Description
Yokogawa SDV144-S13/B4D00 Digital Input Module
Configured for 16-channel isolated 24 VDC contact signal acquisition in CENTUM DCS digital I/O subsystem, the Yokogawa SDV144-S13/B4D00 (SDV144 Digital Input Module) provides direct physical/electrical execution. The module performs discrete signal sampling from no-voltage contact inputs and transfers state information to the system backplane with galvanically isolated channel architecture.
SuffixBreakdown&ModelMatrix
No validated functional decomposition is defined by Yokogawa for the SDV144-S13/B4D00 ordering code beyond manufacturing and revision identifiers. All functional behavior is inherited from the SDV144 hardware platform.

Yokogawa Channel Isolation And Field Signal Handling
The SDV144 platform implements channel-to-channel electrical isolation for discrete input acquisition, reducing cross-channel interference during 24 VDC contact state transitions. Input detection is performed through opto-isolated conditioning stages aligned with Yokogawa CENTUM DCS backplane scanning cycles. The module is designed to maintain defined ON/OFF resistance thresholds for dry contact interfaces under industrial noise conditions, with input validation performed within the specified response time window.
FrequentlyAskedQuestions
Q: Can the SDV144-S13/B4D00 be hot-swapped during system operation?
A: Hot-swap capability depends on the base unit and carrier hardware. The module itself does not define standalone hot-swap behavior.
Q: What is the backplane current load requirement for this module?
A: 5 VDC backplane consumption is specified as 290 mA maximum under full channel operation.
Q: What isolation level is provided between input signals and system logic?
A: The module provides 2 kV AC dielectric withstand voltage between input circuitry and system side for 1 minute.
FieldInstallationGuidelines
Ensure power isolation before insertion or removal from the I/O base unit. Maintain correct polarity and rating compliance for 24 VDC contact inputs. Field wiring shall use shielded twisted conductors where noise coupling is present, with shield termination at a single-point ground reference.
Avoid routing input signal cables parallel to high-voltage switching conductors. Maintain separation distance in accordance with site EMC design rules. Verify that input devices comply with dry contact or equivalent no-voltage switching characteristics before termination.
Backplane connectors must be fully seated to ensure stable signal acquisition and isolation integrity.
