Page 16: Function Description
Function Description Digital inputs DI2 The module PSS(1) DI2O Z has 16 DI2 type inputs (I0 ... I15). Input signals must show a “High” of 24 VDC (+15 ... +30 VDC) or a “Low” of 0 VDC (-3 ... +5 VDC). The inputs have a filter and are galvanically isolated from the control electronics through optocouplers and converters. - Page 17 Function Description Diagnostic circuitry checks the function of the outputs. On outputs that are switched on, the CPU will alternately switch off the “+” and “-” terminals as part of each cycle. This is to check that the corresponding output transistors can be switched off and that there is no interruption to the load.
