    • 品牌11: TESEO
    • 描述: The OAM301 plug-in system receives analog signals through a fiber link with a frequency range of DC to 1MHz and a distance of 1 km
    • 品牌: TESEO

      TESEO's DC, low-frequency plug-in modules and remote appendages are optical fiber communication links for the transmission of analog signals (including DC) in harsh environments affected by electromagnetic interference, noise or high voltage. A plug-in system consisting of a two-channel basic module, mounted on the TESEO host, 1/2 bifilar cables for signal and control, 1/2 batteries for power supply, shielded transmitter, 1/2 battery charger.

      Each plug-in system maintains 2 independent light channels. It provides researchers and engineers with a complete technical solution to solve the function of safely monitoring the EUT in a strong electromagnetic field or high voltage environment.

      The frequency range of the OAM301 plug-in system receiving the analog signal through the optical fiber link is DC~1MHz and the distance is 1km. The OAM301P basic unit plug-in has two optical/electrical independent channel receivers, and you can connect 1/2 OAM301S auxiliary units to it. The MOCS-MF host can be inserted into 6 OAM301P basic unit plug-ins to provide a total of 12 independent optical channels. System configuration and status are displayed on the LCD graphic display of the host computer, and all functions can be used and managed through the MOCS keyboard or the embedded GPIB-RS232 interface. The OAM301 automatically performs a full calibration at startup in order to compensate for possible gain changes, such as connecting or disconnecting optical connectors. In addition, you can choose zero or reference level at the output port for calibration. Information about battery status is also available.

      The small size battery-operated OAM301S accessory unit can be placed close to signal monitoring points, or in hard-to-reach areas (eg engines, industrial equipment). It can be turned on or off from the host, and nine input ranges can be selected, from 1 Vpp to 500 Vpp full scale. The input impedance is 1M ohms and can be coupled with AC or DC signals. The signal source can be switched from the signal input to zero and reference levels, to perform calibration of test configurations or to check the remaining charge of the battery. OAM301S can withstand the electromagnetic field strength higher than 200 V/m, the frequency range is 10 kHz~18 GHz, and it works in a wide range of environments without major changes in performance. It can work continuously for more than 8 hours and can be charged with the accessory battery charger in a short time. The ruggedness of the appendage also makes it ideal for acquiring signals from remote sensors in extremely harsh environments.
