Isolated safety barrier

The frequency input is safety barrier (one input and one output), which converts the frequency pulse signal in the dangerous area into 4 ~ 20mA current signal through isolation and outputs it to the safe area. This product requires independent power supply, three-terminal isolation of input, output and power supply, and has the function of on-line fault self-diagnosis, the measurement range and output signal type of the frequency pulse signal can be configured by PC or handheld programmer.
