825 Spectrum

Cardinal’s 825 Spectrum is not an indicative weighing instrument, but instead an independent programmable industrial weighing computer. It features a full-color 640 x 480 pixel back-lit LCD touchscreen display and stainless steel enclosure commanding 64 MB of memory combined with massive connectivity via 4 bi-directional RS232 serial ports, 110/100 Base-T Ethernet port, 2 USB A host ports, and 1 USB B device port, there is no end to this indicator’s potential.

Up to 8 operators may be programmed for use. Other features include a time/date function, adjustable filtering, Gross, Tare, and Net conversion, QWERTY keypad and navigation keys, as well as 4 inputs and 4 outputs along with a DeviceNet/ICAN port.

The 825 Spectrum features 2 ColdFire® processors along with multiple weighing applications and communication routines pre-installed in its 64MB standard memory. There is plenty of space to even program your own application.

It comes with 10 available slots for up to 10 expansion cards. Up to 10 individual scales can be managed, resulting in 46 Load Cells with 14 maximum Load Cells per scale.

Using the 825 Spectrum, up to 10 individual weighing applications (ex. silo) can be simultaneously read, while the 10 weighing indications are displayed on its screen and the data is quickly transported via Ethernet (TCP/IP or EIP) to your network. You can also easily receive automatic email notifications to up to 3 different users per scale by determining the limits you wish to pay attention to.
