Easily configure true RMA measurements with two channels

A 15-bit two-channel module accepts an input range of 5mV to 512mV and is compatible with 333mV FS output sensors. Field wiring is 2-wire via screw terminals.

The S-FS-TRMSA is easy-to-configure, True-RMS input measurement modules. The S-FS-TRMSA is compatible with HOBO® H22 series data loggers. The 2-channel modules has an input range of 512 millivolts RMS full-scale and is fully compatible with industry-standard voltage and current transformers (PT and CT) which output 333 millivolts RMS full-scale.

The modules feature extremely low-power operation, resulting in long battery life for unattended data logging applications.

Features

• 2 input channels of AC Current and/or Voltage
• Measures True RMS for accurate readings of sinusoidal and non-sinusoidal waveforms
