27 2TLC172001M0211_A5 Connection of inputs5.1 Dynamic signalsThe IQ terminals can be configured as dynamic outputs, and be used for voltage supply of theinput devices. If they are configured as dynamic, each of them generates a unique pulse trainas shown in the diagram below.The system is intended for detection of different short circuits in external cabling, and dynamicmonitoring of sensors. It enables the connections of devices such as “SPOT” light beams,EDEN sensors etc. that inverts the input signal.In the software a configuration of the inputs must be made to decide which kind of input signaleach input shall accept as logic ”1”. Other signals that do not match with the configured signalare regarded as ”0”.5.1.1 Connection of inputs, I..Input type I_ can be connected to; A, B, C, A-inverse, B-inverse, C-inverse or +24V.The diagram below shows possible connections and how they are configured in the software.NOTE: The connections are only to show how devices can be electrically connected and arenot to be taken as connections for any specific applications.Dyn A, B or CI_I_I_IQ_ Configured as dynamic outputI_I_I_Example of software declaration:!
