Product Description

The digital input module X20DI2371 is a compact and robust solution designed for industrial automation systems. It is produced by B & R Automation, a reputable manufacturer known for its high-quality industrial automation and control products. This module is well-suited for applications requiring reliable and efficient digital input processing in environments.

The X20DI2371 digital input module operates with a nominal voltage of 24 VDC and adheres to EN 61131-2 standards for Type 1 digital inputs. It accommodates an input voltage range of 24 VDC. The module operates with a standard input current of 3.75 mA when supplied with 24 VDC that ensures efficient power consumption. The model is designed with a sink input circuit, which means that the input device sinks current from the module when activated. The digital module includes both hardware and software input filtering along with a hardware filter time of 100 us and a configurable software filter with a default setting of 1 ms. The module uses 3-wire connections and has an input resistance of approximately 6.4 k?. The switching threshold is clearly defined, with a low threshold of < 5 VDC and a high threshold of > 15 VDC.

The X20DI2371 model features integrated sensor power supply capabilities, with a maximum power consumption of 12 W. It is equipped with short-circuit protection, allowing for a voltage drop of up to 2 VDC at 500 mA. The module's summation current is capped at 0.5 A, and it is fully short-circuit proof. For electrical isolation, the module provides channel isolation from the bus, though channels are not isolated from each other. The operating conditions are versatile, allowing for mounting in both horizontal and vertical orientations.
