Product information MR8905 - Input module for MR8875
The MR8905 Analog Unit is a 2-channel voltage input module for the memory recorder MR8875. It enables voltage measurement of instantaneous values and AC RMS values.
Each channel supports measurement ranges from 500 mV to 50 V/div. The module uses 16-bit A/D conversion and supports simultaneous sampling across both channels at up to 500 kS/s. The frequency characteristics extend from DC to 100 kHz (–3 dB).
The module supports RMS measurement with defined accuracy and response time. Input coupling modes DC, AC-RMS, and GND are selectable.
The maximum allowable input voltage is 1000 V DC or 700 V AC. The maximum rated voltage to earth is CAT II 1000 V AC/DC and CAT III 600 V AC/DC.
Typical applications include voltage measurement, RMS evaluation, and waveform analysis in laboratory and industrial environments.
