TECHNICAL REFERENCE MANUAL
4.3.3. IOLITEi-1xSTG
IOLITEi-1xSTG is a single channel strain gauge amplifier with internal quarter, half and full-bridge
configurations. Low noise voltage and current source excitation are available with freely settable levels.
Input ranges span from 50V to 100mV. Data transferred over the EtherCAT to a PC running powerful and
easy to use.
