General features

Module M-IN-16s is a component of the Ampio system. Required voltage to power the module is 11 — 16V DC. The module is controlled via CAN bus.

The module has sixteen alarm inputs.

Alarm inputs

The module has bi-state inputs that go into an active state when they are shorted to ground, allowing for the connection of any devices with potential-free contact outputs or optocoupler outputs. Such devices may include, in particular, reed switches and other alarm devices.

Depending on the configuration, alarm inputs can work with devices with the following types of contacts:

  • normally closed contacts,
  • normally open contacts,
  • tamper-proof contacts:
    • EOL NC/NO,
    • 2EOL NC/NO

In addition to alarm applications, the inputs can be used as general purpose inputs 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.

Typical application

  • Connecting classic light switches or other devices with potential-free contact outputs;
  • integration with devices with potential-free relay outputs;
  • integration with devices with optocoupler outputs;


The module is designed for mounting on a 35mm DIN rail. The module’s width is 105mm, 6 spaces/modules in DB. In order to start the module, it must be connected to the CAN bus. The bus of the Ampio 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 two connectors with screw terminals. They allow for connecting sixteen signal lines to alarm inputs.

In the case of loads with low power consumption, in particular small alarm sensors, it is possible to use the AUX terminals located on the alarm inputs' connectors, in order to power the devices. These terminals have the same voltage as the module’s supply voltage. The current consumption of each device connected to the AUX terminals must not exceed 100mA.

Device status LEDs

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:

  • one regular flash every 1 sec. – CAN bus communication is working properly,
  • two regular flashes every 1 sec. – the module is not receiving information from other modules,
  • three regular flashes every 1 sec. – the module cannot send information to the CAN bus;


The module is programmed with the use of the Ampio Designer 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.
