More Information

Overview Manuals Applications Safety Certifications Field Termination

Features:

  • Controls sixteen isolated 115 VAC field points without a shared output common.
  • Handles a twelve-amp surge for one AC cycle while maintaining a two-amp maximum continuous rating per point.
  • Offers 1,500 VDC point isolation in 3601E and 2,500 VDC point isolation in 3601T.
The current ordering configuration covers 3601E and 3601T, the 115 VAC variants in the Tricon sixteen-point TMR digital-output range.

These modules source current to independently wired AC loads and use voltage feedback to reveal a switch, field-power, load, or fuse condition that conflicts with the controller command.

Before installation, identify the required isolation version, verify the 80-155 VAC operating range, and match every output conductor to the specified external termination panel and cable.

Availability is subject to Apter Power inventory and sourcing confirmation.

  • Switches 115 VAC solenoids, relays and shutdown devices from voted Tricon logic.
  • Provides high-integrity discrete actuation for burner management, emergency shutdown and machine-protection sequences.
  • Supports planned online maintenance where a correctly configured hot-spare position and ETP are available.
  • The non-commoned architecture keeps individual AC field circuits separated through the approved termination arrangement.
  • Point isolation is rated at 1,500 VDC for 3601E and 2,500 VDC for the 3601T configuration.
  • Field design must account for the specified chassis and load leakage when connecting sensitive coils or monitoring devices.
  • The 3601T variant is identified among the Tricon equipment qualified for nuclear 1E applications under the documented program.
  • Standard equipment specifications continue to apply where a nuclear-qualified model is selected for the approved installation.
  • Qualification does not make E and T suffixes interchangeable; the exact module, termination hardware and project documentation must agree.
  • Each output uses a 3 A fast-acting fuse located on the selected field termination panel.
  • Because the module sources current but does not create load power, the AC field source must be wired to every output point.
  • The E and T variants must be paired with the approved cable and termination-panel option for their commoning and isolation requirements.
Description
Triconex 3601E/3601T identifies the 16-point, non-commoned 115 VAC TMR digital output family used to energize individually separated field circuits. Three Main Processor commands enter a quadruplicated voter that resolves one result for each sourced output. The architecture supports critical AC loads while retaining distinct field returns and the diagnostic independence needed for Tricon safety and control applications.

Voltage loopback compares the measured field condition with the voted command even when the connected load is absent. Point indicators show commanded status, while PASS, FAULT, ACTIVE and LOAD/FUSE information helps maintenance personnel separate an internal channel event from a loss of field voltage or a fuse-related discrepancy. Each circuit is protected through the approved external termination arrangement rather than by a shared module-level field fuse.

The E and T variants share the documented 80–155 VAC operating range but differ in isolation rating and qualified installation scope. Selection must match the exact suffix, chassis keying, interface cable, termination panel and project fuse arrangement before exchange. Where the T version is used in a nuclear 1E application, the project qualification documentation remains part of the replacement boundary; a similar voltage label alone does not establish interchangeability with 3601E.

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.
How do 3601E/3601T differ in point isolation?
The 3601E specification lists 1,500 VDC, while the 3601T version raises point isolation to 2,500 VDC.
Which load behavior is acceptable for 3601E/3601T?
Each point is rated to 2 A with a twelve-amp surge for one AC cycle, subject to field fuse and cabinet limits.
Where are 3601E/3601T normally applied?
They drive isolated 115 VAC field devices that require TMR voting, output supervision and hot-spare service.
How does Apter Power qualify a 3601E/3601T request?
The offer identifies the exact E or T version, condition, ETP, cable, testing scope, quantity and delivery date.
Can a 24 VDC output card replace 3601E/3601T?
No. Field voltage, AC frequency, commoning, fuse, isolation, leakage and load behavior are fundamentally different.
What should be included with a 3601E/3601T manual inquiry?
Provide the exact E or T suffix, chassis slot, ETP and cable numbers, load current, inrush, field voltage and isolation requirement.
