3RQ3052-1SM50
The Siemens SIRIUS 3RQ3052-1SM50 is an optocoupler semiconductor output coupling module with a TRIAC three-terminal AC switch output. It has an input of 24V DC, an output of 20-264V AC, a rated current of 2A, and screw terminal wiring. It has no mechanical contacts and is suitable for signal coupling applications that require high switching frequency and long life.
Product Positioning
The 3RQ3052-1SM50 is a semiconductor-type output coupler in the SIRIUS 3RQ3 series. It uses an optocoupler with TRIAC output to replace traditional mechanical contacts, and can convert 24V DC control signals into AC load switching actions.
Core Product Advantages and Features
Optical coupler isolation
The input and output circuits are completely isolated by optocouplers, reducing noise interference and extending service life, eliminating concerns about mechanical contact wear.
TRIAC three-terminal AC output
The output adopts a three-terminal AC switch (TRIAC), with a rated current of 2A and an output voltage range of 20-264V AC, which can directly drive AC loads.
High switching frequency
Semiconductor outputs can withstand higher switching frequencies, making them suitable for use in automated control loops that require frequent operations.
Narrow design saves space
With a housing width of only 6.2mm and screw terminal wiring, it is easy to install in the existing DIN rail space inside the control panel.
