Why Choose the ABB RBR101R-24VUC Interface Relay?
The ABB RBR101R-24VUC, order code 1SNA645519R0600, is a compact R600 interface relay designed for reliable electrical isolation, signal matching and load switching in industrial automation and control systems. The RBR101AR configuration operates from a 24 V AC/DC control supply and provides one normally-closed contact with a switching range from 10 mA up to 6 A.
As part of the ABB R600 boxed interface relay range, the RBR101R-24VUC provides a practical interface between electronic controllers such as PLCs and field-level electrical circuits. Its spring-terminal connection technology supports secure, efficient panel wiring, while an integrated LED provides clear visual indication of relay coil energisation.
The relay incorporates an RC circuit connected in parallel with the output contact for integrated output-contact protection. With a contact voltage range up to 250 V AC, an IP20 degree of protection and a compact 12 mm-wide housing, it is well suited to densely populated industrial control cabinets.
