The 140CRA21120 model from Schneider Electric is specifically designed as a DIO drop interface. This component incorporates two redundant ports to ensure reliable data transmission. It has a rated supply voltage set at 24 V DC, allowing for operation within a range of 20 to 30 V DC. With a maximum supply current capacity of 1.6 A, the interface can accommodate demanding requirements.

Inrush current capability is significant at 30 A when supplied at 24 V, providing ample power to overcome load fluctuations. Additionally, the output voltage is measured at 5.1 V, with a nominal output current rating of 3 A, ensuring effective handling of connected devices. Its minimum load current is zero, allowing versatility in different applications.

Safety features are integrated into the design, including both short-circuit protection and output overvoltage protection to mitigate potential risks during operation. The device is rated for a buffer time of up to 1 ms, which aids in response times for connected systems. An associated fuse rating of 2.5 A protects against overload conditions.

Power dissipation is accounted for with a rating of 11 W, sufficient for maintaining operational efficiency. Finally, the device connects through a seven-pole terminal block, allowing for straightforward wiring and connectivity.
