DEIF OPM‑1 Output Relay Module

Technical Specifications

Model:OPM‑1

Brand:DEIF

System compatibility:Plug‑in relay output module for DEIF Delomatic‑3 DGU rack,communicates with CM‑2 main controller via back‑plane ARC‑net token‑ring bus. Expands large‑quantity discrete control output points for generator control unit.

Function:16‑channel potential‑free relay output module. Receives control commands from CM‑2 controller through ARC‑net bus. Relay contacts drive circuit‑breaker closing/tripping,engine governor,AVR,external alarm lamp and interlock actuators. Each relay status can be read back by main controller.

Installation:Plug‑in slot mounting inside Delomatic‑3 DGU rack,6TE width back‑plane 64‑pin connector connection,screw terminal block for field wiring.

Interface:

‑Back‑plane ARC‑net internal token‑ring bus

‑16‑channel potential‑free relay output terminals

‑Front‑panel LED status indicators

Circuit feature:Relay transient surge suppression,output contact status feedback monitoring,non‑volatile module ID storage,hardware communication watchdog.

Feature:Discontinued legacy marine rack‑mount module,classification society approved,hot‑swap capable. Relay contact rating:250VAC / 24VDC,8A resistive load. One DGU rack supports multiple OPM‑1 modules for output point expansion.

Diagnostic:Front‑panel LED indicates module power,ARC‑net bus communication and each relay channel operating status;fault information uploaded to CM‑2 controller.

Power supply:24VDC logic power supplied by rack PSM‑1 power module,typical power consumption 3.6W

Protection class:IP20 when installed inside DGU rack

Horizontal operating temperature:‑25℃ ~ +70℃

Storage temperature:‑40℃ ~ +85℃

Relative humidity:5%‑95% non‑condensing

Shock & vibration:Complies with DNV / GL marine environmental requirement

Weight:0.44kg

Dimensions:30.5mm ×234mm ×160mm

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

Built‑in function

OPM‑1 relay output module expands drive output capacity for DEIF Delomatic‑3 marine genset control system. It converts internal logic commands into relay contact signals to control breakers,alarm devices and executive components. Widely used for marine generator control cabinet spare‑part replacement.

Product Brief

OPM‑1 belongs to DEIF Delomatic‑3 series marine power‑control‑system spare‑part family,rack‑mount 16‑channel relay output module. Matches Delomatic‑3 DGU rack and CM‑2 CPU module. Widely applied for marine power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
