The Yokogawa 760813 Current Input Module is a direct current input converter designed for the PX8000 Precision Power Scope, transforming analog current signals into high-resolution digital data for precision power measurement and industrial monitoring applications. Operating at 12-bit resolution with up to 100 MS/s sampling, it accepts current inputs from 10 mA to 5 Arms and delivers ±0.1% accuracy across the 45 Hz to 1 kHz band. The module supports DC to 10 MHz bandwidth for direct current measurement and achieves superior common-mode voltage rejection at 1000 Vrms, making it suitable for demanding measurement environments.

– Compatibility & Integration
Primary integration platform is the Yokogawa PX8000 Precision Power Scope. The 760813 requires mandatory pairing with the 760811 Voltage Module to enable power measurement capability. Firmware updates may be necessary for existing PX8000 systems. Compatible with auxiliary modules including the 760851 for sensor signal processing (torque, rotation speed) and standard Yokogawa current probes across multiple current ranges.
