IO42E01KNX is an input and outputs interface device and can be configured with ETS® to communicate with the KNX Data Secure protocol.
Module includes:
• 2 digital inputs
• 1 analog / digital input
• 1 digital / analog / smart sensor input
• 2 relay output (bistable)

Digital inputs are intended to be connected to free potential contacts and can interface sensors, traditional buttons, etc; they can be used to on/off commands, dimming, shutter control, scene recall and control, sequences of 3 objects.
Inputs 3 and 4 can be configured as analogue for the connection of NTC temperature probes (see eelectron probes code TS01A01ACC / TS01B01ACC/ TS01D01ACC) with which to send the temperature measurement on the bus or manage a complete thermostat module. The thermostat manages 2 stages with an integrated PI controller for controlling heating and cooling equipment, valves, 2 and 4-pipe fan coils.
Input 4 can be configured as “smart sensor” for connection of the plug-in sensors: SM03E01ACC that includes a di temperature sensor (range from -5°C to +50°C) and a CO2 sensor (range from 10 ppm to 1000 ppm) and SM03E02ACC that includes a temperature sensor (range from -5°C to +50°C) and a VOC sensor for measuring Indoor Air Quality (IAQ) and CO2 equivalent (eCO2).

Device 2 outputs on board can be configured:
• Each output can be configured independently for load control (2 independent channels).
• Outputs can be configured in pairs for the management of roller shutters and blinds; (1 channel).
• For controlling a servomotor, in pairs.
• For logic interlock control.

The device integrates an antenna with BEACON BLE (Bluetooth Low Energy) function. Data format compatible with iBeacon® and Eddystone®.
The device allows you to set the transmission frequency and signal strength.
BLE technology allows the sending of messages to mobile devices. These devices must have an app that allows them to receive information from BLE beacons.

Moreover, 12 logic blocks are available to implement simple expressions with logical or threshold operator or complex expressions with algebraic and conditional operators; It is possible to use predefined algorithms as proportional controls of temperature and humidity or dew point calculation.
The device also integrates the “Virtual Holder Logic”; the field of application is
the hotel room: through a magnetic sensor installed on the door and connected
to a digital input, accurate presence information is managed. The presence detection solution can deduce the presence of people in the room using one or more dedicated sensors. It also detects an unexpected presence and is able to differentiate more behaviors.
