        Features:

        • Acquires thirty-two 5-24 V DC sinking input points.
        • Provides four programmable interrupt inputs with faster response.
        • Separates field groups from logic common with documented high-voltage isolation.
        The module converts thirty-two low-voltage field states into rack-readable logic for AutoMax or DCS 5000 application tasks.

        Each sinking input draws the documented field current when its device applies a valid DC level. Isolation separates the field groups from logic common, and the module transfers the resulting bit states across the rack backplane.

        Maintain the four-input common groups, field polarity, 57C375 cable/terminal arrangement and interrupt assignments. Isolate power before cable or module removal to prevent an unexpected input transition.

        Availability is reviewed against the exact 57C419 order identity and requested supply condition; manufacturer lifecycle status: Discontinued / Obsolete by OEM.

        • Four inputs can be configured as interrupts with a shorter maximum response time. The processor can therefore react to selected fast events without waiting for the normal input scan path.
        • The 5-24 V range suits proximity switches, contacts with an external source, machine-state signals and other low-voltage DC devices that match the sinking-input arrangement.
        • Transfers input states to the AutoMax processor over the rack backplane.
        • Preserves four-input common groups and programmable interrupt assignments.
        • Includes 32 sinking inputs, four of which support interrupts.
        • Accepts field signals from 2.7 to 24 V DC.
        • Transfers low-voltage field states into AutoMax or DCS 5000 logic.
        • Field groups remain isolated while bit states cross the rack backplane.
        • Interrupt inputs respond within 0.7 ms; standard inputs within 3.3 ms.
        • Groups four inputs under each isolated field common.
        • Provides 5000 V AC isolation between field and logic.
        • Draws 700 mA from the rack's +5 V backplane supply.

        VIEW ALL FAQS
        Which interlock designs benefit from Reliance Electric 57C419 inputs?
        The module converts thirty-two low-voltage field states into rack-readable logic for AutoMax or DCS 5000 application tasks.
        Which DC input range belongs to Reliance Electric 57C419?
        The manufacturer data specifies Input range as 2.7 to 24 V DC sinking inputs; the installed arrangement must match that exact value.
        How are signals isolated inside Reliance Electric 57C419?
        Each sinking input draws the documented field current when its device applies a valid DC level. Isolation separates the field groups from logic common, and the module transfers the resulting bit states across the rack backplane.
        What common-group wiring must be retained for Reliance Electric 57C419?
        Maintain the four-input common groups, field polarity, 57C375 cable/terminal arrangement and interrupt assignments. Isolate power before cable or module removal to prevent an unexpected input transition.
        Which lifecycle caution applies when sourcing Reliance Electric 57C419?
        The page records Discontinued / Obsolete by OEM. Apter Power reviews the exact order identity and condition without presenting this as an OEM delivery promise.
        What drawings are needed to quote Reliance Electric 57C419 correctly?
        Submit the complete nameplate, Backplane power (+5 V at 700 mA), installed system evidence, condition, quantity and destination so the document and quotation match 57C419.
