Water Treatment / Australia
For an Australian engineering company, VectorTech Controls supplied a coordinated automation cabinet set for an advanced wastewater treatment and membrane filtration unit. The delivery included a Siemens ET200SP remote I/O main control cabinet and a relay signal isolation / valve control interface cabinet, supported by electrical design, PLC/HMI/SCADA programming, FAT, remote debugging and final shipment.
Project Overview
This cabinet set was designed around automation signal handling, field device interface and process sequence control for a water treatment unit. The Siemens ET200SP cabinet manages distributed I/O and industrial communication, while the relay interface cabinet provides electrical isolation, terminal concentration and control interfaces for valves, pumps, auxiliary equipment and interlock signals.
The project scope is focused on the wastewater deep treatment / membrane filtration automation cabinet set, covering design, manufacturing, software integration, FAT, remote debugging support and final shipment delivery.
Main Platform
Distributed I/O architecture for structured field signal collection and control.
Control Power
Reliable control power layout with redundant DC power arrangement.
Interface Cabinet
Relay and terminal concentration for valve sequencing and field feedback.
Software Scope
Programming and integration support with FAT and remote debugging before shipment.
Cabinet Architecture
The project is best understood as a coordinated cabinet set: one Siemens remote I/O main control cabinet and one relay / terminal interface cabinet. This structure is common in water treatment systems where many field signals, valve feedback points and interlock circuits must be connected to a stable PLC control architecture.
Cabinet A
The main cabinet uses Siemens SIMATIC ET200SP distributed I/O, SITOP 24 VDC control power, industrial Ethernet communication and redundant DC power structure to support field signal acquisition and control logic.
Cabinet B
The relay cabinet concentrates intermediate relays, terminal blocks and low-voltage protection devices. It provides electrical isolation between the PLC / remote I/O system and field devices for valve open/close feedback, equipment fault signals and interlock circuits.
From Design to Shipment
VectorTech Controls supported the project from electrical design and cabinet manufacturing to software integration, FAT, remote debugging support and final shipment delivery.
