Products Description
DEIF SCM4‑1 Synchronisation‑Control‑Measuring Module P/N 100154635.2

Technical Specifications
Model:100154635.2(SCM4‑1)
Brand:DEIF
System compatibility:Plug‑in synchronisation‑control‑measuring module for DEIF DM‑4 DGU rack,communicates via DM‑LAN back‑plane bus with PCM4‑1 / PCM4‑5 main controller. It undertakes high‑precision sampling of generator and busbar electrical signals,provides independent hardware synchro‑check and advance‑closing logic for breaker paralleling. Suitable for marine and offshore genset power‑management system.
Function:Integrated measuring‑synchronisation‑protection module. Direct three‑phase AC voltage input up to 690V L‑L for generator and busbar;CT secondary input 1A / 5A. Measures voltage,current,frequency,power factor and phase angle,accuracy class 0.5. Embedded independent hardware synchro‑check function,calculates breaker closing advance time and outputs advance‑closing command. Supports fast hardware protection trip signal,monitors breaker feedback status. Front‑panel rotary switch sets module unique address,hardware jumpers configure partial function options.
Installation:Plug‑in slot installation inside DM‑4 DGU rack,8TE width back‑plane connector,screw terminals for PT/CT field wiring.
Interface:
‑Back‑plane DM‑LAN internal communication bus
‑Generator three‑phase voltage terminals(max 690V AC direct input)
‑Busbar three‑phase voltage terminals(max 690V AC direct input)
‑Generator three‑phase CT current terminals(1A /5A secondary)
‑Potential‑free contact for breaker advance‑closing command
‑Breaker status feedback input terminals
‑Rotary address‑setting switch and hardware configuration jumpers
‑Front‑panel LED status indicators
Circuit feature:2.5kV galvanic isolation for measuring circuits;surge suppression for high‑voltage measuring terminals;non‑volatile memory stores module configuration parameters;hardware communication watchdog;CT burden per phase 0.4VA max.
Feature:Marine classification society approved,hot‑swap supported. One DGU rack allows up to four SCM4‑1/SCM4‑2 modules,each module must occupy unique address. Distinguished from SCM4‑2:equipped with busbar measuring circuit and independent hardware synchro‑check advance‑closing function.
Diagnostic:Front‑panel LED indicates module power‑on and DM‑LAN bus communication status;measuring fault and synchronisation condition data uploaded to main CPU via back‑plane bus.
Power supply:Logic power supplied by rack main power unit,typical power consumption 5W
