Simplify Multi-Sensor Load Cell Installations with Accurate Signal Summing
The FUTEK IAC200 is a compact, industrial-grade 2–4 channel summing junction box. Designed for applications that require the combined output of multiple full-bridge strain gauge load cells. Ideal for platforms, weighing systems, and multi-point force measurement setups. It enables you to connect multiple sensors to a single display or DAQ system with ease.
This summing junction box aggregates signals from up to four mV/V input sensors, providing either a raw (non-amplified) or conditioned analog output (VDC or 4–20 mA), depending on the model selected.
✅ Key Features
2–4 Channel Signal Summing: DIP switch-selectable channels allow flexible sensor configuration.
Available Output Types:
mV/V (non-amplified)
0–5 VDC, ±5 VDC, 0–10 VDC, ±10 VDC (voltage output models)
4–20 mA (current output models)
Individual Span Adjustments: Fine-tune sensor signals for 350Ω, 700Ω, or 1000Ω bridges.
Robust Housing: IP65 / NEMA 4X rated UV-stable polycarbonate enclosure for outdoor or harsh environments.
Easy Installation:
Screw terminal blocks
Cable strain relief supports diameters from 2.0 mm to 6.35 mm
Flange mounting with dual mounting holes
