Electronic time relay 1W delayed dropout ETR2-12 262686

Time relay – reliable time control

The ETR2-12 electronic time relay is a compact device designed for precise time control in electrical circuits. Designed for both industrial and building automation applications, it offers a wide range of time settings and reliable operation. The device is distinguished by its versatility thanks to the possibility of powering it with both AC and DC voltage.

Functionality and application

The ETR2-12 relay is characterized by a delayed-off function, which means that after switching on the circuit, the timer delays the moment of switching off. This solution is ideal in applications requiring maintaining the state for a specified time, e.g. in lighting, ventilation or heating device control systems. The possibility of mounting on a TH rail facilitates installation and integration with existing systems. This relay will find application in:

• Lighting control (e.g. corridors, stairs)
• Building automation (e.g. blinds, gates)
• Ventilation and air conditioning systems
• Industrial machines and equipment requiring delayed circuit disconnection
• Applications where precise control of device operating time is needed

Technical characteristics and construction

The device, with a width of only 17.5 mm, a depth of 63 mm and a height of 70 mm, is characterized by a compact design. Made of high-quality materials, it ensures durability and resistance to environmental conditions (IP20 protection class). The relay has one changeover contact, which allows controlling various loads with a rated current of up to 3A. Screw connection ensures a secure and safe connection of wires. A wide time setting range from 0.05 seconds to 360000 seconds (100 hours) allows you to adapt the device to specific application needs. The rated control voltage Us is from 24 to 240V AC/DC, which increases its versatility in various electrical installations.

Additionally, it is worth mentioning the possibility of working in the temperature range from -25°C to +60°C, which makes it suitable for working in harsh industrial conditions.
