Core Information of X20DI6371
X20DI6371 is a 6-channel digital input module from B&R’s X20 product series, designed for
industrial automation systems. It supports 1-wire or 2-wire sink connections with 24 VDC input,
features configurable software input filters, and offers a coated variant (X20cDI6371) for harsh
environments. Compliant with multiple industrial certifications, it is ideal for discrete signal
acquisition from sensors, switches, and other field devices.
●Model Number: X20DI6371 (standard) / X20cDI6371 (coated)
●Product Series: B&R X20 I/O System
●Core Function: Acquires 6 independent digital input signals (24 VDC) via sink connection, supporting
both 1-wire and 2-wire configurations for seamless integration with industrial sensors.
●Key Features: Configurable software input filter (0–25 ms), short-circuit proof sensor power supply,
channel isolation from bus, and status LEDs for real-time monitoring.
●Application Scope: Industrial automation scenarios (e.g., process control, manufacturing equipment),
compatible with hazardous locations (Class I, Division 2 / Zone 2) and general industrial
environments; coated variant suits condensation or corrosive gas environments.
