Equipped with D-shell connectors for field signal wiring and built-in DeviceNet network communication, it processes sinking or sourcing DC input signals to interface field sensors directly with DeviceNet control systems.\u003c\/p\u003e\n\u003ch3\u003eD-Shell Termination and Universal Sinking\/Sourcing Inputs\u003c\/h3\u003e\n\u003cp\u003eThe 16 digital input points are arranged in two 8-channel groups (inputs 0–7 and inputs 8–15) accessed through D-shell connectors. Each channel group utilizes dedicated common terminals (Com 0\/Com 1 for inputs 0–7 and Com 2\/Com 3 for inputs 8–15), allowing each bank to be independently wired for either PNP sourcing or NPN sinking field sensors.\u003c\/p\u003e\n\u003ch3\u003eIntegrated DeviceNet Connectivity and Addressing\u003c\/h3\u003e\n\u003cp\u003eWith embedded DeviceNet network capability, the module operates as an independent network node. Node addresses (0 to 63) are selected via front-panel rotary switches or configured over the network. The base block automatically detects standard DeviceNet baud rates (125 kbps, 250 kbps, and 500 kbps) upon connection.\u003c\/p\u003e\n\u003ch3\u003eCompact D-Shell Form Factor and Expansion\u003c\/h3\u003e\n\u003cp\u003eFeaturing a compact IP20 open-style enclosure, the 1790D-16BV0 mounts onto standard 35 mm DIN rails or flat surfaces. An integrated expansion bus interface permits direct side-by-side connection to CompactBlock LDX expansion modules, allowing local I\/O expansion under a single DeviceNet node address.\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-16BV0\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 (D-Shell)\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 8-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\u003eInput Impedance\u003c\/td\u003e\n\u003ctd\u003e4.8 kilohms\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\u003eField Termination\u003c\/td\u003e\n\u003ctd\u003eD-Shell Connectors\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\u003eDimensions\u003c\/td\u003e\n\u003ctd\u003e102 x 51 x 36 mm (4.0 x 2.0 x 1.4 in)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.38 lbs (0.17 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: How does the 1790D-16BV0 differ from terminal-block CompactBlock LDX models?
