3RQ3052-1SM40
The Siemens SIRIUS 3RQ3052-1SM40 is an optocoupler transistor output coupling module with an input of 24V DC, an output of up to 60V DC, a rated current of 2A, screw terminal wiring, no mechanical contact wear, and is suitable for DC load signal coupling and high-frequency switching applications.
Product Positioning
The 3RQ3052-1SM40 belongs to the SIRIUS 3RQ3 semiconductor output coupling series. It uses an optocoupler with a transistor output to convert a 24V DC control signal into a switching action for a DC load. It is suitable for applications requiring long life and high-frequency switching.
Core Product Advantages and Features
Optical coupler isolation design
The input and output are isolated by optocouplers, with no mechanical contacts, which can withstand high switching frequencies and extend service life.
Transistor output
The output stage uses a transistor switch with a rated current of 2A and a maximum output voltage of 60V DC, suitable for driving DC loads or downstream controllers.
Complementary to 3052-1SM50
Both are part of the 3RQ3052 series, with transistor outputs for DC loads, and can be selected from the TRIAC version according to application requirements.
Narrow screw terminal design
With a housing width of only 6.2mm and screw terminal wiring, it is easy to install densely within the control panel.
