Intrinsically safe relay isolation amplifiers – intrinsically safe NAMUR transducers or binary signal isolators are the basic type of intrinsically safe interface designed to protect electrical circuits placed in an explosion hazard environment. They contain electronic components ensuring mutual galvanic separation of input, output and power supply circuits. They are mainly used as optoisolators, safety relays and elements with magnetic coupling, all in a special design in accordance with the ČSN EN 60079 standard. The input (or output) circuits to which the cables leading to the potentially explosive environment are connected are additionally equipped with protective blocks with diodes (including Zener diodes), combined with fuses and resistors. Diodes limit the voltage fed to the intrinsically safe circuit, and failure-free resistors limit the maximum current flowing through the circuit. Intrinsically safe insulators are used as an interface between intrinsically safe circuits and circuits that are not intrinsically safe. They are produced both for isolation of binary and analog circuits, or only as sources of intrinsically safe energy without the possibility of transmitting signals.
