Miniature auxiliary contactor, 2NO/2NC, 24VDC control DILER-22-G-EA(24VDC) 189978

Miniature auxiliary contactor – reliable circuit control

This miniature auxiliary contactor, catalog number 189978 (DILER-22-G-EA(24VDC)), is a compact and efficient solution for controlling electrical circuits. Designed for both professional and end-user applications, it provides reliable operation and easy mounting on a DIN rail or with screws. Its wide range of applications makes it an ideal choice for installers and those looking for a solid element in automation systems.

Construction and functionality

This contactor is characterized by a 2Z/2R configuration, which means two normally closed and two normally open contacts. Control is performed using a 24VDC voltage, ensuring compatibility with a wide range of control systems. Made of high-quality materials, it guarantees long-lasting and trouble-free operation even in demanding conditions. The method of connecting the auxiliary circuit is based on screw connection, which simplifies and speeds up the installation process.

Key features and benefits

• Versatility: The ability to mount on a DIN rail or with screws provides flexibility in choosing the installation method.
• Reliability: Rated operating current of 3A (at 400V) and the ability to switch a current of 10A guarantee stable operation even under load.
• Safety: Compliance with IEC/EN 60947, EN 60947-5-1, VDE 0660, UL and CSA standards ensures safety of use and compliance with applicable regulations.
• Compact dimensions: Dimensions of 45 x 58 x 54 mm allow installation in limited space.
• Wide voltage range: The ability to operate at AC 50/60 Hz (17-500V) and DC (24-220V) increases the range of applications.
• Durability: Mechanical endurance of 20 million switching cycles ensures long device life.
• Purpose: Ideal for creating auxiliary circuits, control circuits and applications requiring reliable switching of loads.
• Application in various environments: Resistance to mechanical shocks and climatic conditions make the contactor usable in various industrial environments.

Technical parameters in practice

The rated operating current of 3A at 400V means that the contactor is suitable for controlling devices with moderate power consumption. The ability to switch a current of 10A allows for trouble-free starting of devices with higher starting current – the C characteristic allows it to react more slowly to short current surges, therefore it tolerates starting devices with a motor well. The 24VDC control voltage is a standard in many industrial automation systems, which facilitates the integration of the contactor with the existing infrastructure. Mechanical shock resistance (10g) and climatic resistance ensure reliable operation even in harsh industrial conditions.
