DEIF IOM4‑1 Universal Input‑Output Module

Technical Specifications

Model:IOM4‑1

Brand:DEIF

System compatibility:Universal plug‑in I/O module for DEIF DM‑4(Delomatic‑4) DGU rack,communicates via back‑plane DM‑4‑LAN bus with PCM4‑1 / PCM4‑5 core controller,expands analog and discrete signal points for genset power‑management unit.

Function:Combined input‑output module. 16 channels multi‑configurable inputs,jumper selectable for binary dry‑contact,0‑10V voltage or 0‑20mA current signal;12 potential‑free relay outputs;2 galvanically‑isolated 0‑20mA analogue outputs. Supports cable monitoring for binary inputs. Signal data exchanged with PCM main controller via rack back‑plane bus.

Installation:Plug‑in slot mounting inside DM‑4 DGU rack,6TE width back‑plane connection,rotary switch for module address setting,terminal block for field wiring.

Interface:

‑Back‑plane DM‑4‑LAN internal bus

‑16 multi‑configurable input terminals

‑12 relay output terminals(potential‑free contact)

‑2 analogue output terminals(0‑20mA)

‑Rotary address‑setting switch

Circuit feature:10‑bit A‑D conversion resolution,galvanic isolation for analogue circuits,surge suppression for field terminals,relay outputs fail‑to‑open under power‑loss condition.

Feature:Marine classification society approved,hot‑swap capable;relay contact rating 250VAC / 24VDC,8A resistive load;analogue output max load 500Ω. Note:IOM4‑1(hyphen) is official document naming variant of IOM4.1(dot),hardware is identical part.

Diagnostic:Front‑panel LED indicates module power and back‑plane bus communication status;channel fault information transmitted to PCM controller.

Power supply:Logic power supplied by PCM module via rack back‑plane,typical power consumption 4W

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 marine environmental requirement

Weight:0.48kg

Dimensions:30.5mm ×234mm ×160mm

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

Built‑in function

IOM4‑1 universal I/O module expands signal acquisition and control output capacity for DEIF DM‑4 marine power‑management system. It collects breaker feedback,transducer analogue signals and external alarm contacts,provides relay drive for breaker control and analogue output for external indication. Widely used for ship and offshore generator power‑station automation cabinets.

Product Brief

IOM4‑1 belongs to DEIF DM‑4 series marine power‑control‑system spare‑part family,rack‑mount universal I/O module for DGU rack. Identical hardware as IOM4.1,different document naming notation. Module address rotary switch and input jumpers must be correctly set before commissioning. Widely applied for marine power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
