This unit provides eight discrete sinking outputs, specifically designed to handle high-current requirements for field devices operating within the 10V to 50V DC range. By controlling the negative side of the load circuit, this module ensures efficient switching by connecting the load directly to the common rail during the energized state.\u003c\/p\u003e\u003ch3\u003eFeatures\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eEight isolated sinking output channels grouped together for efficient wiring.\u003c\/li\u003e\n\u003cli\u003eRapid switching performance 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 10-50V DC, supporting diverse industrial load requirements.\u003c\/li\u003e\n\u003cli\u003eIntegrated status indicators for local monitoring of output channel states.\u003c\/li\u003e\n\u003cli\u003eRobust SLC 500 backplane interface requiring 135 mA at 5V DC.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\u003ctable\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\u003eSeries\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage\u003c\/td\u003e\n\u003ctd\u003e10-50V DC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (5V)\u003c\/td\u003e\n\u003ctd\u003e135 mA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBackplane Current (24V)\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\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOff-Signal Delay\u003c\/td\u003e\n\u003ctd\u003e1.0 ms\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 60 degC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 degC\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 firmly seated into the chassis slot and secured using the top and bottom mounting screws.\u003c\/li\u003e\n\u003cli\u003eUse appropriate wire gauges for field connections and ensure all wiring is routed away from high-voltage AC lines to minimize electromagnetic interference.\u003c\/li\u003e\n\u003cli\u003eMaintain adequate ventilation within the enclosure to keep ambient temperatures within the specified 0 to 60 degC operating range.\u003c\/li\u003e\n\u003cli\u003eFollow standard ESD protection procedures when handling the module to prevent circuit board damage.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompliance and Certifications\u003c\/h3\u003e\u003cp\u003eThe 1746-OV8 is designed for compliance with global industrial standards, including UL, C-UL, CE, and C-Tick.
