It accepts 24 VDC contact input circuits and transfers discrete ON\/OFF status information to the system. This configuration includes a dual-redundant pressure clamp terminal block without surge absorbers, providing a defined field wiring arrangement for digital signal acquisition.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eDigital Input Function\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe SDV144 receives signals from external voltage-free contacts and converts their electrical states into digital input information for system processing. Its 16-channel architecture allows multiple field contact signals to be monitored through one module.\u003c\/p\u003e\n\u003cp\u003eThe module uses module-level isolation between the input circuits and the system side. This isolation separates field input signals from the system electronics and is specified with a 2 kV AC withstand voltage for one minute.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eInput Signal Characteristics\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe input circuit is designed for 24 VDC external contact distribution. The specified input current is 6 mA +\/-20% at 24 VDC, while the ON and OFF resistance thresholds define the electrical conditions used to distinguish contact states.\u003c\/p\u003e\n\u003cp\u003eThe maximum instantaneous permissible input voltage is 30 VDC. The specified maximum response time is 40 ms, which should be considered when evaluating digital event acquisition and application response requirements.\u003c\/p\u003e\n\u003ch3\u003e\u003cstrong\u003eTerminal Block Configuration\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eThe \/B4D00 option identifies a \u003cstrong\u003edual-redundant pressure clamp terminal block without surge absorbers\u003c\/strong\u003e, designated STB4D-00. This is a terminal connection configuration; it does not, by itself, establish that one SDV144 module provides complete system-level I\/O redundancy.\u003c\/p\u003e\n\u003cp\u003eFor a dual-redundant module arrangement, Yokogawa's ordering instructions specify an additional module with the same specification but without the terminal block option code.
