Impulse Relay ITL 1P 16A 48V AC 24V DC

The Schneider Electric Acti9 iTL A9C30211 impulse relay is a modular impulse relay with 1 pole, 16 A and 1 normally open contact (1 NO), designed mainly for controlling lighting circuits from one or more pushbuttons. It features a control coil compatible with 48 V AC at 50/60 Hz or 24 V DC and is easy to install on DIN rail in residential, commercial and professional electrical panels.

Its impulse operation allows the contact state to change each time the coil receives a momentary command. In this way, several pushbuttons can control the same load from different locations, making it a practical solution for corridors, stairways, common areas, commercial buildings and other installations where multiple control points are required.

Acti9 iTL 1-pole 16 A impulse relay

Reference A9C30211 belongs to Schneider Electric's Acti9 iTL range and features 1 pole with one normally open contact. Its rated current is 16 A and it supports operating voltages in AC from 24 to 250 V.

• Number of poles: 1P.
• Contact composition: 1 NO.
• Rated current: 16 A.
• Rated operating voltage: up to 250 V AC.
• Network type: AC.
• Frequency: 50/60 Hz.

48 V AC or 24 V DC control coil

The Schneider Electric A9C30211 can be operated using a control voltage of 48 V AC or 24 V DC. This dual option makes it easy to integrate into different automation and control circuits.

The control command must be carried out using a short impulse. Schneider Electric specifies an impulse duration between 50 ms and 1 second.

• AC control voltage: 48 V AC.
• DC control voltage: 24 V DC.
• AC control frequency: 50/60 Hz.
• Signal type: impulse.
• Impulse duration: 50 ms to 1 s.

Lighting control from multiple points

The iTL impulse relay is especially suitable for lighting circuits controlled from multiple pushbuttons. Each impulse received by the coil changes the contact state: one impulse switches the load on and the next switches it off.

This system simplifies installations where lighting would need to be controlled from numerous points, avoiding more complex switching and crossover configurations.

Typical applications include:

• Staircase and landing lighting.
• Corridors and circulation areas.
• Common areas in buildings.
• Retail premises and offices.
• Residential installations with multiple control points.
• Electrical automation and control systems.

Manual and remote control

In addition to impulse control, the Acti9 iTL allows manual operation directly from the device. The front ON/OFF indicator makes it easy to visually check the state of the impulse relay during commissioning, maintenance or troubleshooting.

The range design also allows remote control to be disconnected via selector, a particularly useful function during maintenance operations.

Compatible with illuminated pushbuttons

The A9C30211 supports control via illuminated pushbuttons. Schneider Electric specifies a current of up to 3 mA for this type of control, making it suitable for installations where pushbuttons include lighting indication.

High electrical durability

The impulse mechanism is designed to withstand a high number of operations over its service life. Schneider Electric declares electrical durability of up to:

• 200,000 cycles in AC-21 category.
• 100,000 cycles in AC-22 category.

The recommended maximum switching frequency is 5 operations per minute or 100 operations per day, according to the manufacturer's conditions.

Compact 18 mm modular format

The Schneider Electric iTL impulse relay features a compact design of 18 mm width, equivalent to a standard module, making it easy to install in electrical panels where space efficiency is important.

• Width: 18 mm.
• Height: 84 mm.
• Depth: 60 mm.
• Modular pitch: 2 x 9 mm.
• Mounting type: fixed.
• Support: DIN rail.

Quick DIN rail mounting

The A9C30211 is installed directly on DIN rail, making it easy to integrate alongside miniature circuit breakers, residual current devices, contactors and other modular Acti9 devices.

The iTL family also uses an accessory mounting system designed to allow flexible combinations without tools, expanding control and signalling possibilities when the installation requires it.

Electrical connection

The terminals are designed to provide a secure connection inside the electrical panel. Schneider Electric specifies a stripping length of 11 mm and a tightening torque of 1 Nm.

• Stripping length: 11 mm.
• Tightening torque: 1 Nm.

Insulation and surge withstand

The impulse relay has a rated insulation voltage Ui of 440 V AC and an impulse withstand voltage Uimp of 6 kV, providing suitable characteristics for use in low-voltage electrical installations.
