It integrates 20 digital input channels for field signal acquisition alongside 12 fully isolated digital relay outputs, enabling controllers to monitor process conditions and switch external loads.\u003c\/p\u003e\n\u003ch3\u003eI\/O Configuration and Relay Switching\u003c\/h3\u003e\n\u003cp\u003eThe module provides high-density discrete interfacing within a single unit. Its 12 relay output channels support a switching voltage range of 24 to 240 V AC\/DC to drive auxiliary relays, contactors, lamps, or solenoid valves. Standard versions recommend a minimum load of 2.5 VA (100 mA at 24 V DC), while the DSDX452L variant provides low-voltage relay contacts designed for smaller signal-level loads (maximum 200 mA, minimum 5 mA or 0.05 VA).\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\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\u003eDSDX452\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eABB\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Series\u003c\/td\u003e\n\u003ctd\u003eS400 I\/O \/ Advant OCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Type\u003c\/td\u003e\n\u003ctd\u003eMixed Digital I\/O Modules\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Inputs\u003c\/td\u003e\n\u003ctd\u003e20 channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDigital Outputs\u003c\/td\u003e\n\u003ctd\u003e12 relay channels\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Switching Range\u003c\/td\u003e\n\u003ctd\u003e24 to 240 V AC\/DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStandard Output Load\u003c\/td\u003e\n\u003ctd\u003e2.5 VA recommended (100 mA minimum at 24 V DC)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLow-Voltage Variant\u003c\/td\u003e\n\u003ctd\u003eDSDX452L (max 200 mA; min 5 mA or 0.05 VA)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSystem Compatibility\u003c\/td\u003e\n\u003ctd\u003eABB S400 I\/O systems and Advant OCS\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: How many input and output channels does the DSDX452 provide?
