The Siemens 3RK2400-1BT30-0AA3 is a robust and compact AS-i module designed for digital input and output operations in demanding industrial environments. This module is part of the K20 series and is housed in an IP67-rated enclosure, ensuring protection against dust and water ingress, making it suitable for field operations. It features two digital inputs and two digital outputs, supporting PNP transistor input circuitry and offering a flexible connection for both 2- and 3-wire sensors.
The module operates with an input voltage range of 16.5 to 30 V and is capable of handling sensor supply currents of up to 150 mA at 40°C ambient temperature, ensuring reliable performance even in varied temperature conditions. The digital outputs can supply a maximum of 1 A, with an external power supply of 24 V DC, shared via a round cable connection with the AS-Interface connection through an M12 female connector.
Designed with ease of use in mind, the Siemens 3RK2400-1BT30-0AA3 allows for straightforward addressing using an M12 female connector and features built-in polarity reversal protection. The module's compact dimensions and the absence of a need for a mounting plate facilitate easy integration into existing systems. Additionally, the module is equipped with LED indicators for I/O status, auxiliary voltage, and AS-Interface diagnostics, providing clear and immediate visual feedback on the operational status.
This AS-i compact module is a reliable choice for engineers and technicians looking for a high-quality, durable solution for their digital I/O needs in industrial automation applications.
