Foxtrot basic modules System power supply – power sources The Foxtrot system and the CIB buses are powered by 24 VDC or 27.2 VDC (in case of a battery backup). Tolerance limits of supply voltage are given in Chapter... Foxtrot basic modules FOXTROT – the basic and peripheral modules, power supply The Foxtrot basic module is an independent control system equipped with power circuits, communication channels, inputs and outputs.The development tools... Installation, securing Protection of electrical wiring, the characteristics of a modular circuit breaker Tab 1. Tripping characteristics in accordance with the ČSN EN 60898 standard: Tripping characteristics B short-circuit... Input and output properties The analogue inputs – the resolution and the measurement accuracy of the temperature sensors Individual temperature sensors differ not just in the temperature measurement range, but above all in their sensitivity and characteristics. This also... Input and output properties Double balanced inputs - the voltage levels, evaluation By using two resistance values, the idle state and the activation of the detector are transmitted. The idle state is determined by the basic value of resistance,... Input and output properties Single balanced inputs – voltage levels, evaluation Connection of a single-balanced loop (input) is shown in the following diagram. The ALARM contacts (the output is open on the detector activation) and... 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...
