◉
For reactive loads, switching power must be derated. The documented maximum for DC reactive-load operation is 37.5 W, equal to 25% of the 150 W maximum. The module is not recommended for shunt-diode intrinsic-safety barriers; the 3615E is the designated alternative for that application.
WHY 3614E FITS A PROJECT
Supervised 24 VDC output duty
The 3614E is suited to Tricon applications where the output circuit must operate within a supervised digital-output architecture. Its eight commoned outputs and 24 VDC operating range make the module relevant when the existing system configuration specifically calls for this output class.
01
Output matching
Confirm that the existing configuration requires 8 commoned supervised outputs.
02
Voltage matching
Check that the field circuit is within the 20–36 VDC module range.
03
Load review
Review carry current and switching power before replacing a module in an operating circuit.
04
Barrier application
Do not treat 3614E as the preferred choice for shunt-diode intrinsic-safety barrier applications.

PURCHASE & CONFIGURATION QUESTIONS
3614E FAQ
01 · Is 3614E the correct replacement when the existing output circuit is 24 VDC?
3614E is a 24 VDC nominal supervised digital output module with an operating range of 20–36 VDC and eight commoned outputs. Replacement should therefore be based on matching the existing system configuration and field-circuit requirements, not voltage alone.
02 · What should I verify before purchasing 3614E as a spare?
Verify the exact module designation, the eight-point commoned output arrangement, the 24 VDC class, the field load requirements, and the applicable termination arrangement. These checks help prevent a nominal-voltage match from becoming a configuration mismatch.
03 · Can 3614E handle higher-current field loads?
The documented maximum carry current is 0.5 A per point, with a 4 A surge rating for 10 ms. The specified maximum switching power for a resistive load is 150 W. Actual load characteristics should be checked before replacement.
04 · Is 3614E suitable for shunt-diode intrinsic-safety barriers?
No. The Tricon planning guidance specifically states that 3614E is not recommended for shunt-diode intrinsic-safety barrier applications. The 3615E is identified for those applications, so the barrier arrangement should be checked before ordering.
05 · Why does the 3614E switching-power rating matter when replacing an installed module?
The 3614E is rated at up to 150 W for resistive loads, while reactive DC loads require derating to 37.5 W. Checking the actual load type and switching duty is important when a spare module is being selected for an existing application.
