Do you have a question about the Siemens AS-Interface 3RK2402-2 00 Series and is the answer not in the manual?

This manual describes a range of AS-Interface modules, including digital and analog variants, designed for industrial automation applications. These modules serve as an interface between field devices and the AS-Interface bus system, enabling efficient data exchange and control.

Function Description

The AS-Interface modules facilitate the connection of various sensors and actuators to the AS-Interface network. Digital modules are used for binary signals, such as those from pushbuttons, limit switches, or indicator lights, while analog modules handle continuous signals, like those from temperature sensors or pressure transducers.

The modules are designed for easy integration into existing AS-Interface systems. They acquire input signals from connected field devices and transmit them to the AS-Interface master. Conversely, they receive output commands from the master and actuate connected devices. This bidirectional communication allows for centralized control and monitoring of a distributed I/O system.

Specific module types offer different functionalities:

3RK2200-0C.00-2AA2 / 3RK2200-2C.00-2AA2: These appear to be digital input/output modules, likely offering multiple digital inputs and outputs for connecting a variety of binary field devices. The pinout suggests connections for DI3, DI2, DI1, and DIO, along with corresponding positive and negative terminals.
3RK2402-2C.00-2AA2 / 3RK2402-2M.00-2AA2: These modules also seem to be digital I/O types, possibly with additional features or different channel configurations, indicated by the 'M' in the part number for the -2M.00 variant, which might imply a different form factor or specific functionality.
3RK2100-1C.00-2AA2 / 3RK1400-2C.00-2AA2 / 3RK2400-2C.00-2AA2: These modules are likely digital I/O units, with the pinout showing similar DI and DO connections. The different series numbers (2100, 1400, 2400) suggest variations in channel count, current capabilities, or specific application focus.
3RK1207-0C.00-2AA2 / 3RK1207-3C.00-2AA2: These are analog modules, indicated by the "AI" (Analog Input) and "AO" (Analog Output) designations in their pinout. They support multiple analog input channels (AI0+, AI1+, AI2+, AI3+) and potentially analog output channels, allowing for the connection of sensors and actuators that provide or require continuous signals. The "IC" (Input Current) and "L" (Load) designations further clarify their analog capabilities.
3RK1107-0B.00-2AA2: This module appears to be a digital I/O module with specific AS-Interface addressing (AQ0-I, M0-I, AQ1-I, M1-I) and power connections (AQ0-U, M0-U).

All modules communicate over the AS-Interface bus, which provides both power and data on a single two-wire cable. This simplifies wiring and reduces installation costs. The modules are designed to be robust and suitable for industrial environments.

Important Technical Specifications
