B&R X20DI4371 Digital Input Module | 16-Ch IP65 Isolated DI with EtherCAT & 0.2ms Response

Description

The B&R X20DI4371 is a rugged digital input module designed for industrial automation applications, featuring 16 isolated digital input channels and an IP65 rating for reliable operation in harsh environments. It supports EtherCAT communication with a fast 0.2ms typical response time, with configurable filter time options ranging from 25 microseconds to 100ms, including default 3ms settings, to adapt to high-interference industrial sites and reduce false triggers. The module uses X2X Link bus for communication, syncing data update cycles with the bus cycle down to 1ms to meet real-time control requirements.

Electrical specifications include a typical 24VDC input voltage with an allowable range of 15-30VDC to accommodate industrial power fluctuations, and per-channel typical on-state input current of 3mA, with a maximum of 5mA. It uses PNP-type inputs (high-level active, compatible with NPN sensors via external circuit conversion) and supports both dry contact (passive switch) and wet contact (active signal) inputs. The module draws power via the X20 series backplane bus, with a total power consumption of approximately 2.5W when all 16 channels are active. Additional features include flexible wiring options, programmable configuration, and built-in diagnostic functions to monitor channel status for issues like short circuits or open circuits, enhancing operational reliability.
