What is the B&R X20DI2377?

2 digital inputs

Sink connection

3-wire connections

2 counter inputs with 50 kHz counter frequency

Gate measurement

24 VDC and GND for sensor supply

Software input filter can be configured for entire module

The module is equipped with two inputs for 3-wire connections. Both inputs can be configured as event counters. Gate measurement is only ever possible on one channel.

This module is designed for X20 6-pin terminal blocks. If needed (e.g. for logistical reasons), the 12-pin terminal block can also be used.
