+86 15359408275Earth Leakage Detector · Fail Safe Control / Safety Manager
Honeywell 10310/2/1, type number 10800, is an earth leakage detector for Fail Safe Control and Safety Manager DC systems. The module is powered from 24 VDC and supports approved monitoring arrangements for 24, 48, 60 and 110 VDC systems.
With no earth fault, the detector establishes an earth reference of approximately -12 VDC. An earth fault sets the internal latch and de-energizes the relay; the alarm remains latched until it is reset manually or through the Rst24 or Rst110 input.
The module includes a manual self-test and earth-connection monitor. Its DC, 1 Hz and 0.25 Hz modes support normal operation, applications with solenoids or relays, and field tracing of earth faults using approved test equipment.

Honeywell 10310/2/1, type 10800, is an earth leakage detector for FSC and Safety Manager DC systems.
Honeywell 10310/2/1 supports approved monitoring arrangements for 24, 48, 60 and 110 VDC systems.
An earth fault sets the internal latch in Honeywell 10310/2/1 and de-energizes its relay. The fault remains latched until a reset is applied.
Honeywell 10310/2/1 can be reset manually with switch 2 or remotely through a high level at the Rst24 or Rst110 input.
Honeywell 10310/2/1 includes a manual TEST position and an Earth2 test path for checking both the detector and its earth connection under the approved procedure.
The wiring and reset-input arrangement depends on whether the application monitors 24, 48, 60 or 110 VDC. Use the approved Honeywell connection diagram for the installed system.
Verify the complete type number, rack key coding, 24 VDC module supply, Earth1/Earth2 link, reset inputs, relay contacts and site wiring drawings.
No. Match the complete type, electrical ratings, key coding, monitored voltage arrangement, connector allocation and safety-system approval before replacement.
Provide the complete model, type number, quantity, monitored DC voltage, system family, rack position, destination and clear nameplate and connector photographs.
Send the complete Honeywell model, type number, quantity, monitored DC voltage, destination and nameplate photo. Identification details will be verified before availability and lead time are confirmed.
