Brodersen A/S · Authorised distributor
Brodersen A/S builds remote telemetry units, data loggers and control cabinets for critical infrastructure. eWorld supplies, configures and supports the full RTU32 range across the UAE, Saudi Arabia, Qatar and Oman — with regional stock, local engineering and post-commissioning support.
Brodersen has been building industrial control hardware from Copenhagen since 1969. It is not a general automation conglomerate — the company concentrates on one problem: getting reliable data out of, and control into, sites that nobody is standing next to. Substations, pumping stations, wellheads, trackside cabinets.
That focus shows in the engineering decisions. Where a general-purpose PLC treats communications as an add-on card, Brodersen's RTU32 platform treats the protocol stack as the product. IEC 60870-5-101 and -104, IEC 61850 client and server, DNP3 including WITS slave, Modbus, OPC-UA, MQTT and more ship inside the same device, unlocked by licence rather than by replacing hardware. For a utility running a mixed estate — a modern SCADA master talking to twenty-year-old field devices — that protocol breadth is often the entire reason the brand appears in a specification.
The install base backs it up. Thames Water selected Brodersen for a programme replacing roughly 8,500 obsolete telemetry units across its water and wastewater networks. German utility N-ERGIE deployed more than 1,700 RTUs communicating over IEC 60870-5-104 as part of a network control centre consolidation. Brodersen hardware also appears in projects delivered by ABB, Alstom, GE Vernova, Eaton and Larsen & Toubro.
Both series share the same firmware, the same WorkSuite programming environment, the same protocol drivers and the same LB2 I/O modules. The choice is about I/O scale and cabinet space, not about capability tiers.
Modular PLC / RTU
Compact all-in-one PLC / RTU
| Criterion | RTU32M | RTU32N |
|---|---|---|
| Architecture | Modular, backplane-based | Compact all-in-one |
| Typical I/O count | 8 to 1,000+ | Onboard I/O, expandable via LB2 |
| CPU redundancy | Yes — three redundancy modes | Not applicable |
| Hot-swap I/O | Yes | Yes, on LB2 expansion |
| Built-in display | No | Yes |
| Serial ports | Via communication modules | 4 onboard |
| Programming | WorkSuite — IEC 61131-3 (LD, FBD, ST, IL, SFC) | |
| Protocol stack | Identical across both series | |
| Best suited to | Substations, large plant, distributed I/O across a site | Outstations, pump stations, remote cabinets, retrofit |
Drivers are resident in the firmware on both series. Enabling an additional protocol is a licence key, not a hardware change — which matters when a SCADA master gets replaced mid-project and the interface requirement shifts.

Across the GCC, cybersecurity has moved from a design preference to a procurement gate. Saudi Arabia's National Cybersecurity Authority issued the Operational Technology Cybersecurity Controls (OTCC-1:2022) as a mandatory baseline for operators of critical OT environments — energy, water, transport and industry — and the framework translates IEC 62443 into national compliance language. In the UAE, comparable expectations reach field devices through utility and national infrastructure requirements.
For anyone specifying an outstation, the practical consequence is that the device's own certification status now forms part of the audit trail. Brodersen holds UL certification to IEC 62443-4-1 (secure development lifecycle) and IEC 62443-4-2 (component security requirements), alongside:
eWorld can supply the current certificate set as part of a tender submission. If your specification calls for a certification not listed here, ask — some are project-specific and issued on request.
Distribution and transmission substation automation, feeder automation, load dispatch centre integration, and gateway duty between legacy IEDs and a modern SCADA master.
Pump station control, reservoir and network level monitoring, pressure management, and large-scale telemetry outstation replacement programmes.
Wellhead monitoring, pipeline stations, tank farms and terminals — including hazardous-area installations under ATEX and IECEx.
Trackside and depot control cabinets, power supply monitoring and station systems, certified to EN 50121-4 for railway EMC environments.
Every datasheet in this industry is written for European conditions, and that gap causes real field failures here. Three things are worth checking before you commit a part number to a bid.
Ambient temperature is not enclosure temperature. A device rated to a given ambient will run considerably hotter inside a sealed enclosure in direct sun. Thermal management of the cabinet — not the specification of the device — is usually what determines whether hardware survives its second summer. Plan the derating calculation at design stage, not after the first failure.
Coastal installations corrode faster than the datasheet implies. Salt-laden humidity along the Gulf Coast attacks connectors and unprotected boards. Ask about conformal coating options and specify enclosure ingress protection against the actual site, not the nominal one.
Fine dust defeats filtration designed for European particulates. Sealed enclosures with passive cooling generally outperform filtered and ventilated designs at inland sites, provided the thermal budget is calculated honestly.
eWorld's engineering team can review a proposed cabinet design against site conditions before the order is placed. In our experience, this conversation is far cheaper than the replacement programme that follows when it doesn't happen.
The reason to buy Brodersen through a regional distributor rather than direct is what happens after the box arrives.
Yes. eWorld represents Brodersen A/S in [[list the exact territories covered by your agreement]]. Equipment is supplied new, with manufacturer warranty and full documentation. For territories outside our coverage, Brodersen's distribution page lists their other regional partners.
RTU32M is modular and scales from 8 to over 1,000 I/O with redundant CPU and power supply options. RTU32N is a compact all-in-one unit with onboard communications and a built-in display, expandable with the same I/O modules. Both run identical firmware, the same WorkSuite programming environment and the same protocol drivers — so a project can mix both without maintaining two skill sets.
In most cases yes, because the RTU32 platform supports the protocol suites those devices typically use — IEC 60870-5-101 and -104, DNP3 and Modbus. A migration still needs a point-list mapping exercise and a cutover plan. Send us the existing configuration and we will assess it before you commit to a retrofit.
OTCC-1:2022 applies to the operator, not to any single device — compliance is assessed across governance, defence, resilience and third-party domains. What device certification does is shorten the evidence path for the technical controls. Brodersen holds UL certification to IEC 62443-4-1 and 4-2, which is the component-level standard the framework draws from. We can supply the certificates for your compliance file.
Through Brodersen WorkSuite, which supports all five IEC 61131-3 languages: ladder diagram, function block diagram, structured text, instruction list and sequential function chart. Function blocks can also be written in C and C++. A trial version limited to 40 I/O is available for evaluation.
Often not. The RTU32 web server generates an HTML5 HMI that can be published as pages viewable from a browser on a tablet, phone or laptop — no additional panel hardware or SCADA client licence. RTU32N also carries a built-in display for local values including digitals, counters, analogues, supply voltage and internal temperature.
Yes. All drivers are already resident in the firmware. Adding one is a licence key applied through the RTU's web interface. The same applies to CPU speed, RAM allocation and tag count on RTU32M — which is why the platform suits projects where scope grows after the first phase.
Send us your I/O count, required protocols and site conditions. We will come back with a configuration, a price and a lead time — and tell you if a smaller unit would do the job.
