DEIF PCM4.4 Distributed Fieldbus Control Module

Technical Specifications

Model:PCM4.4

Brand:DEIF

System compatibility:8TE plug‑in distributed expansion controller for DEIF AWC400 wind turbine control system,communicates with main CPU PCM4.3 via ARCNET high‑speed bus. Works as remote field‑bus slave controller,expands distributed I/O and peripheral communication interfaces. Applicable for wind‑power generation,marine and offshore power management systems。

Function:Distributed field‑bus control module. ARCNET 2.5Mbit high‑speed communication for rack‑to‑rack data exchange. Three independent CAN bus channels(125‑250kbps),one RS‑485/422 serial port. Local digital input and relay output channels for peripheral logic. USB service port for parameter configuration. 2MB RAM,1MB Flash,32KB non‑volatile RAM for data retention. Executes distributed logic and transmits field‑device data back to main PCM4.3 controller。

Installation:Plug‑in slot mounting inside AWC400 control rack,8TE width back‑plane connection,screw terminal block for field wiring.

Interface:

‑Back‑plane rack power supply

‑ARCNET communication terminals(electrical / optical optional)

‑3 sets independent CAN bus communication terminals

‑RS‑422/485 serial communication terminals

‑Digital potential‑free contact input terminals

‑Potential‑free relay output terminals(250VAC /24VDC,8A)

‑USB service configuration port

‑Front‑panel LED status indicator lamps

Circuit feature:Industrial Linux kernel architecture,optocoupler isolation for field channels,surge suppression for terminals,non‑volatile memory for parameter storage,hardware communication watchdog supervision。

Feature:Distributed slave controller,does not act as main system CPU;main control logic runs on PCM4.3. Module address and ARCNET bus termination must be correctly set during commissioning。

Diagnostic:Front‑panel LED reflects module power‑on status and ARCNET/CAN bus communication fault;operating status accessible via service port or system bus.

Power supply:18‑36VDC auxiliary power,max 6A consumption

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 wind‑turbine and marine environmental requirement

Weight:0.55kg

Dimensions:40.5mm ×234mm ×160mm

Certification:CE

Built‑in function

PCM4.4 distributed controller undertakes remote field‑bus data collection and local auxiliary logic for DEIF AWC400 system. It expands system control capacity via ARCNET link to main PCM4.3,reduces main‑CPU load for large wind‑farm or complex marine power‑plant. Widely used for wind‑turbine and marine power‑control cabinet spare‑part replacement

Product Brief

PCM4.4 belongs to DEIF AWC400 series spare‑part family,distributed field‑bus expansion controller. It cannot work standalone,must cooperate with PCM4.3 main CPU. ARCNET bus termination and module address setting need to be verified before commissioning. Widely applied for power‑equipment maintenance and renovation. ESD anti‑static protection shall be followed during installation.
