Product Features
YOKOGAWA SDV144-S63 has 16-channel digital inputs with module-level isolation design to avoid inter-channel signal interference.
YOKOGAWA SDV144-S63 can be configured in dual redundancy mode to enhance system reliability and is suitable for high-security scenarios.
YOKOGAWA SDV144-S63 complies with ISA standard G3 and has an operating temperature range of -20 to 70°C, adapting to high-temperature industrial environments.
YOKOGAWA SDV144-S63 can be equipped with a signal cable interface adapter (suffix code “6”) to support the connection of dedicated signal cables (e.g. AKB331) to simplify field wiring.
YOKOGAWA SDV144-S63 can be optionally coded with “/PRP” option to avoid module mis-insertion through the anti-mis-insertion mechanism of the signal cable (signal cable with “/SDV144” option is required).
YOKOGAWA SDV144-S63 supports field wiring fault detection (with SCB100/SCB110 diagnostic components):
SCB100: for detecting open-circuit faults when the signal is normally “OFF”.
SCB110: for detecting short-circuit faults when the signal is normally “ON”.
Product Using Principle
YOKOGAWA SDV144-S63 can convert the voltage-free contact signals of field equipment into digital signals that can be processed by the safety control unit, and the specific working logic is as follows:
Signal Reception: the contact action of field equipment (ON/OFF) changes the input circuit resistance (ON ≤ 1kΩ, OFF ≥ 100kΩ), the module recognizes the signal state by detecting the resistance change.
Signal Conversion: the resistance change is converted into digital quantity (0/1), which is processed by the internal circuit and then transmitted to the safety control unit through the signal cable.
Redundancy: In a dual redundancy configuration, the two SDV144-S63 modules collect signals synchronously and the safety control unit compares the two signals to ensure that no data is lost in the event of a single module failure.
Fault Diagnosis: If it is necessary to detect open or short circuit of wiring, it is necessary to connect SCB100 (detecting open circuit when normal OFF) or SCB110 (detecting short circuit when normal ON) in series between the field equipment and the module, and the diagnostic results are uploaded together with the signal.
