Triconex 3626X Tricon CX Supervised Digital Output Module
32-POINT SDO
01
Product Summary
Triconex 3626X is a 32-point TMR supervised digital output module for the 8131X Tricon CX I/O expansion chassis. It receives voted output commands from the three processor I/O-bus paths and controls externally powered 24 V DC field loads. Its principal role is to turn a controller command into a field-output state while checking the electrical result of each configured point.
For each output, Triconex 3626X coordinates three switching paths around a common core. Field power enters at the external termination panel, passes through the cable and 9666X FET connector, and reaches the selected output switch before continuing to the load; the return path closes at the termination panel. Voltage and current feedback return to the module so the commanded state can be compared with the connected circuit.
Point supervision on Triconex 3626X is enabled only where the load circuit is designed for it. The module can distinguish open- and short-circuit conditions from a normal commanded state, while the Pass, Fault, Active, Field and point indicators separate module status from load status. The FET and external panel keep permanent field conductors outside the removable I/O-module position.

Product Functions - Supervised Output Drive
Product-specific focus
3626X turns voted Tricon CX logic into thirty-two field-output commands and supervises the selected load circuits.
Per-point supervision
Supervision can be enabled by point so open- or short-circuit thresholds apply only where the field circuit is designed for them.
Termination transfer
The 9666X FET and interface cable carry module outputs to the selected ETP without landing field conductors on the removable module.
04
Diagnostics and Protection - Output Load Faults
3626X combines channel diagnostics with self-protected output switching and visible module/load indication.
Load fault detection
A supervised point can report open or short conditions instead of treating every missing load current as a valid OFF state.
Switch protection
The output switches protect against overvoltage, overtemperature and overcurrent, so point fuses are not required on the listed termination path.
Local indication
Pass, Fault, Active and Load indicators identify module condition, while individual green and yellow LEDs show point state and field alarm.

Questions & Answers
Which termination hardware is required for 3626X?
The 32-point chassis connection uses the 9666X FET connector and a compatible 16-point ETP arrangement. Confirm the number of panels and interface cables for all 32 outputs.
Can every output on 3626X use supervision?
Supervision is configured per point. The connected load and ETP wiring must satisfy the selected open- and short-circuit diagnostic thresholds.
How should field power be sized for 3626X?
Calculate the simultaneous point current and keep each termination panel within its total current limit. Redundant field supplies should be applied to the termination arrangement defined for the module.
Does 3626X need point fuses?
The output switches are self-protected in the specified configuration. Any additional external protection must be coordinated with the load and termination design rather than added blindly.
What should be checked when 3626X shows a Load alarm?
Identify the affected yellow point indicator, compare the command state with field current and inspect the ETP, cable and load circuit. The module alarm alone does not identify which external connection is open or shorted.
Can 3626X be installed in the main chassis?
No. It is an I/O module for the 8131X I/O expansion chassis. The 8120X main chassis has processor and communication positions instead.
