Input and output properties Binary inputs – voltage levels DI/AI, the requirements for the switching circuit The AI/DI universal inputs on the CFox and RFox modules (this does not apply to DI modules C (R)-HM-1113M and C(R)-HM-1121M), which will be used as D1... Input and output properties Binary inputs – a reliable assessment of short pulses The CFox and RFox modules (DI) digital inputs provide a reliable assessment even of a short switching. A short pulse T1 is extended, so that for at least... Input and output properties Parameters of analogue and binary inputs of CFox, RFox modules The following chapter provides detailed technical information for an informed decision on the suitability and connection of inputs and outputs of the Foxtrot... Installation, securing Principles of application of shielded cables The shielding of the external and internal cables of the control panel should always be connected to the main protective earth (with grounded frame... Installation, securing Interference suppression, application of interference suppression elements If the system controls power elements with inductive character (valves, contactors, larger relays, smaller motors, etc.), you should always ensure the... Installation, securing Installation and laying cables Cables with digital signals should be laid out of direct contact with the cables for analogue measurement and communication lines (the recommended distance... Installation, securing Protection of the output elements (relays, etc.) The most active element of the systems are still classic electromechanical relays with unprotected contacts. In addition to the standard resistive loads...
