More Information

Overview Manuals Diagnostics Compatibility Protection Application
  • 32-point commoned TMR output architecture for nominal 24 V DC field circuits
  • Programmable point supervision with selectable short/open-circuit detection thresholds
  • Tricon v10.2-and-later compatibility with 16-point commoned field termination panels

3625 is an Invensys Tricon 32-point TMR supervised or non-supervised digital output module for Tricon v10.2 and later systems.

Three isolated output channels receive their respective processor commands, and a fault-tolerant quad-voter applies the voted signal to each commoned 24 V DC field output. Voltage and current loopback circuits support online output and field-circuit diagnostics.

Before installation or replacement, verify the Tricon system version, compatible commoned termination panels, field-power arrangement, connected load, wiring, and programmed supervision thresholds.

Availability, condition, price, and shipping time for 3625 are confirmed during quotation.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

  • Voltage and current loopback circuits validate output-switch operation and provide field-state feedback to the module diagnostics.
  • Output diagnostic fault coverage tests the switching path every 60 ms; the published diagnostic glitch is 2 ms maximum and 200 µs typical.
  • Each point has an On/Off indicator and Load field alarm; module status indicators are Pass, Fault, Load, and Active.
  • 3625 can be installed only in Tricon v10.2 and later systems.
  • Low-density Tricon systems must be upgraded to v10.2.x or later before 3625 installation.
  • The module is compatible with 16-point commoned field termination panels and supports energize-to-trip and de-energize-to-trip applications.
  • Output switches are self-protected against over-voltage, over-temperature, and over-current, so field-termination fuses are not required.
  • Output switches include self-protection against inductive kick-back from connected field loads.
  • System-to-field isolation is 1,500 V DC minimum, while point supervision and short/open detection thresholds are programmable per point.
  • Emergency shutdown systems in process-safety installations
  • Burner management systems for boilers, burners, furnaces, and heaters
  • Fire and gas protection systems in high-hazard process facilities

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.
Can TRICONEX 3625A be used when the installed module is TRICONEX 3625?
The manufacturer documents 3625A as compatible with 3625 applications. However, 3625A divides field power differently, so confirm the existing termination-panel and field-power wiring before substitution.
Can supervised and non-supervised points be mixed on one TRICONEX 3625?
Supervision can be programmed per point, allowing both configurations within an approved application. Retain supervision wherever detection of field-circuit faults is required.
Why can an unused point on TRICONEX 3625 generate a Load alarm?
An open supervised point is interpreted as a missing load. Apply the approved termination or load treatment, and disable supervision only when permitted by the validated safety application.
Does a Load alarm on TRICONEX 3625 mean the module itself has failed?
Not necessarily. Check the field wiring, termination panel, field supply, and connected device before replacing the module, because a field-path problem can produce the same alarm.
Can TRICONEX 3625 output diagnostics disturb a sensitive field device?
Diagnostic testing can create brief output transitions. Review the final element’s response time and process consequence, and use a controlled test window if the load could react.
Can different point groups on TRICONEX 3625 use separate field-power supplies?
Do not assume independent point-group supplies because 3625 field power is commoned across all points. Follow the documented redundant-supply wiring; grouped field power is a 3625A distinction.
Can TRICONEX 3625 be replaced online without shutting down the Tricon system?
Triconex supports transfer to a healthy paired or hot-spare module, but replacement must follow the site-approved procedure. Confirm control transfer, module health, alarms, and field state before removal.
