One of the features of Atom series controllers are multifunctional input ports:
● digital● digital with optocoupler● analog● interface (1-wire)
List of currently available devices when configuring inputs:
● Light sensor - analogue device (photoresistor)● Button - key without position locking (doorbell type)● Switch - a traditional switch with 2 fixed positio● Motion sensor - a typical device used in security systems. As a rule, it has a "normally closed" output● Door / window opening sensor - magnetic contact (reed switch). As a rule - "normally closed"● Leak sensor - a water detector on the surface. There are models in the form of 2 contacts (analogue), or with the built-in scheme of detection and indication of a condition● Smoke detector - a device for fire detection. As a rule, it has a "normally closed" output● Temperature sensor - analogue sensors (thermistors) NTC, Pt100, Pt500, Pt1000● 1-wire bus (for connecting DS18B20 digital temperature sensors)

Multifunctional inputs in Atom series controllers (3U and 6U) have two operating modes that can be selected by jumpers:● Direct connection, commonly used with devices with digital interfaces (1-Wire) and devices with analogue output (temperature and light sensors)● With optocoupler (3U and 6U only), it is usually used to connect devices with dry contact output: switches, buttons, motion sensors, leak detection sensors and others. This mode is not available for 9U controllers, so all devices are connected in direct connection mode
