Output Signal

Analog output

Two-way, fully isolated 0~10mA/4~20mA

Load resistance: 0 ~ 1.5kΩ when 0 ~ 10mA; 0 ~ 750Ω when 4 ~ 20mA

Frequency output

Forward and reverse flow output, the upper limit of output frequency can be set within 1 ~ 5000Hz. Open collector bidirectional output of transistor with photoelectric isolation. The external power supply is not greater than 35V, and the maximum current of the collector when conducting is 50mA.

Alarm Output

Two open-collector alarm outputs with photoelectric isolation transistors. The external power supply is not greater than 35V, and the maximum current of the collector when it is turned on is 250mA. Alarm status: fluid empty pipe, excitation disconnection, flow overrun.

Pulse output

Forward and reverse flow output, the upper limit of output pulse can reach 5000CP / S. The pulse equivalent is 0.0001 ~ 1.0m³ / P. The pulse width is automatically set to 20ms or square wave. Open collector output of transistor with photoelectric isolation. External power supply is not greater than 35V, the maximum current of the collector when conducting is 50mA
