Installation04/07 AWB8230-1541GBTerminal AM supplies an analog reference signal from 0 to +10 V(default = 0 to 50 Hz). The reference potential is terminal L. Theanalog signal can be configured with parameters PNU B080, C028and C086.+24 VF 100 mACM2 1112AM0...+10 VF 1 mAFigure 50:Example with external power supplyL0 VhUse relays that switch reliably at 24 V H and a current ofabout 3 mA.Figure 48:Example: analog measuring instrumentIf a relay is connected to one of the digital outputs 11 or 12,connect a freewheel diode in parallel to the relay to preventdestruction of the digital outputs through the self-induced e.m.f.which results when the relay is switched off.The two digital outputs 11 and 12 contain optically decoupledopen-collector transistors. Up to 50 mA can be applied to each ofthem. Their <strong>com</strong>mon reference potential is terminal CM2 (max.100 mA).Internal diode matrix R1 to R4 allows the connection in sink-typeor source-type logic (a fig. 51). Sink-type logic is the preferredconnection method in Japan and the USA. Source-type logic ispreferred in Europe, a figure 49 and 50.LP24 CM2 1112+24 VF 100 mAFigure 49:Relay with freewheeling diode (for example ETS-VS3)+24 V+24 VCM2R3R1R3K111R1K1R4R2R4K111CM211R2CM20 VSink type logic0 VSource type logicFigure 51:Digital outputs48
