DEIF SMC‑C Speed Monitoring Control Module

Technical Specifications

Model:SMC‑C

Brand:DEIF

System compatibility:Special‑purpose rack‑mount speed monitoring module,applied for genset engine speed supervision. Collects magnetic pickup frequency signal,realises overspeed / underspeed monitoring. Supports Modbus RTU communication for SCADA data upload,works for marine and industrial generator sets.

Function:Speed measuring and supervision module. Receives frequency pulse signal from magnetic pickup sensor,converts frequency value into engine rotating speed. Configurable overspeed and underspeed threshold with independent time‑delay. Potential‑free relay outputs for alarm and trip command. On‑board rotary switch for module address setting. Transmits real‑time speed value and fault status via Modbus RTU bus.

Installation:Plug‑in slot mounting inside control rack,6TE width back‑plane connection,screw terminal block for sensor and field wiring.

Interface:

‑Back‑plane internal communication bus

‑Frequency input terminals for magnetic pickup sensor

‑Potential‑free relay output terminals for alarm and trip

‑RS‑485 Modbus RTU communication terminals

‑Rotary switch for module address setting

Circuit feature:Galvanic isolation for frequency input channel,surge suppression for field terminals,non‑volatile storage for supervision parameters,hardware watchdog monitoring.

Feature:Relay contact rating 250VAC / 24VDC,8A resistive load. Frequency measuring range 0‑10kHz. Module address must be set correctly before commissioning.

Diagnostic:Front‑panel LED indicates module power and communication status;overspeed / underspeed fault status output via relay contact and bus data.

Power supply:24VDC auxiliary power supply,typical power consumption 3W

Protection class:IP20 when installed inside equipment rack

Horizontal operating temperature:‑25℃ ~ +70℃

Storage temperature:‑40℃ ~ +85℃

Relative humidity:5%‑95% non‑condensing

Shock & vibration:Complies with industrial genset environmental requirement

Dimensions:30.5mm ×234mm ×160mm

Certification:CE

Built‑in function

SMC‑C speed monitoring module acquires pulse signal from magnetic pickup sensor for DEIF genset system. It monitors real‑time engine rotating speed,triggers alarm or trip output when overspeed or underspeed fault occurs. Widely used for industrial and marine generator cabinet speed‑supervision spare‑part replacement.

Product Brief

SMC‑C belongs to DEIF power‑control‑system spare‑part family,rack‑mount speed monitoring module for engine overspeed/underspeed protection. Magnetic pickup wiring and module address setting need to be checked before commissioning. Widely applied for power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
