The module supports 32-channel digital input. It supports sink input with high-level signals recognized as valid (compatible with PNP sensors), and also supports source input with low-level signals recognized as valid (compatible with NPN sensors).

The module can collect digital output signals from field equipment (dry contact or active output).

The module can be connected to 2-wire or 3-wire digital sensors.

The internal bus and field inputs of the module are isolated by optocouplers.

The module supports an input signal holding function, and the holding time can be configured.

The counting function is enabled after adding the counting sub-module in the ODOT configuration software.

Each input channel of the module supports a 32-bit counter with a counting frequency of less than 200 Hz.

The digital signal input filter time and counter byte transmission sequence can be configured.

Each channel of the module supports independent configuration of counting mode and counting direction.
