3RH2122-2KB40
Siemens SIRIUS 3RH2122-2KB40 auxiliary coupling contactor relay, 2NO+2NC contacts, 24V DC coil, built-in surge suppression diode, spring-loaded terminal wiring, Size S00 standard size design.
Product Positioning
The 3RH2122-2KB40 is a SIRIUS series 24V DC coil-coupled contactor relay with a built-in surge suppression diode, suitable for use with PLC output modules.
Core Product Advantages and Features
2NO+2NC contact configuration
It provides two sets of normally open and two sets of normally closed contacts, which can simultaneously handle signal feedback and interlock control.
24V DC coil
The coil has a rated voltage of 24V DC and an operating range of approximately 0.7 to 1.25 times the rated value.
Built-in surge suppression diode
The coil integrates a suppression diode to reduce surge interference when the DC coil is de-energized.
Spring-type terminals
Spring-loaded terminals allow for screwless locking, enabling quick installation and making them suitable for connecting to PLC outputs.
