GCU 64

GCU 64 The new weighing terminal GCU 64 (with 64-bit micro-processor) has been designed for static and dynamic weighing applications and is also available in a legal-for-trade version. Beyond ist standard functions, the terminal can be used for complex control and regulation tasks.

For this purpose, it needs to be equipped with additional interfaces and digital or analog inputs and outputs. The programmes are modified by WÖHWA software engineers to adapt to individual customers’ requests.

For safe and simple operation, the terminal is equipped with a clearly laid out and robust plastic-foil keypad and a full graphics LCD display. Integration into processing systems via PROFIBUS interface. The terminal offers a multitude of expansion possibilities allowing you to remain flexible for all your applications.

The WÖHWA weighing terminal may be upgraded at any time for the control of peripheral devices such as remote displays, barriers, traffic lights, frequency converters, etc.

The terminal can be equipped with a maximum of 7 serial interfaces RS232 or RS422/485 (optionally 2 of which may be TTY current loop interfaces), 2 CENTRONICS printer interfaces, 32 digital inputs or outputs 0-10 V or 0-20 mA / 4-20 mA.

Additionally, a PROFIBUS interface can be integrated. A PC keyboard may be attached for easier and faster data input.

  • plastic desktop housing with plastic-foil keypad
  • protection class IP54
  • LC graphics display
  • compatible with previous models
