This module provides eight (8) sourcing outputs, organized into two isolated groups of four, making it suitable for demanding industrial applications that require driving high-wattage loads such as heavy-duty solenoids, actuators, and large indicators. The module is specifically engineered to handle higher current demands than standard digital output cards without requiring thermal derating.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Current Capacity:\u003c\/strong\u003e Delivers 2.0 Amps continuous current per point across the full operating temperature range (0 to 60 degC).\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIsolated Output Groups:\u003c\/strong\u003e Eight outputs configured in two isolated groups for flexible wiring and circuit protection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiagnostic Indicators:\u003c\/strong\u003e Integrated e-fuse LED indicators provide real-time status monitoring and rapid fault identification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Power Performance:\u003c\/strong\u003e Designed for 20.4–26.4V DC sourcing applications with minimal on-state voltage drop.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eApplications\u003c\/h3\u003e\n\u003cp\u003eThe 1746-OBP8 is ideal for control systems where standard I\/O modules lack the current capacity to drive inductive or high-draw resistive loads.
