2. Functions and Application Scenarios
Signal Isolation and Amplification: As an intermediate relay, the core function of RM602024 is to achieve signal isolation and contact expansion in the control circuit. It is suitable for scenarios such as industrial automation and power equipment control, for example, the amplification of PLC output signals or multi-loop control.

Typical applications:
Industrial drive system: RM602024 connects sensors and actuators to achieve logic signal conversion.
Power system: It is extended as an auxiliary contact in the distribution cabinet to support motor control or protection circuits.
Special environment: It has the ability to resist vibration and shock, and is suitable for high-interference or harsh environments (such as factory workshops).
3. Alternative Solutions and Compatibility
TE Connectivity alternative models: If direct replacement is required, alternative models of the same series RM602024 (such as RM602024N) can be considered, or contact TE officially to obtain compatible solutions.
ABB Product line recommendation:
CR-MX series: Plug-in intermediate relay, supporting 24V DC/230V AC coil voltage, contact capacity 7-10A, with indicator light design, compliant with ROHS[dt_divider style=”thin” /] standard.
R600 series: Boxed intermediate relay, suitable for high-vibration environments, offers multiple coil voltage options (such as 24V DC, 230V AC), and the contact capacity can reach 16A.
CR-S series: Ultra-thin design (width only 17.5mm), supports high-density installation, and is suitable for control cabinets with limited space.
4. Precautions
Discontinued production and Inventory: RM602024 has been discontinued. Market inventory is limited.

Summary
RM602024 is actually an intermediate relay of TE Connectivity and has been discontinued. It is recommended to consider the CR-MX, R600 or CR-S series. These models are more in line with ABB’s industrial control solutions in terms of voltage compatibility, contact capacity and environmental adaptability. Before making a purchase, be sure to confirm the correctness of the model and confirm it with the supplier.
