The ESIT ECI-BA is a recipe-featured digital weighing controller designed for multi-ingredient batching and filling systems in food, chemical, pharmaceutical, and agricultural processing. It builds on the ECI platform with enhanced hardware, a 4.5″ graphics LCD, and capacitive touch keys for intuitive recipe management.

How does the recipe batching system work?

The ECI-BA controls up to 4 silos as standard, expandable to 16 silos for complex multi-ingredient formulations. Each of the 96 storable recipes defines target weights per ingredient with configurable fast-slow filling modes. Automatic in-flight compensation (shoot adjusting) corrects for material already in transit when the fill valve closes, while recipe tolerance monitoring flags out-of-spec batches in real time.

What measurement performance does the ECI-BA deliver?

A 24-bit Sigma-Delta A/D converter with over 8 million internal counts provides 0.5 µV/d input sensitivity and 0.0015% full-scale sensitivity. The proprietary gResolver adaptive FIR filter suppresses mechanical vibration effects, enabling stable weight readings at up to 1600 Hz measurement rate with 800 Hz data output. Zero and gain stability of 2 ppm/°C ensures consistent accuracy across temperature variations. The controller supports up to 10 load cells at 350 Ω or 32 at 1100 Ω with 10 VDC excitation.

What fieldbus and I/O options are available?

The base unit includes 8 relay outputs (2 A, 250 V) and an RS232 serial port, plus a USB port for reporting, firmware updates, backup/restore, and recipe file transfer. Optional expansion cards add EtherNet/IP, Profinet IO, Profibus DP, Modbus TCP, or additional RS232/RS485/RS422 interfaces. External RL4 or RL8 relay modules and the EsRöle connection card (8 digital inputs + 16 outputs) provide further I/O for complex batching lines.

How is the controller calibrated?

The built-in Calibration Doctor wizard provides step-by-step guided calibration with quality inspection feedback. Multiple calibration methods are supported — weights, mV input, digital value entry, factory default, or coefficient — and calibration data can be backed up to the main board for restoration after a fault. Calibration portability allows transferring verified calibration data between ECI-BA units, reducing downtime during controller replacement.
