FlexSmart TRMS Module (2 channels) w/modular plug Sensor

Part # S-FS-TRMSA-D
 
 

Overview

The 15-bit two-channel FlexSmart True RMS Current / Voltage 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.

NOTE: If using the S‐FS‐TRMSA‐D with a U30‐GSM or RX3003-00-01, the S‐FS‐TRMSA‐D should be located approximately 1 meter (3 ft) from the U30 in order to avoid interference from the U30's GSM radio. Use Smart Sensor extension cable Onset part # S‐EXT‐M002.

Highlighted Features

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