WebOptocoupler CTR formula CTR is the important parameter used to measure performance of an optocoupler. It is defined as ratio of the output or collector current of the device (i.e. Ic) with the input current applied to LED coupling device. The above equation or formula is used for Optocoupler CTR calculation. WebIn this application, the optocoupler is used to detect the operation of the switch or another type of digital input signal. This is useful if the switch or signal being detected is within an electrically noisy environment. The output can be used to operate an external circuit, light or as an input to a PC or microprocessor.
