3RQ3118-2AB01 SIEMENS Coupler Plug Relay

Review SIEMENS New Output Coupler Plug-in Relay

The Siemens 3RQ3118-2AB01 is a versatile and reliable coupler plug-in relay designed for various automation applications. This device, manufactured by Siemens, is a key component in electrical control systems and allows for the selective switching of loads based on the status of other circuits.

The 3RQ3118-2AB01 is a 3-pole, 2-contact, normally open (NO) relay, meaning it has three active poles and two contact outputs. Each pole can be independently controlled, allowing for complex switching operations. The normally open configuration signifies that the contacts are open when no current flows through the coil. Once the coil is energized, the contacts close, making a connection between the input and output circuits.

The dimensions of this compact and robust relay are 54.6 mm (W) x 88.9 mm (H) x 34.5 mm (D). Its compact size makes it suitable for installation in various control panels and systems with limited space. The relay's contact rating is 10A at 250V AC or 30V DC, ensuring it can handle modest loads.

The 3RQ3118-2AB01 offers excellent electromagnetic compatibility (EMC) and is designed to meet the EN 61850-2-2 and EN 55022-B11 standards. This ensures that the relay can operate effectively in industrial environments with high electromagnetic interference.

The relay comes with a transparent protective cover, which helps to shield the contacts from dust, moisture, and accidental contact. The cover can be easily opened for servicing or replacement of the contacts, if necessary. The terminal block is accessible without removing the cover, making maintenance and installation more convenient.

The Siemens 3RQ3118-2AB01 coupler plug-in relay is a dependable solution for various automation requirements, offering efficient and selective switching capabilities in a compact and robust design.

The Siemens 3RQ3118-2AB01 coupler plug-in relay is an electrical component used for controlling circuits in various applications, particularly in industrial automation and power distribution systems. Like any other product, it has its advantages and disadvantages.
