X20DI9371 Advantages
The B&R X20DI9371 Digital Input Module stands out from comparable digital input modules in several key areas.
12‑channel high‑density sink‑type digital inputs. The B&R X20DI9371 Digital Input Module acquires switch status from proximity sensors, limit switches, push‑buttons and other field devices simultaneously. This capability is critical for machinery interlock logic and status feedback collection for auxiliary industrial equipment.
Multi‑level configurable input filtering. Combined hardware filter and adjustable software filter suppress contact bounce and high‑frequency field electromagnetic noise. Users can set filter parameters according to on‑site interference conditions to obtain stable input readings.
Per‑channel LED status indication and module diagnostic feedback. The B&R X20DI9371 Digital Input Module shows each channel’s on‑off state via front‑panel LED indicators. Module operating and fault status can be uploaded to the X20 CPU over X2X‑Link bus for convenient on‑site inspection and remote equipment diagnosis.
1‑wire sink‑input design. This wiring scheme matches most standard European‑style 24 VDC field sensors, simplifies cabinet wiring work and reduces installation workload.
Wide operating temperature range. The B&R X20DI9371 Digital Input Module performs reliably under variable cabinet thermal conditions for both horizontal and vertical DIN‑rail mounting orientations. No additional cooling or heating protection is required.
Native X20 System integration. As a factory‑original B&R component, the B&R X20DI9371 Digital Input Module directly mates with compatible X20 terminal blocks and X2X‑Link bus hardware. No extra adapters or custom modification are required.
