Description
2 digital inputsSink connection3-wire connections2 counter inputs with 50 kHz counter frequencyGate measurement24 VDC and GND for sensor supplySoftware 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.
