Eaton ETR4 Electronic Timing Relay
The Eaton ETR4 Electronic Timing Relay is a compact, versatile DIN-rail mounted timing relay delivering 10 configurable timing functions within a standard 22.5 mm housing, designed for precise time-delay control applications in industrial automation panels, motor control centres, and process control systems across Saudi Arabia. The ETR4 accepts a wide supply voltage range from 12 V DC to 240 V AC without requiring different variants for different applications — a significant operational advantage for Saudi MCC panel builders who must maintain a single SKU across diverse voltage environments rather than stocking separate 24 V DC, 110 V AC, and 230 V AC variants. The relay's 10 selectable timing functions include on-delay, off-delay, flicker (on-first and off-first), star/delta changeover, single-shot, off-delay on signal removal, and interval timer modes, covering the full range of time-delay requirements encountered in HVAC, pump sequencing, conveyor systems, and motor starting control panels.
The ETR4's LED indicators provide clear visual status of power supply, relay output energisation, and timing cycle progress, allowing technicians to verify relay operation during commissioning without test equipment. The rotary switch setting mechanism with snap-lock positions provides reliable, vibration-resistant time setting that does not drift in the high-vibration environments of Saudi Arabia's industrial facilities — a practical advantage over potentiometer-based timers where vibration-induced setting drift causes nuisance trips and process upsets. The relay's output contact rating of 8 A at 250 V AC / 30 V DC provides direct switching capability for small motors, solenoid valves, pilot lamps, and auxiliary contactors without interposing relays in most applications, reducing wiring complexity and panel component count.
In Saudi Arabia's process and utilities sectors, the ETR4 is extensively used in motor star/delta starting panels for pumps and fans across SWCC desalination facilities, NWC water pumping stations, and Saudi Aramco process utility systems. The relay's off-delay function is standard in HVAC fan and pump control panels throughout Saudi Arabia's commercial and industrial buildings, maintaining ventilation airflow for a set period after occupancy sensors signal room vacancy — an energy saving measure increasingly specified under Saudi Arabia's energy efficiency standards. Saudi industrial panel builders in the Eastern Province consistently specify the ETR4 for its wide supply voltage range, long MTTF, and straightforward rotary switch configuration that minimises commissioning errors in the field.
Razz Middle East maintains volume stock of the ETR4-11-A and related ETR4 variants in Riyadh and Dammam, supporting volume orders from panel builders and spot requirements from maintenance teams. We supply with full technical datasheets, wiring diagrams, and application notes for common Saudi motor control centre and HVAC panel configurations.

Key Features & Benefits
- Universal 12 V DC to 240 V AC supply voltage range eliminates the need to stock separate variants for different panel voltages, simplifying inventory management for Saudi panel builders and contractors.
- 10 selectable timing functions including star/delta changeover, flicker, on-delay, off-delay, and interval modes cover the complete range of timing requirements in industrial motor control and HVAC panels.
- Rotary switch with snap-lock positions provides vibration-resistant time setting that does not drift in Saudi Arabia's high-vibration industrial environments, preventing nuisance timing faults.
- 8 A / 250 V AC output contact directly switches small motors, solenoid valves, pilot lamps, and contactors without interposing relays, reducing panel wiring complexity and component count.
- LED indicators for power, output energisation, and timing cycle progress allow commissioning technicians to verify relay operation at a glance without additional test equipment.
- Long MTTF and sealed rotary mechanism ensure reliable operation in dusty, high-humidity Saudi industrial and coastal environments throughout the full -25°C to +55°C operating range.
Industrial Applications in Saudi Arabia
- Motor star/delta starting panel control at SWCC desalination stations, NWC pumping stations, and Saudi Aramco process utilities, where reliable changeover timing prevents starting current damage.
- HVAC fan and pump off-delay control in commercial buildings throughout Riyadh, Jeddah, and Dammam, maintaining ventilation airflow after occupancy sensor signal removal per Saudi energy efficiency standards.
- Conveyor and production line sequencing panels in MODON industrial city manufacturing facilities requiring precise delay interlocks between equipment start sequences.
- Compressor unloading delay control in oil and gas upstream facilities, where start-delay functions ensure compressor unloading valve operation precedes motor energisation to prevent overloading.
- Alarm and annunciator panel timing in process plants and substations, providing confirmation delays that distinguish momentary from sustained fault conditions and reduce false alarms.
- Irrigation and landscape pump control systems in Saudi Arabia's large-scale agricultural and urban landscaping projects requiring adjustable interval timer control for zone sequencing.
