B&R Industrial Automation X20DI6553 Digital Input Module

The B&R X20DI6553 is a six-channel digital input module for the X20 I/O system that accepts 100–120 VAC, 47–63 Hz signals via 1-wire connections per channel. Each input has channel isolation from the bus and an isolation voltage of 1500 VAC for 1 minute, with a default input filter of 1 ms (configurable 0–25 ms in 0.2 ms steps). The module draws 0.21 W from the backplane bus, while external I/O power adds about 0.68 W; sensor power supply voltage follows the module supply. The device is rated IP20 and supports horizontal and vertical mounting, with operating temperature ranges of -25 to 60°C (horizontal) and -25 to 50°C (vertical), storage -40 to 85°C. It complies with CE, UKCA, UL/cULus E115267, cCSAus 244665, KC and ATEX Zone 2, II 3G Ex nA nC IIA T5 Gc IP20 (Ta per X20 user’s manual). The X20DI6553 provides 6 digital inputs using 1-wire connections, designed for use where stability and isolation of inputs from the bus are required in rugged industrial environments. Common applications include machine automation, sensor networks, and safety interlock or status signaling in 100–120 VAC control circuits.
