Connect a stable 24V DC field power supply. For \u003cb\u003esourcing outputs\u003c\/b\u003e, wire your load (e.g., a solenoid valve) between the output terminal and the DC common (-) line. The module acts as a switch to the positive voltage when active. Ensure the total current for all outputs sharing a single common terminal does not exceed \u003cb\u003e4.0 Amps\u003c\/b\u003e. For inductive loads like relay coils, install a flyback diode across the load to protect the output circuit.\u003c\/p\u003e\n\u003ch3\u003ePackage \u0026amp; Warranty\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eWhat's Included:\u003c\/b\u003e 1 x Allen-Bradley 1790D-T0B16 Sourcing Output Module with terminal block.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eOur Guarantee:\u003c\/b\u003e This product is protected by a full \u003cb\u003e12-month warranty\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFast Global Shipping\u003c\/h3\u003e\n\u003cp\u003eWe deliver quickly using reliable carriers: \u003cb\u003eFedEx, UPS, and DHL\u003c\/b\u003e.\u003c\/p\u003e\n\u003ch3\u003eFrequently Asked Questions (FAQ)\u003c\/h3\u003e\n\u003cp\u003e\u003cb\u003eWhat is the difference between this and the 1790-T0B16X model?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eBoth are 16-point sourcing modules with terminal blocks. The \u003cb\u003e1790D-T0B16\u003c\/b\u003e is a \"Base\" module that can also support the connection of expansion I\/O modules. The \"X\" variant is typically a standalone unit.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eCan I connect this output directly to a PLC input?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eYes. A sourcing output is ideal for driving a sinking PLC input. Connect the output to the PLC input, and connect the PLC input's common to the DC negative (-) of the shared power supply.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eWhat happens if an output short-circuits?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eThe module includes electronic protection that typically limits the short-circuit current and may shut down the affected channel to prevent damage. Always use external fuses for additional safety.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eHow do I set the DeviceNet node address?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eUse the rotary switches on the module's side to set the \u003cb\u003eNode Address (MAC ID from 0 to 63)\u003c\/b\u003e and the \u003cb\u003eCommunication Baud Rate (125K, 250K, or 500K)\u003c\/b\u003e to match your network.\u003c\/p\u003e\n\u003cp\u003e\u003cb\u003eIs it suitable for high-speed switching applications?\u003c\/b\u003e\u003c\/p\u003e\n\u003cp\u003eWith a 0.5 ms response time, it is suitable for many industrial on\/off applications. For very high-speed pulse trains (kHz range), a dedicated fast output or pulse module would be more appropriate.\u003c\/p\u003e\n\u003cp\u003e© 2025 Ubest Automation Limited.
