Complementary equipment

The terminal box S-G05 is easy to handle and at the same time versatile applicable accessory for micro annular gear pumps. The terminal box allows control of the pump with a potentiometer. As an alternative the pump can be remotely controlled with an external analog voltage signal 0–10 V, an external current signal (0–20 mA or 4–20 mA) or with a RS-232 interface. To set all operating parameters including calibration, ramp, step, speed, dispense/pause times and flow direction an adapted software with a serial interface RS-232 is delivered. The CE-conform installation includes an EMC module. The terminal box and micro annular gear pump can be provided optionally with an external 24 V DC power supply.
