Triconex DI3301 is a Trident digital input module identified as model 3301 in the manufacturer guide. It accepts 32 commoned field inputs at nominal 24 VDC; the published operating range is 15–30 VDC.
Three internal channels acquire the field signals for the redundant system. The input delay is less than 10 ms, while 0–5 VDC is OFF and 15–30 VDC is ON; 6–14 VDC is the transition region. These boundaries must be checked at the field terminals.
Use the installed baseplate and field-interface records to specify the replacement. The force-to-value diagnostic test and permitted input toggle rate matter for fast signals. Preserve point mapping and carry out the approved input proof test after installation.

10 VDC falls in the published 6–14 VDC transition region. Do not design a valid binary state around that level; verify the field source and voltage at the terminals.
The manufacturer specifies commoned field inputs. Three internal acquisition channels provide system redundancy, which does not make every external point individually isolated.
The table distinguishes greater than 30 kΩ for the module alone from approximately 3 kΩ with the baseplate. Use the installed assembly value when evaluating a field source.
Its published operating input is 15–30 VDC. High-voltage applications require the manufacturer-specified external interface and baseplate arrangement; the module rating does not authorize a direct AC connection.
No. The manufacturer separately lists acquisition scanning and an input delay below 10 ms. Base the signal-response assessment on the applicable end-to-end delays.
The manufacturer requires input toggling below 20 times per second to maintain diagnostic fault coverage. A contact counter application must be assessed against that requirement.
The published test lasts less than 2 ms. Review the manufacturer test behavior and any parallel connected equipment before the approved commissioning test.
DI identifies the digital-input function; the manufacturer front panel and table use 3301. Record the exact installed unit label and revision, and avoid duplicating an order merely because a space was inserted.
Send the model, complete part number, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
