Their P600 series weight controller, shown above, is a single board version of their larger P700 series system. Even though this system is smaller it’s only smaller in the the number of I/O - 8 optically isolated digital inputs, 4 optically isolated mains outputs. The rest of the board has the same processing power, memory size and loadcell channel as the larger double system. There is also 1 serial port - either RS232 or RS485.

2 features not available on the larger system is a solid state pulse output for totalising pulses and a 2x 4-20mA or 0-10V analog output ports.

This system has a weighing software for serial links to printers and Modbus protocol to link to SCADA packages or PLC’s or variable speed drives. Their in-house developed W7Linker program supports this unit.

Enclosure options are open to various weighing applications. Their standard enclosure is a 3mm thick Stainless Steel unit with lockable front lid.

Customised Control weight controller P700 shown below, consists of a top board which has the memory, CPU, power supply, communications ports, keyboard and display ports. The second board which plugs under the top board is the I/O board having a single loadcell channel, 16 optically isolated digital inputs and 8 optically isolated mains outputs.

The bottom I/O boards can be cascaded up to 4 I/O boards per top CPU board. This makes for a very versatile, powerful and expandable controller.

This weighing system has software for serial links to printers and Modbus protocol to link to SCADA packages, PLC’s or variable speed drives. Their in-house developed W7Linker program supports this unit.

Below are examples of the two boards that make up their P700 series weight controller. Enclosure options are open to various applications. Their standard enclosure is a 3mm thick Stainless Steel unit with lockable front lid.
