Eaton ARTU Remote Terminal Unit

The Eaton ARTU Remote Terminal Unit is a compact, ruggedised field-level RTU designed for SCADA and DCS integration of remote I/O in electrical substations, distribution automation, process plant utilities, and remote monitoring applications across Saudi Arabia. The ARTU-K30 provides 60 configurable I/O points — digital inputs, digital outputs, and analogue inputs — in a DIN-rail mounted housing, communicating upstream via Modbus RTU or DNP3 Level 2 to SCADA master stations and DCS platforms. DNP3 is the standard SCADA communication protocol specified by Saudi Arabia's SEC for transmission and distribution automation, and Modbus RTU remains the dominant protocol in Saudi Aramco and SABIC process plant SCADA systems — making the ARTU-K30 a universally applicable field RTU for Saudi Arabia's diverse utility and process automation landscape without requiring protocol gateways.

The ARTU-K30's wide power supply range of 12 V DC to 60 V DC covers both substation battery-backed DC distribution (typically 48 V DC in SEC substations and 24 V DC in process plant marshalling panels) without requiring a separate power supply module, reducing BOM cost and panel space in tight substation kiosks. The RTU's onboard data buffering stores up to 10,000 time-stamped events with 1 ms resolution when SCADA communication is interrupted — ensuring no loss of protection relay operation events, motor start/stop records, or alarm data during WAN link outages that occur at remote Saudi Arabian substation sites. The sealed IP20 housing with conformal-coated PCBs provides protection against the humidity cycling, dust ingress, and temperature extremes common in Saudi Arabia's outdoor substation kiosks and coastal distribution automation equipment rooms.

In Saudi Arabia's electrical utility sector, the ARTU is widely deployed by SEC for distribution automation at 33 kV and 13.8 kV substations across the Western, Central, and Eastern regions, where it provides remote monitoring of protection relay status, CB positions, transformer temperatures, and capacitor bank switching commands via DNP3 to regional SCADA master stations in Riyadh, Jeddah, and Dammam. Saudi Aramco engineering teams use the ARTU in process plant and gathering centre substation auxiliary monitoring — tracking utility feeder status, battery charger health, and UPS alarms — integrating all facility electrical health data into the plant's Modbus-based DCS without additional HMI hardware at each remote location.

Razz Middle East supplies and configures ARTU-K30 units for turnkey substation automation projects across Saudi Arabia, providing I/O configuration, Modbus/DNP3 register mapping, SCADA integration commissioning, and acceptance testing. Our team has specific experience with SEC DNP3 automation projects and Saudi Aramco process plant SCADA integration, and we maintain local stock in Riyadh and Dammam for urgent project requirements.
