Hardware DescriptionElectrical specificationTable 1-14Electrical specification of the digital inputsDigital Inputs Minimum Typical Maximum NominalVoltage at high signal level (U H) 15 V 1) 30 V 24 VInput current I IN at U H 3.7 mA – 7.5 mA –Voltage at low signal level (U L) –30 V – +5 V 0 VSignal delay T PHL , T 2) PLH – 3 s – – 1) see Table 1-13 (Page 1-23) 2) The PROFIBUS communication time and the application cycle time must alsobe taken into account. A polarity reversal does not cause a high signal level nor does it destroy the inputs.Connecting cablesThe required connecting cables must be provided by the user: Supply voltage X6-2, Pin 1 (P24OUT), external supply voltage P24OUText:Wire, conductor cross section 1.5 mm 2 (AWG16) Digital inputs X6-2, Pin 2 to 11:Wire, conductor cross section 0.5 to 1.5 mm 2 (AWG20 – AWG16)General electrical propertiesGalvanic isolation using optocouplersActive current limitation of inputsProtection from negative input voltageMeasuring inputADI4 only supports measuring on the positive or negative measuring input edge. Aparameterization for the simultaneous measuring on the positive and negativeedges is not supported.1.2.9 Interface (H1/H2): Module statusThe module status is displayed on the front of the module with four diagnosticLEDs.Table 1-15Diagnostic LEDs (H1/H2)Designation Color DescriptionH1 POWER Green Supply VoltageOVTEMP Red Overtemperature indicationH2 EXCHANGE Green Cyclic data exchange with the DP master is in progressREADY Red Ready for cyclic data exchange with the DP master1-24 Siemens AG, 2003.
