        Features:

        • Monitors earth leakage in 24, 48, 60 or 110 V DC installations.
        • Offers continuous, 1 Hz and 0.25 Hz earth-reference modes.
        • Latches an earth-fault condition and de-energizes the relay until reset.
        The module supervises the relationship between an otherwise floating DC supply and earth so leakage paths can be detected before they develop into a second earth fault or an unsafe control condition.

        It connects earth to -12 V relative to the monitored supply zero. The connection can be continuous or pulsed at 1 Hz or 0.25 Hz; the slower pulsed mode supports fault tracing with a suitable DC current clamp.

        Use the exact A5/A11 key coding and verify the monitored system voltage, output-contact duty and reset circuit before replacement. Digital-input earth-fault detection may require the documented reverse-diode module.

        Availability is reviewed against the exact 10310/2/1 order identity and requested supply condition; manufacturer lifecycle status: Active / Available from OEM.

        • An earth fault sets an internal latch and de-energizes the output relay. The latched indication remains until a local reset or a valid Rst24/Rst110 reset signal is applied.
        • A test resistor and the separate Earth2 connection check both detector operation and the integrity of the earth connection. An open Earth1-to-Earth2 link prevents the fault latch from setting during the test.
        • Includes a manual self-test and earth-connection integrity check.
        • Monitors earth leakage across 24, 48, 60, and 110 V DC installations.
        • A5 and A11 key coding must match the intended rack positions.
        • Output-contact duty and reset wiring require verification before module replacement.
        • Detects leakage before a second earth fault creates an unsafe control condition.
        • Maintains a -12 V DC earth reference when no fault is present.
        • Supports continuous or pulsed monitoring for fault tracing with a DC clamp.
        • Provides continuous DC, 1 Hz, and 0.25 Hz connection modes.
        • Requires 24 V DC supply, limited to 30 V DC and 60 mA.
        • Separate reset inputs accept 18–70 V DC and 40–130 V DC ranges.
        Description
        Honeywell 10310/2/1 The module supervises the relationship between an otherwise floating DC supply and earth so leakage paths can be detected before they develop into a second earth fault or an unsafe control condition. It connects earth to -12 V relative to the monitored supply zero. The connection can be continuous or pulsed at 1 Hz or 0.25 Hz; the slower pulsed mode supports fault tracing with a suitable DC current clamp.

        An earth fault sets an internal latch and de-energizes the output relay. The latched indication remains until a local reset or a valid Rst24/Rst110 reset signal is applied. A test resistor and the separate Earth2 connection check both detector operation and the integrity of the earth connection. An open Earth1-to-Earth2 link prevents the fault latch from setting during the test.

        Use the exact A5/A11 key coding and verify the monitored system voltage, output-contact duty and reset circuit before replacement. Digital-input earth-fault detection may require the documented reverse-diode module.

        Technical notes
        Before installing Honeywell 10310/2/1, match the A5/A11 key coding, monitored DC voltage, output-contact duty, and reset circuit; the documented reverse-diode module may be required for digital-input earth-fault indication.

        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
        Why is Honeywell 10310/2/1 needed in a floating DC system?
        The module supervises the relationship between an otherwise floating DC supply and earth so leakage paths can be detected before they develop into a second earth fault or an unsafe control condition.
        Which documented DC supply limits apply to Honeywell 10310/2/1?
        The manufacturer data specifies Supply as 24 V DC, maximum 30 V DC; maximum 60 mA; the installed arrangement must match that exact value.
        How do the earth-reference modes work in Honeywell 10310/2/1?
        It connects earth to -12 V relative to the monitored supply zero. The connection can be continuous or pulsed at 1 Hz or 0.25 Hz; the slower pulsed mode supports fault tracing with a suitable DC current clamp.
        What rack and circuit details must match before installing Honeywell 10310/2/1?
        Use the exact A5/A11 key coding and verify the monitored system voltage, output-contact duty and reset circuit before replacement. Digital-input earth-fault detection may require the documented reverse-diode module.
        How should buyers interpret the availability of Honeywell 10310/2/1?
        The page records Active / Available from OEM. Apter Power reviews the exact order identity and condition without presenting this as an OEM delivery promise.
        What evidence identifies a Honeywell 10310/2/1 document request?
        Submit the complete nameplate, Output contact (Maximum 115 V DC and 2 A), installed system evidence, condition, quantity and destination so the document and quotation match 10310/2/1.
