Overview
The 140DCF07700 is a Modicon Quantum PLC clock synchronization module that accepts a single DCF77 time-code input at 24 V, isolated via optocoupler, and carries UL 508 HazLoc certification for use in hazardous locations.
Lifecycle and sourcing
Schneider discontinued the 140DCF07700 on 2022-08-26; remaining units are sourced through surplus and broker channels. An RFQ confirms current availability and lead time.
How it compares
The 140ERT85410C is a same-series multifunction input module that also accepts a DCF77 clock signal but adds 32 discrete process inputs at 24...125 V with configurable input inversion, making it a higher-density alternative when additional I/O is needed alongside time sync.
