Product Summary

Within Tricon v9–v11 systems, the Triconex 3674 is a 24 VDC dual digital output module. It receives voted output commands from the controller and drives 32 commoned field points for discrete actuators and indicators.

At the field interface, Triconex 3674 applies the voted command to a commoned 24 VDC output bank. The recommended supply is 16–30 VDC, with 36 VDC as the maximum input to the output circuitry; each point is rated up to 2 A and the bank allows a 10 A surge for 10 ms, so the load and supply are evaluated at both point and bank level.

Inside the command path, Triconex 3674 keeps the dual serial logic separate from the field switching stage. Individual On/Off LEDs identify point state, while Pass, Fault, Active, and field-alarm indicators distinguish module condition from a field-side load or fuse condition.

Product Functions

Triconex 3674 turns each voted digital command into a controlled 24 VDC field output while keeping the 32 points in their commoned arrangement.

Commoned point bank

All 32 output points share the field-return arrangement; the external load wiring must therefore match the commoned termination scheme.

Dual serial command path

Two serial output paths carry the command into the module logic before the field switch changes state.

Load switching

Each point switches its assigned load within the 2 A point rating and the stated surge limit.

Diagnostics and Protection

Triconex 3674 combines point-level indications with module diagnostics so a technician can distinguish a commanded output from a field-side alarm.

Point indication

One On/Off indicator is provided for each output point.

Field protection

The output switches protect themselves against over-voltage, over-temperature, and over-current.

Fault response

A detected stuck-off condition drives the affected point de-energized; the field alarm exposes a load or fuse condition.

Questions & Answers

How are the 32 Triconex 3674 outputs returned to the field supply?

For Triconex 3674, The points use a commoned output arrangement, so the connected loads share the assigned field-return organization rather than receiving unrelated independent returns. The termination scheme must match that commoning.

What is the difference between the point and bank current limits for Triconex 3674?

The 2 A value applies to one Triconex 3674 output point. The 10 A value is a 10 ms surge limit for the commoned output bank, so it cannot be used as a continuous point rating.

Which indicators separate a command from a field alarm for Triconex 3674?

For Triconex 3674, Each point has an On/Off indication, while Pass, Fault, and Active describe module status. The field-alarm indication adds a separate signal for a load or fuse condition.

How does the dual serial path reach a field load in Triconex 3674?

Two serial command paths enter the Triconex 3674 logic before the field switching stage changes the assigned output state. The serial command path and the load wiring therefore serve different parts of the module.

What protection is built into the output stage for Triconex 3674?

For Triconex 3674, The output switches are self-protected against over-voltage, over-temperature, and over-current. That protection describes the switch behavior, not the wiring arrangement of the commoned field bank.

What supply range should be applied to Triconex 3674?

For Triconex 3674, Use the recommended 16–30 VDC range at the field supply, with 36 VDC as the maximum input to the output circuitry. The load calculation still uses the individual point and bank limits.
