        Features:

        • Covers 120 VDC service from 90 to 150 VDC across three suffix-specific wiring versions.
        • Provides 0.8 A per point with a four-amp, ten-millisecond transient rating for each output.
        • Differentiates non-commoned 3603B from commoned 3603E/3603T termination designs.
        The current ordering group contains 3603B, 3603E, and 3603T, three blue-coded 120 VDC TMR output configurations with distinct commoning and isolation choices.

        These modules operate high-voltage DC devices through a voted output path, while voltage feedback and individual field fuses expose discrepancies between commanded and measured output states.

        Before replacement, select the exact suffix, confirm whether the field circuit is commoned, and verify the one-amp point fuse, ETP, cable, and 120 VDC load characteristics.

        Availability is subject to Apter Power inventory and sourcing confirmation.
        Verified resources for Triconex 3603B/3603E/3603T: 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.
        • Controls 120 VDC actuators and interposing relays used in high-integrity process shutdown sequences.
        • Supports projects that must choose explicitly between non-commoned B wiring and commoned E or T circuits.
        • Provides field-voltage mismatch detection for high-voltage DC loads where point status alone is insufficient.
        • The B configuration provides non-commoned outputs, whereas the E and T configurations use commoned field circuits.
        • Point isolation is rated at 1,500 VDC for the B and E variants and 2,500 VDC for the T variant.
        • The selected suffix must match chassis keying, termination-panel commoning and the field-circuit separation shown in project drawings.
        • All sixteen outputs operate across the 90–150 VDC field range and support 0.8 A continuously per point.
        • A 4 A transient is permitted for 10 milliseconds to accommodate brief DC load inrush within the approved circuit.
        • Typical on-state voltage drop remains below 1.5 V, while maximum load leakage is limited to 2 mA.
        • The 3603T variant is identified among Tricon equipment qualified for nuclear 1E applications under the documented qualification program.
        • Nuclear qualification remains tied to the exact T suffix, approved termination hardware and the project’s controlled qualification records.
        • The B and E variants follow their standard Tricon installation specifications and must not be represented as nuclear-qualified substitutes.
        Description
        Triconex 3603B/3603E/3603T covers the 16-point 120 VDC TMR digital-output variants used in Tricon control and safety applications. All three versions apply processor voting and source current to the field, but their point commoning and isolation arrangements are not identical. The shared voltage family therefore describes electrical duty only and does not make the B, E and T suffixes mechanically or functionally interchangeable.

        3603B provides non-commoned outputs, while 3603E and 3603T use commoned field circuits. Voltage loopback checks every output switch against its voted command, and LOAD/FUSE indication separates a field-voltage discrepancy from normal point status or an internal module diagnostic. The documented continuous-current, surge, voltage-drop and leakage limits must be considered together when selecting coils or other DC loads for each point.

        A replacement must preserve the installed suffix, chassis keying, interface cable, fuse rating and termination-panel design shown in the project drawings. The T configuration carries the higher point-isolation rating and a qualified application relationship, so it requires the matching project documentation as well as compatible hardware. Before transfer to a hot spare, confirm commoning, field-polarity, load inrush and external power continuity instead of relying only on the 120 VDC nameplate range.

        Technical notes
        3603B is non-commoned, while 3603E and 3603T are commoned; do not interchange suffixes until the ETP wiring and required 1,500/2,500 VDC isolation are verified.

        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.
        VIEW ALL FAQS
        Which commoning choice separates 3603B/3603E/3603T variants?
        3603B is non-commoned, while 3603E and 3603T use commoned output arrangements.
        Why would a project select the T member of 3603B/3603E/3603T?
        The 3603T raises point isolation to 2,500 VDC compared with 1,500 VDC for the B and E versions.
        What field duty suits 3603B/3603E/3603T?
        The family switches 120 VDC loads requiring TMR voting, point supervision and controlled high-voltage DC termination.
        How is suffix-specific stock checked for 3603B/3603E/3603T?
        Apter Power quotes the exact B, E or T module after confirming commoning, isolation, condition, quantity and delivery.
        Can the B and E members of 3603B/3603E/3603T share an ETP automatically?
        No. Their non-commoned and commoned circuits require the correct field-termination design and cable before any interchange.
        Which load values should be sent for a 3603B/3603E/3603T review?
        Provide steady current, ten-millisecond inrush, field voltage, leakage sensitivity, fuse, ETP, cable and required isolation.
