Wall push-buttons scanned by the input module C-IT-0504S

The built-in C-IT-0504S module can be used in a similar way as the C-IT-0200S; it can scan e.g. 4 push-buttons of the controller, measure the interior temperature, and it can also control up to 4 LEDs, if the controller is equipped with them.

The module is equipped with 5 inputs, which can be configured (together for 4 inputs and the fifth separately) as analogue (connecting the temperature sensors, such as the Pt1000), or binary (connecting the push buttons, balanced inputs). It is also equipped with 4 analogue outputs 0 ÷ 10 V, max. 3 mA per output (for powering the LEDs of the controllers, for lighting and heating control).

Notes:

1. The example illustrates a possible module configuration as 4 + 1 (4 contact inputs, the fifth is analogue - the reversed combination is also possible, or all inputs can be binary or analogue).

2. The analogue outputs can be utilized e.g. for controlling the lighting ballasts, etc.
