Product Description
The PRG-1802 frequency isolated safety barrier enables the safe transmission of frequency signals generated by hazardous area instruments to the safe area output. The input uses a hysteresis comparison circuit with high anti-interference performance, while providing power to on-site instruments. This product requires independent power supply, with power supply, input, and output isolated.
