Impulse relay iTL-16-20-48 16A 2NO 48VAC/24VDC A9C30212

Pulse relay for lighting and electrical circuit control

The iTL-16-20-48 pulse relay is a reliable device designed to control lighting and other electrical circuits. This model, with catalog number A9C30212, features a double-pole design with two normally open contacts (2NO) and the ability to operate on both alternating current (AC) 48V and direct current (DC) 24V. It is a versatile solution, finding application in both industrial installations and residential buildings.

Construction and functionality

The iTL-16-20-48 relay is mounted on a standard DIN rail, making it easy to integrate with existing switchboards. The device is only 1 module wide, allowing for optimal use of space in control cabinets. It has manual operation, allowing for testing or manual switching of the circuit. Designed to work with various types of lighting - incandescent, halogen, fluorescent - offering a maximum switching capacity of 1600W for bulbs and 1300VA for fluorescent lamps (with the possibility of compensation). It provides effective protection of the circuit against overload and short circuit - like most circuit breakers in this class.

Technical parameters and application

This relay is distinguished by its high efficiency and reliability. The maximum switching current is 16A (at cos φ = 0.6), allowing it to handle devices with higher power consumption. Characteristic C allows it to react more slowly to short current surges, so it tolerates starting devices with a motor well. The rated switching current is also 16A. The device complies with IEC/EN 60669-1 and IEC/EN 60669-2-2 standards, guaranteeing its safety and quality. The ability to expand with auxiliary contacts further increases its functionality. The degree of protection IP20 (and IP40 in the housing) provides protection against touch and external interference. The relay is widely used in lighting control systems, where it allows you to turn lights on and off from multiple points or remotely.
