The DI-10 provides 16 input points in one group with common power for field contacts. The inputs are designed for wide ranging DC and AC input signals from external devices. Input characteristics are compatible with a wide range of user-supplied input devices, such as: push buttons, limit switches and electronic proximity switches.

The DI-10 module provides all the functionality of the DI-1 and DI-5 modules except the field voltage polarity cannot be reversed. It has software configurable debounce filters, channel inversion and Sequence-of-Events recording selectable on any channel(s). Frequency, pulse or quadrature counting can also be configured for any 7 input channels.

The first 4 channels are high speed inputs, capable of counting up to 10 kHz; the other 12 inputs can count up to 1 kHz. The DI-10 module has 7 user-configurable counter inputs, which appear as 16-bit unsigned integer values in the analog input registers.
