The module is designed to supply power for controlled heating and for the measurements of the precipitation detector S-RS-01I, also for heating and measurements of the 24 V rated voltage icing sensors (mainly products of the V-system company), see Chapters xxx, including switching the defrosting cables.It is also possible to connect 2 probes for level measurement to the module, e.g. for monitoring water level limits in the tank. The inputs and outputs can be used as general AI/DI and DO.
The module contains 5 analogue inputs, of which 3 are designated for connecting resistive sensors, or as standard digital inputs; 2 analogue inputs are designed for AC resistance measurement in sensors for icing, precipitation and point level probes.
Furthermore, the module is fitted with a PWM output DO4 intended for supplying and controlling heating of the sensors. The output is only intended to power these sensors with a power input about 2 W; the output circuits have no overload protection.
The C-IS-0504M module is also equipped with 3 relay outputs, 1 x 16 A and 2 x 5 A, e.g. for switching heating cables for defrosting, and the like.
Individual re lay outputs can be manually locally controlled via the buttons on the module panel.

The relay outputs of the C-IS-0504M module:
The DO1, a separate output, switching contact,
continuous current in the output is 16 A, short-time overload 80 A (max. 20 ms), more detailed information on the relay contacts
isolation voltage from the other circuits and outputs is 3,750 VAC,
i.e. safe isolation of circuits.
The DO2, DO3, outputs with a common terminal, switching contact,
continuous switching current 5 A, more detailed information on the relay contacts
The parameters of the connectors used are listed in Chap. 13.3.1
The module is in a 3M box.

Notes:
-
The D04 output is designed solely for the heating of sensors with the power up to 2 W, 24 VDC.
-
The AI4 and AI5 inputs measure the resistance using AC voltage of approx. 3.3 V; the input is intended solely for the measurement of conductivity sensors and probes - it is not designed to measure temperature or other parameters.
