3RQ3050-2SM50
The Siemens SIRIUS 3RQ3050-2SM50 is a low-current optocoupler output coupling module with an input of 24V DC, an output of 10-60V DC, and a rated current of 0.5A. It features spring-loaded (plug-in) terminal connections and no mechanical contacts, making it suitable for high-frequency switching applications with low-current signals.
Product Positioning
The 3RQ3050-2SM50 is a low-current version of the SIRIUS 3RQ3 semiconductor output coupling series. It uses an optocoupler with a transistor to output a small current load signal of 0.5A and adopts spring-loaded terminals for easy and quick wiring.
Core Product Advantages and Features
Low current transistor output
With a rated output current of 0.5A and a voltage range of 10-60V DC, it has a lower current specification than the 3RQ3052 series and is suitable for small signal loads.
Optical coupler isolation
Optical couplers achieve electrical isolation between input and output, eliminating concerns about mechanical contact wear and allowing for high-frequency switching.
Spring-loaded terminal wiring
Using spring-loaded (insertion-type) terminals, wiring can be completed quickly without screws, shortening installation time.
Narrow shell design
With a housing width of only 6.2mm, it saves space for DIN rail mounting within the control panel.
