Compatibility & Replacement
Specified for Tricon v10.2 and later systems. The 3625A uses 16-point commoned field termination panels.
The 3625A is a modified version of the 3625 and is documented as fully compatible with 3625 applications.
Application & Fault Scenarios
Used inside a Tricon safety control system to provide discrete field outputs through a TMR output architecture.
LOAD fault
Check field power, load condition and termination wiring.
FAULT indication
Review module diagnostics and associated field conditions.
Output unavailable
Check configuration, wiring and field supply before replacing the module.
Installation & Field Connection
Chassis & slot
Confirm the configured chassis and logical slot before installation. Tricon I/O modules are mechanically keyed for their configured positions.
Termination panel
Digital output modules require a separate field termination assembly and cable interface to the controller backplane.
Field power
The 3625A separates field power into two 16-point groups with a common return.
Supply arrangement
Verify the field supply arrangement against the applicable installation documentation before commissioning.
Redundancy & Diagnostics
TMR architecture
Three redundant channels participate in the output architecture.
Output voting
Redundant output paths use voting to control the field output.
Loopback diagnostics
Voltage and current loopback circuitry supports output fault detection.
Point supervision
Supervision and short/open detection can be programmed per supervised point.
Before replacement, compare the installed system generation, termination arrangement, output configuration and field power setup with the applicable 3625A manual.
Delivery & Warranty
Frequently Asked Questions
Can the 3625A be used in a Tricon v9 system?
The manufacturer specifies the 3625A for Tricon v10.2 and later systems.
Is the 3625A a digital input or digital output module?
It is a 32-point TMR digital output module with a nominal 24 VDC output.
What is the difference between the 3625 and 3625A?
The 3625A modifies the field-power arrangement into two 16-point groups while retaining a common return and is documented as compatible with 3625 applications.
Does the 3625A require a termination panel?
Yes. Digital output modules require a separate field termination assembly with a cable interface to the controller backplane.
What should be checked before replacing a 3625A?
Check the system generation, slot, termination assembly, point configuration, field wiring and field power arrangement.
