        Features:

        • Provides eight commoned 48 VDC outputs with relay-based TMR voting and continuous field supervision.
        • Uses a five-volt secondary source to extend short-circuit detection while a commanded output remains off.
        • Requires at least 100 mA of connected load and a 1.25-amp fuse at each supervised termination path.
        Configured as the mint-green 48 VDC SDO module, 3617E combines eight commoned output points with hot-spare capability for Tricon chassis installations.

        Its optional regulated secondary supply extends diagnostic coverage by exposing shorted field loads during the de-energized state, a function not provided by the 115 VAC version.

        Select loads that remain within 1 A per point and meet the 100 mA supervision threshold; use the specified ETP, cable interface, and 1.25 A output fusing.

        Availability is subject to Apter Power inventory and sourcing confirmation.
        Verified resources for Triconex 3617E: 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.
        • Supervises 48 VDC shutdown coils whose field power, fuse and load continuity must remain observable during long dwell periods.
        • Distinguishes an open circuit from an energized load through the documented minimum-current threshold.
        • Adds de-energized short detection for DC trip circuits when the approved secondary supply is wired to the ETP.
        • The supervised output works with the dedicated 9667-910F termination hardware and its approved cable interface.
        • A regulated 5.00 VDC ±0.25 VDC auxiliary source is required when the installation needs the extended Off-state shorted-load diagnostic.
        • Secondary-power wiring remains separate from the main 48 VDC load supply and must follow the documented commoned-output arrangement.
        • Continuous loopback detects missing field power, a blown fuse and an open or disconnected load during normal operation.
        • The module reports a field short that energizes a load incorrectly and adds Off-state short detection when the auxiliary source is present.
        • POINT, PWR and LOAD indicators distinguish external-circuit faults from the internal PASS, FAULT and ACTIVE diagnostics.
        • The eight commoned outputs operate from 36–72 VDC and switch resistive loads up to 150 W.
        • Each point supports 1 A continuously and allows a 5 A surge for 10 milliseconds.
        • A 100 mA minimum load and 4 mA maximum leakage define the supported range for dependable supervision.
        Description
        Triconex 3617E provides eight commoned 48 VDC supervised outputs over a 36–72 VDC field range. Its TMR architecture receives three processor commands and passes the voted result through a quadruplicated mechanical-relay output switch.

        Continuous voltage and current feedback extends diagnostics beyond the module to the field circuit and connected device. With the optional 5.00 VDC ±0.25 VDC secondary supply, the circuit can detect a shorted load even when the output is commanded off.

        The module is rated for 1 A per point and 150 W resistive switching, with a 100 mA minimum connected load and a 1.25 A fast-acting fuse at each output. A separate external termination panel and cable interface are required for installation.

        Technical notes
        For 3617E, off-state shorted-load detection depends on the optional 5.00 VDC ±0.25 VDC secondary supply and the specified ETP wiring.

        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
        What diagnostic benefit does secondary power give 3617E?
        The 5 V secondary source lets the DC module detect a shorted field load even while the commanded output is Off.
        How does the 100 mA rule affect 3617E load selection?
        Connected load current must meet the documented minimum so open-load supervision can operate as intended.
        Which 48 VDC duties suit 3617E?
        It is intended for critical supervised trip, solenoid and relay circuits needing TMR control and field-fault detection.
        How is tested 3617E supply described in an offer?
        The quotation confirms exact model, revision, condition, test documentation, ETP compatibility, quantity and shipping terms.
        Why is a standard 48 VDC DO not equivalent to 3617E?
        The supervised relay architecture, minimum-load rule, secondary source, loopback diagnostics and ETP differ from a standard output.
        What wiring package supports a 3617E review?
        Send the main and secondary supply details, load resistance, inrush, ETP and cable numbers, fuse, point list and proof-test requirement.
