Product Features
YOKOGAWA ADM51-2 S4 provides 32 isolated digital input/output channels, supporting mixed dry and wet contact connections, and can be flexibly configured for input or output mode.
YOKOGAWA ADM51-2 S4 supports dual 24V DC power supply, ensuring that critical signals are not lost in the event of a power outage.
YOKOGAWA ADM51-2 S4 features built-in self-diagnostic functionality, continuously monitoring channel status, power voltage, and communication links, and supports rapid fault localization via LED indicators or upper-level software.
YOKOGAWA ADM51-2 S4 is compatible with industrial protocols such as HART and Profibus PA, enabling seamless integration with DCS systems like YOKOGAWA CENTUM CS/VP, and also supports third-party PLCs.
YOKOGAWA ADM51-2 S4 supports software-programmable channel logic configuration to accommodate different device interface requirements. It can be used in conjunction with YOKOGAWA signal conditioning cards, terminal boards, and other accessories to expand system functionality.
Product Using Principle
YOKOGAWA ADM51-2 S4 input channel detects the status of dry contacts or the voltage of wet contacts through an optocoupler, converting analog signals into digital values (0/1).
The digital signals are packaged into a specific protocol format by the internal processor and transmitted to the controller via the backplane bus.
When it receives instructions from the controller, the output channel drives external devices through solid-state relays or transistors, while simultaneously feeding back status signals to the controller.
