English
The design of the module is suitable for controlling rooms, hotel rooms (lighting, heating, sockets, etc.) and other applications, where the combination of inputs and outputs can be utilized - in particular with the requirement to switch loads with a capacitive character: lighting circuits, socket circuits, etc.
The module contains 8 binary inputs for connecting switching contacts, 3 analogue inputs for connecting resistive sensors, 8 relay outputs and one voltage analogue output (0 ÷ 12 V). Individual re lay outputs can be manually locally controlled via the buttons on the module panel.
The module is fitted with relays designed to switch capacitive loads, 4x relays with a 16 A contact and 4 relays with a 10 A contact.
Powering the module
If you connect an external 24 V power supply to terminals A3 and A4, the powering will be automatically switched from the CIB to this external source. To switch the power supply, a higher voltage than 19.2 VDC must be brought to the A3 terminal.
If the module is powered from an external power supply (terminals A3, A4), the CIB line could be overloaded during a power failure (e. g. if there is a power outage in the 230 VAC grid as well as in the CIB power supply backup).The module in this configuration allows activation of the mode, which blocks (opens) the switched contacts during a power failure; it prevents overloading the line (the module power consumption decreases to 25mA).
