The digital input interface TDS12117 has 16 input channels for all kinds of voltage free contacts, to be used as inputs to the system. The contacts can be from standard wall mounted push buttons, motion and presence sensors, door and window contacts, contact from burglar and fire alarm systems, rain sensors, etc.

Additionally, the digital input interface is able to receive pulse counter inputs. This is used to measure inputs from energy meters, to measure electrical power consumption or production (PV panels), gas, water, precipitation, wind speed, etc…

This is an AUTOBUS connected interface with power over AUTOBUS like almost every TELETASK interface.
