CPX Modular Electrical Terminal - FESTO - #201

Text version of the page

Terminal CPX Technical data - Pneumatic interface MPA Function The pneumatic interface MPA establishes the electromechanical connection between the CPX terminal and the valve terminal MPA. The signals from the bus node are forwarded to the control electronics in the electrical modules of the valve ter­minal MPA via the integrated CPX bus. The bus signal for activation of the solenoid coils is converted in the electronics module for max. 8 coils. From a technical point of view, the individual MPA pneumatic modules each representa separate electrical module with digital outputs. Valves, which are galvanically isolated, can be supplied with power via the interlinkingblock CPX-GE-EV-V. Applications • Interfaceto the valveterminal MPA • Max. 128 solenoid coils • Features of the electronics module ofthe valve terminal MPAcan be parameterised, for example status ofthe solenoid coils in the event offieldbus communication being interrupted (fail-safe), individual channel diagnostics can be acti-vated, condition monitoringcan be activated individually for each valve • The pneumatic interface receives the voltage for the electronics and the supply voltage for the valves from the left-hand interlinking block and feeds them through to the electronics modules of the valve terminal MPA • Electronics modules of the valve terminal MPA: - Undervoltage of valves - Short circuit of valves -Open load of valves - Counter preset reached in condition monitoring General technical data Type VMPA-FB-EPL-G VMPA-FB-EPL-E No. of solenoid coils 128 Pilot air supply Internal External Pilot air connection 12/14 - M7 Pneumatic connection 1 GVi GVi Operating pressure [bar] 3...8 -0.9 ...10 Pilot pressure [bar] 3...8 3...8 Nominal operating voltage [VDC] 24 Protection classto EN 60529 IP65 Ambienttemperature [°C] -5 ...+50 Materials Cover Polyamide Housing Die-cast aluminium Weight [g] Approx. 320 2011/06 - Subject to change Internet: www.festo.com/catalog/... 201
