The CATAN DOI8 UOI8 UI8 extension module is housed in a compact DIN rail-mounted housing with an overall width of just 6 HP. It expands a Catan controller by 8 universal inputs, 8 universal outputs, and 8 digital outputs, which can alternatively be used for the digital input or counter function. The universal inputs are suitable for temperature sensors, 0 V ... 10 V interfaces, or as counters, among other things. The universal outputs can be used as 0 V ... 10 V interfaces, for example for controlling valves and fans.
