- Combines two 24 VDC sink inputs with two 50 kilohertz event counters
- Supports gate-time measurement on either input, one measurement channel at a time
- Provides short-circuit-protected 24 VDC and GND connections for sensor supply
X20DI2377 is a B&R digital input and counter module designed for X20 System I/O stations.
It integrates the documented I/O channels, electrical behavior, diagnostics, and model-specific functions into a compact X20 station slice.
Before installation or replacement, verify the complete material number, sink or source topology, terminal and bus modules, field supply, wiring, software configuration, and installed-system requirements.
Availability, condition, price, and shipping time for X20DI2377 are confirmed during quotation.

- Both digital inputs can operate as 16-bit event counters
- Positive input edges are evaluated at frequencies up to 50 kilohertz
- The counter values are transferred cyclically through the X20 system
- Gate-time measurement can use input 1 or input 2 but only one channel at a time
- The documented minimum pulse length is 20 microseconds
- The documented minimum pause between pulses is 100 microseconds
- ATEX Zone 2 approval: II 3G Ex nA nC IIA T5 Gc, IP20, subject to the X20 user's manual requirements
- cCSAus certification covers Class I, Division 2, Groups A, B, C, and D hazardous locations with a T5 temperature code
- Documented marine approvals include DNV, CCS, Lloyd's Register, Korean Register, ABS, and Bureau Veritas
- High-speed event counting from 24 VDC pulse sensors in X20 control systems
- Gate-time measurement for pulse-width or timing acquisition on one selected channel
