The FIX-IV is a very compact dual-channel measurement module for 12 V, 24 V and 48 V systems. Sensor and Data Processing electronics are permanently mounted on an internal precision shunt with connection lugs for direct installation in the current path — no probe, no adapter, no cable between sensor and module. Very short analogue signal paths and fully digital processing deliver excellent signal quality; the module is factory calibrated as one unit and starts measuring as soon as power is applied. Fewer connectors significantly shorten installation time.
