Weidmüller 8690120000 RCM570R24 relay 4We 24 V AC 6 A plug-in connection content_copy

The Weidmüller RCM570R24 is a plug-in industrial relay from the RIDERSERIES RCM, designed for use in control and automation technology. It is used for switching, amplifying, and duplicating digital signals under low electrical load conditions. Its compact size with dimensions of 29 × 22.5 × 28 mm allows for space-saving installation in enclosures and control systems. The relay features four AgNi changeover contacts (4 CO) and a 24-V-AC coil, ensuring reliable signal transmission. An integrated red LED status indicator visually displays the operating status, while a lockable and tactile test button enables easy functional testing.

Applications
This relay is suitable for applications in industrial electronics and automation, particularly where digital signals need to be transmitted, amplified, or distributed across multiple channels under low load conditions. Typical use cases include controlling small motors, lighting, sensors, or other electrical loads driven by a control device or PLC. Its compact design makes it especially suitable for enclosures with limited space.

Functions and Features in Detail
The RCM570R24 provides four changeover contacts (4 CO) made of AgNi alloy, ensuring high contact reliability and low contact resistance. The continuous current rating is 6 A, sufficient for most common low-load applications. The coil is rated for 24 V AC and consumes a nominal current of 45 mA with a coil power of 1080 mVA. The maximum switching capacity for resistive AC loads is 1500 VA, with an inrush current of up to 12 A (20 ms) during switching. The integrated red LED indicates the operating status, and the tactile test button allows for visual and functional testing of the relay without disconnecting power.

Technology Explained Simply
The AgNi contacts (silver-nickel alloy) are highly resistant to contamination and oxidation, increasing the relay’s lifespan and reliability. The 24-V-AC coil is a standard value in automation technology, as it is compatible with common control networks. The LED status indicator aids in troubleshooting by directly showing whether the coil is energized. The lockable test button allows testing the relay without power by briefly actuating it—useful during maintenance or commissioning.

Compatibility and Accessories
The relay is designed for plug-in mounting and can be installed in compatible relay sockets such as the SCM-I 4CO P (Push-In spring connection) or SCM-I 4CO (screw connection). Additionally, retaining clips (SCM-I CLIP M, SCM-I CLIP P) are available to secure the relay in the socket. For visual signaling, LED protection modules (RIM-I 3 6/24VUC) or LED modules (RIM-I 3 6/24VUC GN) can be combined. Device markers such as ESG 6/17 MM WS or ESG 6/15 MM WS, along with cross-connectors (SCM-I QV S), support structured installation and labeling.

Mounting and Installation
The relay is inserted into a compatible relay socket via plug-in connection. Installation is performed in enclosures or on printed circuit boards, with dimensions of 29 × 22.5 × 28 mm and a weight of 30.7 g enabling easy placement. The lockable test button and use of retaining clips ensure secure fixation in the socket. Connections are made via the contacts in the socket, with the type of connection (screw or spring) depending on the chosen socket.

Operational Advantages
The combination of compact design, high contact reliability due to AgNi contacts, and the integrated LED indicator provides a reliable and low-maintenance solution. The easy testability via the tactile test button reduces troubleshooting time. Compatibility with various sockets and accessories enables flexible integration into existing systems. Compliance with standards IEC 61810-1 and UL 508 ensures safety and reliability in industrial applications.
