PRODUCT DESCRIPTION
3624 - Supervised Digital Output Module
Triconex 3624 is a nominal 24 VDC TMR supervised digital output module with sixteen commoned outputs. It provides per-point load supervision and self-protected output switches for the documented field circuits.
Use the recommended 16-30 VDC range and verify the minimum 30 mA load, maximum 0.7 A continuous current and non-disableable output diagnostics. Commoned wiring and supervision requirements must match the installed termination arrangement.
Use the recommended 16-30 VDC range and verify the minimum 30 mA load, maximum 0.7 A continuous current and non-disableable output diagnostics. Commoned wiring and supervision requirements must match the installed termination arrangement.
BEFORE YOU BUY
Check the complete installed configuration
ACTUAL APPLICATIONS
Where 3624 supports field I/O tasks
The manufacturer documents the following circuit functions. Validate the complete safety function and field wiring before service.
-
01 · SUPERVISED LOADS
Operate monitored DC final elements
Command approved DC loads while retaining per-point load supervision. Match the connected current to the 30 mA minimum and 0.7 A maximum before accepting the circuit. -
02 · CIRCUIT INTEGRITY
Detect field-circuit abnormalities
Use the documented load and power indications to investigate field-circuit conditions. The off-state short-circuit detection threshold is below 5 ohm; verify the complete termination and return path. -
03 · REDUNDANT MAINTENANCE
Check active and spare output indications
During controlled maintenance, distinguish the primary module from its spare when reading the point LEDs. The manufacturer states that only the primary module asserts the point indicators.

SYSTEM CONFIGURATION
Match the installed field I/O arrangement
Triconex 3624 is a nominal 24 VDC TMR supervised digital output module with sixteen commoned outputs. It provides per-point load supervision and self-protected output switches for the documented field circuits.
Use the recommended 16-30 VDC range and verify the minimum 30 mA load, maximum 0.7 A continuous current and non-disableable output diagnostics. Commoned wiring and supervision requirements must match the installed termination arrangement.
Document field wiring and the approved application settings before exchange. Use the complete Tricon system installation procedure and verify affected circuits after replacement.
Features:
- 16 commoned supervised outputs
- 16-30 VDC recommended field range
- 30 mA minimum connected load
The 3624 requires field configuration and installation checks before system integration and commissioning.
INTERCHANGEABILITY
Verify the complete replacement identity before commissioning
Preserve the exact 3624 identity and the installed field termination. A similar Tricon module number does not establish interchangeability.
Use the recommended 16-30 VDC range and verify the minimum 30 mA load, maximum 0.7 A continuous current and non-disableable output diagnostics. Commoned wiring and supervision requirements must match the installed termination arrangement.
Retain the validated safety logic and proof-test records. Recommission affected channels under the approved site procedure.
Features:
- 16 commoned supervised outputs
- 30 mA minimum connected load
- Self-protected output switching
The 3624 requires replacement verification of field wiring, load or signal limits, termination and configured diagnostics before commissioning.

FREQUENTLY ASKED QUESTIONS
Questions buyers ask about 3624
Direct answers about identity, compatibility, stock, warranty, payment and shipping.
-
Can a 10 mA electronic input serve as the only load on 3624?
It does not meet the stated minimum required load of 30 mA. The load and supervision circuit require engineering review before connection. -
Is the 36 V figure a recommended operating setpoint?
No. The recommended range is 16-30 VDC; 36 VDC is the maximum voltage. Design around the recommended range and the actual supply tolerance. -
Why does the spare module show no point LEDs?
The manufacturer notes that only the primary 3624 module asserts the point LEDs. Check primary/spare status before diagnosing dark spare indicators as a failure. -
Does 3624 need a replaceable fuse for each field point?
Its specification states field fuses are not required because the output switches protect against over-voltage, over-temperature and over-current. Follow the overall approved circuit-protection design. -
Can OVD glitching be disabled to suit a sensitive receiver?
No. The manual expressly states that OVD glitching cannot be disabled for 3624. Assess the receiver against the typical 500 microsecond and maximum 2 ms diagnostic pulse. -
At what resistance does off-state short-circuit detection apply?
The specified threshold is below 5 ohm. Include cable and termination resistance when investigating a short-circuit indication. -
How does the 4.8 A surge figure differ from the normal load limit?
The surge rating applies for 10 ms only. Maximum continuous current is 0.7 A per point, so the two ratings must not be interchanged. -
What distinguishes the front-panel Power and Load indications?
Power indicates the field-power condition while the module provides a separate Load indication per point. Diagnose these alongside Pass, Fault and Active rather than using a single LED as a full system-health test.
