PLC accessories are devices and gadgets required for the optimum performance of a programmable logic controller. The category spans PLC modules, PLC connectors, PLC cable assemblies and PLC racks, together with power supplies, memory cards, programming software and mounting hardware. These accessories include interface splitter boxes, communication cassettes and front connectors. The type of PLC you're using will determine the accessories needed.
RS Australia stocks PLC accessories for every major controller platform, including PLC modules and PLC cable assemblies from Siemens, Omron and more. Browse what you need and enjoy fast nationwide delivery.
Types of PLC Accessories
RS Australia stocks a complete range of accessories for your control setup, allowing procurement teams to source essential modules, connectors, cables, racks, and power supplies from a single trusted distributor. Because programmable logic controllers adapt to diverse industrial architectures, selecting the right hardware depends directly on your system size, required I/O capacity, and environmental constraints:
- PLC Cables & Connectors: Provides essential signal and data communication across your automation network using dedicated HMI interface leads, USB programming lines, industrial Ethernet cables, and robust PLC connector options.
- PLC Expansion Modules: Expands processing capability by conditioning specialised data inputs, such as strain gauge weight monitoring, and feeding critical real-time information back to the central processor.
- PLC I/O Modules: Functions as the primary communication bridge between the central processor and field devices, serving as core PLC modules that process input signals and execute output commands.
- PLC Power Supplies: Delivers regulated, low-voltage DC power to connected system hardware while offering integrated switches for mode selection, memory protection, and backup battery maintenance.
- PLC Programming Software: Supplies the foundational instructions and code required by the CPU to monitor, control, and automate complex machinery across the plant floor.
- PLC Racks & Enclosures: Serves as the structural framework for mounting modular system components, featuring versatile DIN-rail and panel chassis configurations across various PLC racks to securely hold hardware together.
- PLC Training Manuals: Offers visual instructions and operational guidelines to assist engineers and technicians with system setup, programming logic, and quick field diagnostics.
Industrial Applications of PLC Accessories
RS supplies PLC accessories to various industrial sectors across Australia.
- Water & Wastewater Treatment: PLC racks and analogue I/O modules handle pump control, level monitoring, and dosing, while communication connectors link remote pump stations to a central SCADA system.
- Metallurgy & Metals Processing: High temperatures and electrical noise call for shielded PLC cable and extended-temperature modules, with expansion modules adding thermocouple inputs for furnace and ladle monitoring.
- Packaging & Bottling: High-speed lines need fast digital I/O modules and secure PLC connectors between controller and servo drives, specifying continuous-flex cable wherever the run enters a moving axis.
- Automated Manufacturing & Mining: Dust, vibration, and washdown drive the choice of rack, enclosure, and cable gland, with Australian mine sites specifying ruggedised assemblies for remote, hard-to-service locations.
- Building Services & HVAC: Communication modules link plant controllers to a building management system, while interface relays protect PLC outputs from inductive loads.
