The digital input module DI 169 from Sigmatek is used to count flow rates. Applications for the S-DIAS module include for example, to monitor energy usage of electricity, water, gas or heat volumes. The DI 169 has a so-called S0 interface, over which all commercial energy meters can be connected.

On only 12.5 x 104 x 72 mm (W x H x D), 16 digital counter inputs are integrated for open collector outputs. This enables fast pulse counting (count frequency up to 1 kHz). The channels can be used optionally as ground switching inputs or event counters.

When used as a counter input, three modes are available to choose from: normal mode, single and four-edge evaluation. In the standard counter mode (16 channels), a separate direction - forwards or backwards - can be selected. With a single edge analysis, the counter counts up or down with each rising signal edge. With the four-edge evaluation, the falling edge is also recorded. For the single and 4-edge analysis, 2 inputs are combined for one channel. The count direction can be configured in the software. The 8-bit counter can be used to count up or down. In the process map, it is expanded to a 32-bit counter
