iTL impulse relays are used to control by pushbuttons lighting circuits consisting of incandescent lamps, low-voltage halogen lamps, fluorescent lamps and discharge lamps.

Closing of the impulse relay pole is triggered by an impulse on the coil
Having two stable mechanical positions, the pole will be opened by the next impulse
Can be controlled by an unlimited number of pushbuttons.
Zero energy consumption

In the dark about lighting circuit safety? Get some clarity with this power relay from Schneider Electric. It has a 1NO configuration and is designed for connection to 3mA push buttons, letting you turn lights on and off remotely. A switch on the front gives you a local, manual control option. Fitted with a coil, the device uses a relay-style switch to boost the safety of your circuits. It only needs a short pulse between 50ms and 1s to change contacts, making it an energy-efficient component. Use it with Acti9 series timers, remote indicators and centralised controls to actively protect your control circuits as they work.

• Clips easily onto a DIN rail for fuss-free installation
• Capable of five switching operations per minute to handle demanding applications
• Accepts rigid and flexible cable connections between 0.5 and 4mm² for versatility

• Offices
• Research laboratories
• Factories
• Public buildings

Although contactors and relays are both used for switching loads, they work slightly differently. An impulse relay switches each time a voltage is briefly applied. A contactor switches a circuit on when a voltage is applied and off again when this power is absent.
