Multifunction relay 1W ETR4-69-A 031891

Multifunctional time relay – precision and flexibility in control

The ETR4-69-A relay is a versatile device designed for a wide range of applications in industrial and building automation. It offers advanced timing functions, enabling precise control of electrical circuits. Thanks to a wide range of supply voltages (24…240 V AC/DC) and the possibility of mounting on a TH rail, this relay is easy to install and integrate with existing systems.

Functionality and application

This multifunctional relay is not only about timing – it is a comprehensive tool for process control. It offers functions such as delayed switching on, switching off, pulse switching off, leading and trailing edge triggering, and flashing. The time setting range from 0.05 seconds to 360000 seconds (over 100 hours) allows it to be adapted to specific application needs. It is ideal for lighting, ventilation, heating control systems, as well as industrial applications requiring precise timing.

It will find application wherever reliable time control is needed:

• Motor control
• Building automation
• Alarm systems
• Production processes
• Lighting

Characteristics and benefits

The ETR4-69-A relay is distinguished by its solid construction and high reliability. It meets the requirements of IEC/EN 61812-1 and VDE 0435 standards, which guarantees safety and compliance with applicable regulations. Its compact dimensions (width 23 mm) allow for efficient use of space in control cabinets. Additional advantages include:

• Universal supply voltage: Possibility of powering with both alternating current (AC) and direct current (DC) – one device for different installations.
• Wide time range: From milliseconds to many hours – flexibility in selecting operating parameters.
• Multifunctionality: Many operating modes in one device – cost reduction and simplified installation.
• TH rail mounting: Quick and easy mounting without the need for additional tools.
• Durable construction: Ensures long life and reliable operation even in harsh industrial conditions.
• Protection class IP20: Protection against touching fingers and against the ingress of solid objects larger than 12.5 mm.
• Delayed/instantaneous reverse outputs: Increased flexibility in configuring control circuits.
