¹⁾ This is the maximum power consumption of the SITRANS SL

²⁾ These are the maximum input values

³⁾ These are the maximum output values

⁴⁾ Note:
"Normal operation" stands for normal operation of the analyzer. The system is connected to the voltage source and is running without problems; no error message generated or displayed.
"Normal under power" refers to the status of the relay under the above-named normal operation. The relay contact of the alarm signal is closed.

⁵⁾ We recommend that the Ethernet connection is not made via the cable to the Ethernet terminals in the detector unit. Instead, the Ethernet connection should be made via the sensor cable connection set which is optionally available for the detector unit.
