A Q45 Emitter/Receiver detects when someone steps on the first step and sends a discrete signal to the Gateway to turn the light on. The light switch has a built-in timer that turns the light off after 20 minutes.
Create point-to-multi point networks that distribute I/O over large areas. Input and output types include discrete (dry contact, PNP/NPN), analog (0 to 10 V dc, 0 to 20 mA), temperature (thermocouple and RTD), and pulse counter.
