DEIF SCM‑1 Synchronising & Measuring Module

Technical Specifications

Model:SCM‑1

Brand:DEIF

System compatibility:Plug‑in synchronisation & measuring module for DEIF Delomatic‑3 DGU rack,communicates via backplane bus with CM‑1/CM‑2 main controller. It acquires generator and busbar three‑phase electrical signals,executes synchronisation check and breaker paralleling logic. Used in marine and offshore genset power management systems.

Function:Integrated measuring and synchronisation module. Samples generator three‑phase voltage and CT secondary current,busbar three‑phase voltage. Real‑time measures voltage,current,frequency and phase difference. Built‑in synchroniser logic,output relay or analogue control signals for governor speed and AVR voltage adjustment. Provides breaker closing command and breaker feedback monitoring. Configurable via DEIF PC service tool.

Installation:Plug‑in slot mounting inside Delomatic‑3 DGU rack,backplane bus connection,screw terminal block for PT/CT field wiring.

Interface:

‑Backplane internal communication bus

‑Generator three‑phase voltage input terminals

‑Busbar three‑phase voltage input terminals

‑Generator three‑phase CT current terminals(1A /5A secondary)

‑Relay / analogue output terminals for governor & AVR regulation

‑Breaker close command output terminals

‑Breaker status feedback input terminals

‑Front‑panel LED status indicators

Circuit feature:True RMS sampling,galvanic isolation for measuring channels,surge suppression for high‑voltage measuring terminals,non‑volatile memory for configuration parameters,hardware watchdog supervision.

Feature:Marine classification approved. Distinguished from SCM‑2: SCM‑1 supports both generator and busbar voltage inputs for synchronisation;SCM‑2 only has generator measuring circuit without busbar input. Legacy Delomatic‑3 series spare part.

Diagnostic:Front‑panel LED shows module power and bus communication status;measuring data and synchronisation conditions transmitted to main CM controller via rack backplane.

Power supply:Logic power supplied by rack backplane,typical power consumption 5W

Protection class:IP20 when installed in DGU rack

Horizontal operating temperature:‑25℃ ~ +70℃

Storage temperature:‑40℃ ~ +85℃

Relative humidity:5%‑95% non‑condensing

Shock & vibration:Complies with DNV marine environmental requirement

Weight:0.53kg

Dimensions:40.5mm ×234mm ×160mm

Certification:DNV,ABS,LR,CE,marine type approval

Built‑in function

SCM‑1 synchronising & measuring module collects generator and busbar electrical data for Delomatic‑3 power management system. It judges paralleling conditions and outputs closing signal for generator breaker,controls governor and AVR to match voltage and frequency before synchronisation. Widely used for ship and offshore generator automation cabinet spare‑part replacement.

Product Brief

SCM‑1 belongs to DEIF Delomatic‑3 series spare‑part family,rack‑mount synchronisation and measuring module. It needs to work with CM‑1/CM‑2 main controller inside DGU rack. Module address and wiring must be verified before commissioning. Widely applied for marine power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
