This module features eight (8) sinking outputs, providing a reliable interface for controlling 24V to 48V DC field devices. As a sinking output module, it is engineered to control the negative side of the load circuit, effectively connecting the load to the DC common when the output is energized.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEight (8) sinking output channels grouped together.\u003c\/li\u003e\n\u003cli\u003eDesigned for high-current applications within the SLC 500 platform.\u003c\/li\u003e\n\u003cli\u003eRapid response times with an ON-signal delay of 0.1 ms and an OFF-signal delay of 1.0 ms.\u003c\/li\u003e\n\u003cli\u003eWide operating voltage range of 10V to 50V DC.\u003c\/li\u003e\n\u003cli\u003eRobust design suitable for demanding industrial environments.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eApplications\u003c\/h3\u003e\u003cp\u003eThe 1746-OV8 is ideal for high-speed switching tasks in industrial automation, including solenoid control, relay actuation, and driving DC-powered indicators or actuators within an SLC 500 control architecture.\u003c\/p\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable border=\"1\"\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen-Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003eSLC 500\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eDigital DC Output (Sinking)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e8 (1 Group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Range\u003c\/td\u003e\n\u003ctd\u003e10–50V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V DC)\u003c\/td\u003e\n\u003ctd\u003e135 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24V DC)\u003c\/td\u003e\n\u003ctd\u003e0 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOn-Signal Delay\u003c\/td\u003e\n\u003ctd\u003e0.1 ms (max resistive load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOff-Signal Delay\u003c\/td\u003e\n\u003ctd\u003e1.0 ms (max resistive load)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC (32 to 140 degF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 degC (-40 to 185 degF)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelative Humidity\u003c\/td\u003e\n\u003ctd\u003e5% to 95% (non-condensing)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\u003ch3\u003eInstallation Guidelines\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEnsure the SLC 500 chassis power is disconnected before installing or removing the module to prevent electrical damage.\u003c\/li\u003e\n\u003cli\u003eVerify that the module is fully seated in the chassis slot and secured with the top and bottom retaining screws.\u003c\/li\u003e\n\u003cli\u003eUse appropriate shielded cabling for field wiring to minimize electromagnetic interference (EMI).\u003c\/li\u003e\n\u003cli\u003eEnsure that the load current does not exceed the specified limits for the module channels.\u003c\/li\u003e\n\u003cli\u003eMaintain proper ventilation within the control cabinet to keep the ambient temperature within the 0 to 60 degC range.\u003c\/li\u003e\n\u003cli\u003eHandle the module using proper ESD (Electrostatic Discharge) prevention techniques.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\u003cp\u003eThe 1746-OV8 is certified for use in hazardous locations, meeting Class I, Division 2 standards for Groups A, B, C, and D.
