Modular time relay iRTA delayed-action A9E16065

Modular time relay – precise delay control

This iRTA modular time relay, catalog number A9E16065, is a reliable solution for delayed switching of loads in electrical installations. The device from the Acti 9 series, designed by Schneider Electric, offers a wide range of time adjustment and is intended for both professional and home use. Its compact size (1 module wide on a DIN rail) makes it easy to mount in distribution boards.

Functionality and application

The iRTA relay allows you to set a switch-on delay in the range of 0.1 seconds to 100 hours. This is an ideal solution in situations where gradual starting of devices is needed, e.g. motors, heaters or lighting. This minimizes voltage surges and peak loads, which translates into a longer lifespan of devices and more stable operation of the installation. The analog operating principle ensures precise and repeatable operation.

Characteristics and benefits

• Wide control voltage range: The ability to power with both AC (24…240 V) and DC (24 V) voltage increases installation flexibility.
• Large delay range: Adjustment from 0.1 s to 100 h allows adaptation to various applications. Two independent time ranges (0.1…100s and 0.1…360000s) provide even greater control over the switching process.
• High accuracy: Accuracy +/- 10% of scale ensures precise device operation.
• Intended for professionals and end users: Easy mounting on a DIN rail and intuitive adjustment of settings make the relay user-friendly for both installers and people performing electrical work independently.
• Durability and reliability: Designed to operate in harsh environmental conditions (operating temperature -5°C to +55°C). Mechanical durability exceeds 5 x 10^6 switching operations, and electrical – 10 x 5 switching operations in category AC1.
• LED indication: The built-in LED indicates the device status – green color means on, and flashing indicates the duration of the time delay.
• Overload protection: The rated switching current is as high as 21 A at 250 V AC, providing effective protection of the circuit against overload.
• Universal mounting: Mounting on a standard 35 mm DIN rail facilitates integration with the existing electrical infrastructure.

The A9E16065 time relay is a solid and functional device that will find application in many areas – from home automation to industrial control systems. Its versatility and reliability make it the ideal choice for anyone looking for precise control over the load switching time.
