Featuring integrated DeviceNet network connectivity and removable terminal blocks, it converts digital control signals into 24 VDC outputs for solenoids, relays, indicator lights, and actuators.\u003c\/p\u003e\n\u003ch3\u003eSourcing Digital Output Architecture\u003c\/h3\u003e\n\u003cp\u003eThe 16 output channels provide sourcing (PNP) operation, driving connected load devices by switching 24 VDC positive voltage directly to each field output terminal. Built-in electronic protection guards the internal circuitry against overcurrent and short-circuit conditions, while LED status indicators display local channel state and communication health.\u003c\/p\u003e\n\u003ch3\u003eIntegrated DeviceNet Connectivity and Address Configuration\u003c\/h3\u003e\n\u003cp\u003eFeaturing an integrated DeviceNet network port, the base block operates directly as a node on standard fieldbus networks. Network node addresses (0 to 63) are selected via hardware rotary switches or configured digitally over the network using RSNetWorx for DeviceNet software. The unit supports automatic baud rate detection for 125 kbps, 250 kbps, and 500 kbps communication speeds.\u003c\/p\u003e\n\u003ch3\u003eMechanical Design and Bus Expansion\u003c\/h3\u003e\n\u003cp\u003eBuilt as an IP20 open-style module, the 1790D-T0B16 installs on standard 35 mm DIN rails or directly onto flat panel surfaces. It includes an integrated expansion connector that allows connection to CompactBlock LDX expansion modules, expanding total local I\/O channel density without requiring extra DeviceNet network addresses.\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-T0B16\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 Output Base Block\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNumber of Outputs\u003c\/td\u003e\n\u003ctd\u003e16 points, sourcing (PNP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eNominal Output 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\u003e10.2 to 26.4 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOutput Current\u003c\/td\u003e\n\u003ctd\u003e0.5 A per channel max (4 A per module max)\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: What type of field loads can the 1790D-T0B16 drive directly?
