Loadcell Module
The Loadcell Module is a GOcontroll Moduline-compatible expansion card that interfaces directly with load cells and strain-gauge sensors. It provides sensor excitation and per-channel analog-to-digital conversion with selectable gain, turning force, weight or pressure measurements into accurate digital values for the Moduline controller.
Like every Moduline module, it plugs straight into a controller expansion slot and is configured through the GOcontroll platform.
Applications
- Weighing and on-board weight measurement
- Batch weighing and dosing systems
- Silo, tank and hopper content monitoring
- Crane, hoist and lifting load monitoring
- Overload and safe working load protection
- Force and press-force measurement
- Torque measurement
- Tension and compression monitoring
- Pressure measurement with strain-gauge sensors
- Axle and vehicle load measurement
Features
- Four differential load cell inputs for resistive strain-gauge (Wheatstone) bridges
- Two common sensor excitation voltage lines (EXC 1 / EXC 2)
- Analog-to-digital conversion with selectable gain per channel (32, 64 or 128)
- Selectable sample rate per channel (10 or 80 Hz)
- Selectable sensitivity mode per channel (raw, 1, 2 or 3 mV/V)
- Per-channel tare (zero-point) function
- Four channels, each independently configurable
- GOcontroll Moduline compatible (S1, M1, L4 and HMI1)
