Have more control over your desired discharge rate than ever before with our improved pulse and analog signals.

・Signal Output Function

-You can output signals to external equipment

Unit Pulse Output: A fixed amount is discharged everytime a pulse signal is output.

Alarm Output: An alarm sounds when an error occurs.

Motion Output: A signal is output while the pump is operating.

・Pulse Input Proportional Operation

-It is possible to automatically operate the pump by inputting a pulse signal from outside equipment.

-This functional allows you to control the volume and length of time a predetermined amount of liquid will be discharged at. For example, if you wanting to discharge 100mL of liquid, you can set the pump to discharge the solution at a rate of 50mL/min over 2 minutes, 25mL/min over 4 minutes, and so on every time the pump receives a pulse. (Refer to Figure #1)

・Analog Input Proportional Operation

-It is possible to automatically change the flow rate in proportion to the analog signal input (4-20 mA) from outside equipment.

-Example 1) Flow rate control from 0-50 mL/min using a 4-20 mA signal.

-Example 2) Flow rate control from 100-0 mL/min using a 4-12 mA signal. (Refer to Figure #2)
