Description
IT2000M Weighing Module Applications
IT2000M features integrated batching functionality with material flow and tolerance check and can be started and controlled over network / fieldbus. The integrated display and keyboard provide check of weight as well as scale calibration on site without auxiliary means. A separate panel mount display/keyboard unit is available as an option. Setup time is reduced by simple installation on DIN rail, connection of cables with pluggable screw terminals and clear-text prompts for the calibration with or without test weights.
Weighing Electronics
Integrated factory calibrated A/D converter to connect to one or several analog strain gauge load cells (overall impedance 87.5–4500 Ohm). Resolution 30,000 d, internal resolution 524,000 d, W&M approved resolution 10,000 d at a max. of 80 % preload, 0.33 μV/e, update rate 50–800 filtered weight values / sec. Calibration as single-range or multiple-range scale. Option to linearize the weight curve.
Operational Security
Power-fail-safe storage of data, password protection, switch to protect calibration data, modules can be replaced without new calibration (only for systems not subject to W&M approval). Internal W&M approved weight storage for the last 120,000 weighings. Integrated webserver for remote access via password for setup, backup and maintenance.
Data Words To PLC/Host System
- Scale status, gross and net weight
- Batch ready message, actual weight and optimized preact
- I/O status.
Data Words From PLC/Host System
- Set zero, Autotaring, Taring with a specified value
- Start batching with transmission of target weight, preact and tolerance (weigh-in or weigh-out mode)
- Discharging l Read digital input, set digital output.
Display And Operation
Clear text display with background lighting to indicate weight (6 digits, character height 15 mm / 0.6″) and scale status (e.g. scale tared / under zero / overload). Up to 3 additional display lines (20 characters each, character height 4 mm / 0.2″). Info-key to show fieldbus input / output data words. Additional function keys for zero setting, taring and configuration / calibration.
