Introduction This Sensor FG-R05-3A is a high-sensitivity DC/AC Current Sensor that can detect leakage Current of DC and AC. If DC fault occurs, PIN 4 will change state from low level to high impedance. If AC fault occurs, PIN5 will change state form low level to high impedance. This Sensor has a test coil for testing the operation of the Sensor, and by inputting a signal from the outside it is possible to pass a test Current to the test coil. It also outputs a digital signal informing that leakage Current of DC/AC has been detected.
Features ● for IC-CPD to the standard IEC 62752:2016 ● UL2231(CCID20) ● Open-loop, Flux-gate type Current Sensor ● PCB mounting ● Digital output of fault detection
General description the 74HC193; 74HCT193 is a 4-bit synchronous binary up/down counter. Separate up/down clocks, CPU and CPD respectively, simplify operation. the outputs change state synchronously with the LOW-to-HIGH transition of either clock input. If the CPU clock is pulsed while CPD is held HIGH, the device will count up. If the CPD clock is pulsed while CPU is held HIGH, the device will count down. Only one clock input can be held HIGH at any time to guarantee predictable behaviour.
