RF615:
RF615 may be a model or series name, but no specific search results provide details. Typically, models beginning with RF may be Radio frequency-related modules that may be used for wireless communication or data transmission.
If the RF615 is an ABB product, it may have features related to wireless communication or remote monitoring.
RC610:

The ABB RC610 is a digital input module that receives a digital signal, such as the status of a sensor or switch, and converts it into a digital signal that the control system can process.
The module may have multiple input channels to accommodate different input requirements and may have electrical isolation to improve the safety and reliability of the system.
The RC610 module may support a variety of communication protocols, enabling it to communicate with different control systems or devices.
