More Information

Overview Manuals Signal Match DeviceNet Setup Loop Check Application
  • Four single-ended 0–10 V analog inputs
  • DeviceNet base block with screw-clamp terminals
  • Supports two discrete expansion modules

1790D-TN4V0 places voltage acquisition and DeviceNet communication in one compact distributed-I/O node.

Its nonisolated channels depend on a sound shared reference and field supply, making grounding and cable routing central to measurement stability.

The base block can extend with discrete modules, but the scanner image and physical module order must agree with the installed assembly.

  • Restore the node address and baud rate
  • Match the scanner image and expansion order
  • Verify DeviceNet and field power independently
  • Apply a known voltage to each channel
  • Confirm engineering scaling in the controller
  • Check diagnostic and network status before release
  • Distributed voltage-transmitter acquisition
  • Compact machinery analog monitoring
  • DeviceNet expansion with mixed analog and discrete I/O
Description
Allen-Bradley 1790D-TN4V0 combines a DeviceNet adapter and four voltage-input channels in a CompactBlock LDX screw-clamp base block.

Each channel accepts a single-ended 0–10 V signal and converts it at 12-bit unipolar resolution, while the block exchanges I/O data and diagnostics through the DeviceNet connection.

Commissioning should verify node address and baud rate, separate DeviceNet and field supplies, common reference wiring, channel scaling, grounding, and any attached expansion modules before live signals are applied.

Technical notes
1790D-TN4V0 replacement requires matching 0–10 V single-ended inputs, DeviceNet node and baud settings, scanner mapping, separate field power, common wiring, and expansion order; a current-input block is incompatible.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Will Allen-Bradley 1790D-TN4V0 retain the existing DeviceNet scanner mapping after replacement?
Not automatically. Restore the documented node address, baud rate, scanner image, channel configuration, and expansion order before reconnecting the process.
Why can all channels on Allen-Bradley 1790D-TN4V0 show unstable values?
Inspect the shared reference, field-supply quality, grounding, shield routing, DeviceNet power, and whether signal wiring is mixed with noisy conductors.
What must be recorded before replacing Allen-Bradley 1790D-TN4V0?
Save the DeviceNet node address and baud rate, scanner configuration, input scaling, channel usage, field-supply arrangement, terminal labels, and expansion-module order.
What should be checked before moving existing field wiring onto Allen-Bradley 1790D-TN4V0?
Confirm the voltage-signal type, shared reference, field supply, terminal identification, cable shielding, grounding, and expansion-module order; do not reuse current-loop wiring assumptions.
How should Allen-Bradley 1790D-TN4V0 be checked after installation?
Verify network status, confirm every channel with a known voltage source, compare engineering scaling, and test any attached expansion modules before reconnecting the process.
Does Allen-Bradley 1790D-TN4V0 require field calibration?
The official technical data lists no calibration requirement, but the complete measurement loop should still be verified during commissioning.
Why can Allen-Bradley 1790D-TN4V0 appear healthy on DeviceNet while its analog values remain wrong?
A healthy network does not prove field power, common reference, signal polarity, scaling, or channel wiring; verify those items with a known source at each input.
