Designed for distributed I\/O architectures via communication adapters, this module features eight (8) discrete sinking input channels operating at a nominal voltage of 24VDC (10–28.8VDC input range). Weighing approximately 31.8 g (1.12 oz) with dimensions of 56 x 12 x 75.5 mm, it requires a 1734-TB or 1734-TBS terminal base assembly, draws 75 mA of POINTBus current at 5V DC, dissipates 1.6 Watts, and operates reliably across surrounding air temperatures from -21 °C to 55 °C.\u003c\/p\u003e\n\n\u003ch2\u003ePart Number Breakdown\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003e1734:\u003c\/strong\u003e Allen-Bradley POINT I\/O Modular Distributed I\/O Platform Series\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e-I:\u003c\/strong\u003e Digital Input Module Hardware Classification\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eB:\u003c\/strong\u003e Sinking Input Circuit Type Designation\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003e8:\u003c\/strong\u003e Eight (8) Discrete Input Channels Configuration\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications Table\u003c\/h2\u003e\n\u003ctable style=\"width: 100%;
