The GIRA 2001 xx controller scanned by the C-IT-0504S input module

The GIRA 2001 push-button controller is equipped with two short-stroke push-buttons (with a 24 VAC/DC nominal power supply) and two LEDs (24 VDC, 1mA power supply). It can be connected to the embedded C-IT-0504S module, which should be placed in the flush-box under the controller, and the result is a complete controller on the CIB bus. There are also 3 more inputs available, e.g. for measuring the room temperature (in an adjacent frame by the Pt1000 temperature sensor – see Chap. 10.1.4) and the floor temperature.

Similarly the GIRA 2003 controller with six push-buttons can be connected to the C-IT-09008S module. A similar example is presented in the following chapter (the Jung controller).

Notes:

1. The analogue outputs of the C-IT-0504S module have a max. of 10 V, 3 mA on the output, so the LEDs on the controller excited by these outputs shine without any problems. The analogue outputs need to be controlled as binary - i.e. they work with the values of 0 % and 100 %.

2. The C-IT-0504S module is terminated with about 100 mm long wire, which should be connected directly into the GIRA controller connector (the colours of the wires and other details are given in the Chapter on the C-IT-0504S).
