Product description

WP-8000-EX series detection terminal isolated safety barrier (HART) provides isolated power supply voltage for the two-wire smart transmitter connected to the dangerous site, and isolates and converts the (4-20) mA signal generated by the transmitter Then it is transmitted to the safe zone control system or other intelligent instruments.

   The product supports two-way communication with HART digital signals. Also compatible with non-smart transmitters.

   This isolated safety barrier requires independent power supply, electromagnetic isolation between the power supply-input circuit-output circuit.
