration also includes the relevant product suffix selections. Confirm the full code on the installed unit and purchase requirement rather than matching the base model alone.

Field Contacts

Check whether the existing field circuits use the expected 24 V DC digital input class and verify the wiring diagram before reconnecting the replacement.

STB4S-10

The `/B4S10` option specifies a pressure-clamp terminal block with surge absorber. Do not assume a different terminal option is a direct mechanical or wiring substitute.

I/O Compatibility

Confirm the host system, node configuration, slot assignment, field cable and engineering configuration. Matching the model family alone is not enough.
