Digifeeder Controller Module
The Digifeeder Controller Module is a component in a rotary liquid metering system consisting of a Controller, Motor/Base and Pump Modules capable of repeatable flow rates ranging from microliters/minute to a maximum of 4-liters/minute. The Controller Module accepts analog input signals to proportionally change the flow rate. The input signal is converted to digital pulses that immediately and precisely control the stepper motor.


Features:

  • Solid state electronics
  • Digital control of Stepper Motor
  • Auto/Manual Switch
  • Slope Multiplier to select RPM range
  • Overrange Indicator
  • Minimal maintenance
  • Accepts analog control signal: 0-5V, 4-20mA
  • NEMA 4X enclosure available
  • Custom designs
  • Analog feedback available
  • CE Certificate available

This Controller Module used with the following modules:

Maintainer Controller Module
The Maintainer Controller Module is a component in a rotary liquid metering system consisting of a Controller, Motor/Base and Pump Modules providing automatic continuous set-point control of process variables in chemical or biological systems. The controller is easily programmed by the user and can be interfaced directly with a process instrument such as a pH meter, or other analog output process signal in order to provide set-point control. It is designed to provide a metering rate proportional to the process deviation from a set-point so overshoot is virtually eliminated and process stability is greatly enhanced.

Features:

  • Solid state electronics
  • Digital control of Stepper Motor
  • Minimal maintenance
  • System Response Factor (SRF) multiplier switch
  • Auto/Manual switch
  • Direct/Inverse switch
  • Slope Multiplier to select RPM range
  • NEMA 4X enclosure available
  • Set-point control of process variables
  • Accepts analog control signal: 4-20mA
  • CE Certificate available

This Controller Module used with the following modules:

OX Controller Module
The OX Controller Module is a component in a rotary liquid metering system consisting of a Controller, Motor/Base and Pump Modules. The OX controller is time based and flow rates are adjusted manually with a digital selector switch. This controller can be enabled via manual or remote control, and can interface with PLC systems. The OX is capable of repeatable flows rates ranging from microliters/minute to a maximum of 4-liters/minute.

Features:

  • Enabled via manual or remote control
  • Solid state electronics
  • Selectable flow rate control
  • Digital control of Stepper Motor
  • NEMA 4X enclosure available
  • Minimal maintenance
  • Custom designs
  • Feedback signal available
  • CE Certificate available

This Controller Module used with the following modules:

Replenisher Controller Module
The Replenisher Controller Module is a component in a rotary liquid metering system consisting of a Controller, Motor/Base and Pump Modules. This control module is specifically designed to provide precise continuous additions of electroplating bath materials as they are depleted. The rate of replenishment is based upon a control signal obtained from the output of an ammeter shunt or process controller. These units can be scaled for replenishment rates as low as 0.001ml/ampere-minute up to 9.99ml/ampere-minute and higher. The Replenisher allows the user to continuously replace materials as they are being depleted from the plating bath to improve process quality.

Features:

  • Replenishment rates between 0.001ml/ampere-minute and 9.99ml/ampere-minute.
  • Digital control of Stepper Motor
  • Replenishment Rate Pushwheel to select RPM range
  • Solid state electronics
  • Minimal maintenance
  • Overange indicator
  • NEMA 4X enclosure available
  • 0 ­ 50 mV input terminal block
  • Custom designs
  • CE Certificate available
