Weight Transmitter AST-S-II-CHECK

Weight Transmitter AST-S-II-CHECK

A dedicated, compact weight transmitter/weighing indicator for DIN rail panel mounting. Ideal for dynamic and/or high-speed robotic weighing systems.
Thanks to its algorithm and high conversion speed, the transmitter calculates the weight of a package moving across a weighing belt and stores the data in a memory that can be accessed via the Fieldbus. Designed for a throughput of over 200 units per minute.

Available in the following versions

• RS485, type AST-S-II-X-CHECK
  With specific program for dynamic weighing, suitable for high-speed applications.
• PROFINET I/O, type AST-S-II-PRONET-X-CHECK
  With specific program for dynamic weighing, suitable for high-speed applications. Complete with PROFINET communication port.
• ETHERNET IP, type AST-S-II-ETHIP-X-CHECK
  With specific program for dynamic weighing, suitable for high-speed applications. Complete with ETHERNET IP communication port.
• MODBUS TCP, type AST-S-II-MODTCP-X-CHECK
  With specific program for dynamic weighing, suitable for high-speed applications. Complete with MODBUS TCP communication port.
• ETHERCAT, type AST-S-II-ECHCAT-X-CHECK
  With specific program for dynamic weighing, suitable for high-speed applications. Complete with EtherCAT communication port.

MAIN FUNCTIONS

• Dynamic weight sampling at high speed, up to 4800 Hz
• Automatic weighing detection
• Weighing start/stop by weight tresholds or by triggers (digital inputs/photocells)
• Memory for the last 10 weighings
• Fully programmable weight filters using the free XSPEED TOOL
• Load cell failure detection

Integrated web server (for PROFINET, ETHERNET/IP and MODBUS TCP/IP models).

• The integrated web server enables full remote diagnostics, calibration, data backup and configuration of the weight transmitter via an Ethernet network.

Xspeed tool

• XSPEED Tool is the free PC program for optimizing the performance of the weighing system integrated in the process and industrial automation. Through XSPEED TOOL, you can set the most suitable weighing filter for your application and create custom filters, thus maximizing the speed and accuracy of weighing in static and dynamic applications.
