It features built-in DeviceNet network connectivity and removable screw-terminal blocks for field signal wiring. Operating as a standalone node or expanded system, the unit accepts sinking or sourcing 24 VDC input signals to interface field sensors directly with DeviceNet control networks.\u003c\/p\u003e\n\u003ch3\u003eUniversal Sinking\/Sourcing Digital Inputs\u003c\/h3\u003e\n\u003cp\u003eThe 16 digital input points are organized into two groups of eight channels. Each group features a dedicated common pin (COM 0 for inputs 0–7 and COM 1 for inputs 8–15), allowing independent configuration for either sinking or sourcing wiring topologies. Wiring COM 0 or COM 1 to field 24 VDC (+) configures sourcing inputs, while connecting to field power ground (-) configures sinking inputs.\u003c\/p\u003e\n\u003ch3\u003eDeviceNet Communication and Network Addressing\u003c\/h3\u003e\n\u003cp\u003eIntegrated directly into the base block, the DeviceNet port eliminates the need for separate communication adapters. Network node addresses (0 to 63) are set via hardware rotary switches or configured remotely through RSNetWorx for DeviceNet software. The module supports automatic baud rate detection for standard DeviceNet communication speeds of 125 kbps, 250 kbps, and 500 kbps.\u003c\/p\u003e\n\u003ch3\u003eExpandability and Mechanical Installation\u003c\/h3\u003e\n\u003cp\u003eDesigned for space-restricted enclosures, the open-style block mounts on standard DIN rails or directly onto panel surfaces. Terminal screw connections simplify field wiring and maintenance. The base block can power and communicate with CompactBlock LDX expansion I\/O blocks using an integral expansion bus connector, enabling local I\/O capacity expansion at a single network node.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1790D-T16BV0\u003c\/td\u003e\n\u003c\/tr\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 Family\u003c\/td\u003e\n\u003ctd\u003eCompactBlock LDX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003eDeviceNet Digital Input Base Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Inputs\u003c\/td\u003e\n\u003ctd\u003e16 universal DC inputs\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eInput Logic\u003c\/td\u003e\n\u003ctd\u003eSinking or Sourcing (selectable by channel group)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Voltage\u003c\/td\u003e\n\u003ctd\u003e24 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Voltage Range\u003c\/td\u003e\n\u003ctd\u003e9.6 to 28.8 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNetwork Interface\u003c\/td\u003e\n\u003ctd\u003eDeviceNet (built-in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Rates\u003c\/td\u003e\n\u003ctd\u003e125 kbps, 250 kbps, 500 kbps (Autobaud)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNode Address Configuration\u003c\/td\u003e\n\u003ctd\u003eRotary switches (0–63) or software configuration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eTermination Type\u003c\/td\u003e\n\u003ctd\u003eScrew terminals\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEnclosure Rating\u003c\/td\u003e\n\u003ctd\u003eIP20\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eDIN Rail or Panel Mount\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOperating Temperature\u003c\/td\u003e\n\u003ctd\u003e0 to 55 deg C (32 to 131 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStorage Temperature\u003c\/td\u003e\n\u003ctd\u003e-40 to 85 deg C (-40 to 185 deg F)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eIsolation\u003c\/td\u003e\n\u003ctd\u003e1250 VAC rms between user power and DeviceNet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e52 x 104 x 42 mm (2.03 x 4.07 x 1.64 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.35 lbs (0.16 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003eQ: Can the 1790D-T16BV0 handle both PNP (sourcing) and NPN (sinking) sensors simultaneously? A: Yes.
