Product Description:

The S20-AIAO-2 is a precision module. It is available for use with S-type load cells, delivering repeatable and accurate force measurement for industrial load and weight monitoring applications. It is intended to be used with load cells producing analog output in terms of millivolts per volt (mV/V) and has a rated capacity of 2 kN, ideal for mid-range load sensing in machines, material handling equipment, or structural test equipment.

The module is intended to receive excitation voltage of 5 to 15 V DC, offering compatibility with most standard strain gauge-based load cells and ensuring stable and repeatable excitation under fluctuating loads. With non-linearity of ±0.03% of full scale (FS), this module delivers high accuracy in measurement. It sustains precision as it reaches the capacity of the load cell. It also has hysteresis and creep characteristics rated at ±0.03% FS. This delivers repeatable results and long-term stability under sustained load conditions. Output resistance is specified at 350 ± 5 ohms, in accordance with typical load cell configurations. It enables simple integration with existing measurement systems. This module is built in rugged form to survive harsh mechanical environments. It comes with a 150% FS safe overload capacity and 300% FS ultimate overload capacity. This offers protection against sudden load spikes or abuse. This comprehensive overload protection prolongs the life of the mounted load cell and safeguards the system against costly damage. The S20-AIAO-2 module is well adapted to applications where reliability in force feedback is critical, for instance, in packaging machines, press control, or industrial automation systems that demand accurate load monitoring.

By offering a stable analog interface and a durable mechanical support, the module offers precision and protection in applications where load variation and stability are critical. Its compact size and stable performance make it a trusted component in contemporary force measurement systems.
