The published Tricon specifications state that the 3664 has 32 commoned output signals, a 16–30 VDC recommended operating range, 36 VDC maximum voltage, and up to 2 A per output point. The output switches are self-protected against over-voltage, over-temperature, and over-current.
Product Introduction (Anti-Template)
The TRICONEX 3664 is built for the output side of a Tricon safety control system, where discrete commands have to reach valves, solenoids, relays, and other field devices. It provides 32 commoned digital output signals at a nominal 24 VDC and uses a dual, serial architecture rather than a conventional single-channel PLC output arrangement.
One important procurement detail is easy to miss: the 3664 and 3674 look similar on paper, but their behavior under certain output faults is different. The 3664 is documented primarily for de-energize-to-trip control programs and is specifically not recommended for energize-to-trip applications because certain hardware faults can leave an output stuck OFF.

QC, Procurement & Logistics SOP
1) Inbound Verification
Check the front label for TRICONEX 3664 and verify the complete ordering code, revision, serial number, connector condition, housing, and PCB condition. Do not rely on a seller’s generic description; 3664 is frequently mislabeled online as an input module or analog output module.
2) Live Rig Testing
When a compatible Tricon test rack is available, verify module recognition, PASS/FAULT/ACTIVE status, individual output indicators, and representative output switching under a controlled load. The published specification provides individual On/Off status indicators and module-level PASS, FAULT, and ACTIVE indicators.
3) Output Verification
Test representative channels at the customer’s applicable field voltage and load conditions. Confirm that the output remains within the expected voltage/current range and that diagnostic behavior is reported correctly. Because the module can handle up to 2 A per point, the test load should be selected carefully rather than using an improvised short-circuit test.
4) QA & ESD Packaging
Use ESD-safe handling during inspection and packing. Protect the connector, front panel, and PCB from static discharge, mechanical shock, and moisture. Record the module’s serial number and visible revision before dispatch.
5) Procurement & Compatibility Check
Confirm the customer’s Tricon system version, existing termination arrangement, field voltage, output load, and safety application. The 3664 belongs to the Tricon v9–v11 hardware family documented for the DDO architecture.
6) Global Logistics & Export Compliance
Confirm the commercial invoice description, country of origin, HS classification, declared value, and destination import requirements before shipment. For industrial control hardware, use the actual product function and applicable tariff rules when determining the customs classification.
7) Secure Air/Sea Packaging
Pack the module in an ESD-safe bag with rigid cushioning around the housing and connector area. For international air freight, use a moisture-resistant outer carton and prevent the module from moving inside the package.
Technical Pitfalls & Integration Warnings
1) 3664 is a DDO module, not a DI module.
Some online listings incorrectly describe the 3664 as a 16-channel digital input module. The Tricon planning documentation identifies Model 3664 as a 32-point Dual Digital Output Module.
2) Do not confuse 3664 with 3674.
Both are 24 VDC, 32-point Dual Digital Output modules, but their specified output behavior under certain stuck-ON fault conditions differs. Verify the exact model before substitution.
3) Check the safety philosophy: de-energize-to-trip vs. energize-to-trip.
The Tricon documentation specifically states that Models 3664 and 3674 are not recommended for energize-to-trip applications, because certain hardware faults can result in an output remaining OFF. This is a system-safety consideration, not merely a wiring detail.
4) Verify field power and load current.
The recommended voltage range is 16–30 VDC, with 36 VDC as the maximum specified voltage. Each point is rated up to 2 A, with a 10 A surge rating for 10 ms. Field power and load characteristics must be checked before commissioning.
5) Do not assume a generic 24 VDC PLC output module can replace it.
The 3664 is part of the Tricon DDO architecture, including its diagnostics, termination arrangement, and safety-system behavior. A conventional PLC output card with similar voltage and channel count is not an equivalent replacement.
Frequently Asked Questions (FAQ)
Q1: What is the TRICONEX 3664 used for?
It is a 32-point Dual Digital Output module used in Tricon safety control systems to control discrete field devices.
Q2: How many outputs does the 3664 have?
The module provides 32 commoned digital output signals.
Q3: Is TRICONEX 3664 a 24 VDC module?
Yes. Its nominal voltage is 24 VDC, with a recommended operating range of 16–30 VDC and a maximum specified voltage of 36 VDC.
Q4: What is the maximum output current per point?
The published specification gives a maximum of 2 A per point, with a 10 A surge rating for 10 ms.
Q5: Is the 3664 a TMR output module?
No. The 3664 is specifically documented as a Dual Digital Output (DDO) module. It should not be described as a conventional TMR 32-point output module.
Q6: Can I replace a 3664 with a 3674?
Not automatically. Although both are 32-point, 24 VDC Dual Digital Output modules, their specified behavior under certain fault conditions differs. The application and safety philosophy must be checked before substitution.
Q7: Can the TRICONEX 3664 be hot-swapped?
Tricon DDO modules support hot-spare/online replacement capabilities in the applicable system architecture, but the actual maintenance procedure should follow the installed system documentation and site safety procedure.
