The I400 system has three main components: transmitters, a graphic terminal, and a coupler. The transmitters connect up to four load cells and transmit weight information over a CAN Open field bus. The graphic terminal displays scale channels, runs application software, and is available in rack or stainless steel models. Optional accessories include communication modules, digital I/O modules, and analog outputs. The coupler connects the system to non-CAN Open field buses like Profibus DP or DeviceNet. The I400 is certified for various weighing applications including multiple range and multi-increment scales for non-automatic weighing and catch weighing, check weighing, belt scales, and discontinuous totalizing.
