The image above is for illustration purpose only. The actual module may vary from the one presented here.
Module M-INOC-4p is a component of the Ampio Smart Home system. Required voltage to power the module is 11 — 16V DC. The module is controlled via CAN bus.
The module has four ground-detecting inputs, four OC outputs, and a 1-Wire interface. It also supports the functionality of the RGBW lighting controller.
The module has open-collector outputs allowing for smooth control of resistive loads supplied with voltage of up to 24V DC. It is also allowed to control loads of moderate inductive nature, in particular relays. Control is performed by the method of pulse-width modulation (PWM). Internally, each of the outputs allows the connected line to be short-circuited to the module’s ground.
As part of the module’s configuration, it is possible to activate the functionality of the RGBW lighting controller. Nominally, each of the open-collector outputs is controlled independently. When the functionality is activated, the control is done by defining the colour and intensity of the light.
The module has inputs that go into the active state when they are shorted to ground. They can be used in the case of any devices with potential-free contact outputs, e.g. wall switches, reed switches, buttons, switches, etc. They can also be used for integration with devices with potential-free relay outputs or optocoupler outputs with a collector voltage greater than 12V.
The module is equipped with a 1-Wire interface connector that allows to connect up to 6 digital Dallas DS18B20 temperature sensors. The temperature measurement result is available for all devices operating within the building automation bus. It may turn out to be particularly useful for purposes related to temperature regulation, or to present the measurement result on touch panels and in a mobile application.
The total length of the 1-Wire bus cable to which the temperature sensors are connected cannot exceed 15m.
The dimensions of the module enable its installation in a standard junction box. In order to start the module, it must be connected to the CAN bus. The bus of the Ampio Smart Home system consists of four wires - two for power and two for communication between the modules.
In addition to the CAN bus interface, the device has three connectors with screw terminals. They allow for the connection of four signal lines to ground-detecting inputs, four resistive loads to open-collector outputs, and up to 6 digital Dallas DS18B20 temperature sensors.
When using the open-collector outputs functionality, it should be borne in mind that the supply circuits of the connected loads are closed by the mass of the module. Therefore, it should be ensured that the mass of the device is connected to the mass of the power supply with a cable of appropriate thickness.
On the front of the module there are signalling LED indicators. The green LED with the label CAN indicates the status of communication on the CAN bus:
The module is programmed with a special programmer, available for authorised technicians, and the Ampio Smart Home CAN conﬁgurator software. It allows you to modify the parameters of the module and define its behaviour in response to signals directly available to the module as well as general information coming from all devices present in the home automation bus.
