It provides module-level isolation and operates with a 24 V DC external input supply. This configuration includes an STB4S-00 pressure clamp terminal block without a surge absorber and supports ISA Standard G3 environmental conditions.\u003c\/p\u003e\n\u003ch3\u003eFunctional Description\u003c\/h3\u003e\n\u003cp\u003eThe SDV144 receives discrete contact signals from external devices, such as limit switches and relay contacts, and transfers their ON\/OFF status to the control system. Its 16 input channels allow multiple field contact states to be monitored through one module.\u003c\/p\u003e\n\u003cp\u003eThe input circuit distinguishes contact states by resistance: ON is recognized at 1 kOhm maximum, while OFF is recognized at 100 kOhm minimum. The specified input current is 6 mA +\/-20% with a 24 V DC external supply and a 0 Ohm input resistance.\u003c\/p\u003e\n\u003ch3\u003eTerminal Block Configuration\u003c\/h3\u003e\n\u003cp\u003eThe \/B4S00 option specifies a pressure clamp terminal block for digital input connections. Its associated terminal block model is STB4S-00, supplied without a surge absorber. This is a single terminal-block configuration, not the dual-redundant STB4D arrangement.\u003c\/p\u003e\n\u003cp\u003eThe pressure clamp connection provides the field wiring interface for the module. When checking a replacement, verify the complete suffix and terminal-block option rather than identifying the unit by the SDV144 base model alone.\u003c\/p\u003e\n\u003ch3\u003eInput Signal Characteristics\u003c\/h3\u003e\n\u003cp\u003eThe module accepts no-voltage contact signals rather than treating the input as a general-purpose analog voltage channel. The 24 V DC external supply provides the input circuit operating voltage, while the contact resistance determines the interpreted state.\u003c\/p\u003e\n\u003cp\u003eThe maximum input response time is 40 ms. This specification should be considered when checking signal timing requirements for discrete status monitoring and interlock inputs.\u003c\/p\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cfigure\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003eParameter\u003c\/th\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eSDV144\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFull Model\u003c\/td\u003e\n\u003ctd\u003eSDV144-S53\/B4S00\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eYokogawa\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eDigital Input Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem\u003c\/td\u003e\n\u003ctd\u003eProSafe-RS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n\u003ctd\u003e16 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Signal\u003c\/td\u003e\n\u003ctd\u003eNo-voltage contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eON Input Resistance\u003c\/td\u003e\n\u003ctd\u003e1 kOhm maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOFF Input Resistance\u003c\/td\u003e\n\u003ctd\u003e100 kOhm minimum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Current\u003c\/td\u003e\n\u003ctd\u003e6 mA +\/-20%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eContact Rating\u003c\/td\u003e\n\u003ctd\u003e24 V DC +\/-5%, 10 mA or greater\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Power Supply\u003c\/td\u003e\n\u003ctd\u003e24 V DC +\/-5%\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExternal Supply Current Capacity\u003c\/td\u003e\n\u003ctd\u003e200 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaximum Instantaneous Input Voltage\u003c\/td\u003e\n\u003ctd\u003e30.0 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Response Time\u003c\/td\u003e\n\u003ctd\u003e40 ms maximum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003eModule isolation\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWithstand Voltage\u003c\/td\u003e\n\u003ctd\u003e2 kV AC for 1 minute\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e290 mA maximum at 5 V DC; 140 mA maximum at 24 V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTerminal Block\u003c\/td\u003e\n\u003ctd\u003eSTB4S-00 pressure clamp terminal\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSurge Absorber\u003c\/td\u003e\n\u003ctd\u003eNot included\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e-20 to 70 deg C\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnvironmental Standard\u003c\/td\u003e\n\u003ctd\u003eISA Standard G3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e130 x 32.8 x 107.5 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.36 kg\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eSpecifications are based on Yokogawa General Specifications GS 32Q06K40-31E.
