INTRODUCTION
The SEM1801/2XTC Din rail temperature transmitter accepts thermocouple temperature sensors and converts the
sensor output over a configured range to a standard industrial (4 to 20) mA transmission signal. Two versions are
available; single or dual channel ATEX / IECEx approved for hazardous areas.
PC configuration allows the user to select TC type, Range, Filter, units, linearization and Burnout direction, without
requiring calibration equipment. Additionally, the user may read live process data when connected to the PC (in the
safe area), this allows for sensor offset, and output alignment calibration, where the user can enter values to match
the actual process and therefore reducing system errors.
If required, the desired range can be specified at the time of order, removing the need for user configuration.
If the range is not specified then the transmitter will be shipped with the default range of (0 to 1000) °C type K.

For gas applications, the SEM1801XTC, SEM1802XTC temperature transmitters must be mounted in a metallic enclosure rated for IP54 and located in area where
the enclosure will not be subject to impact of friction.
For dust applications, the SEM1801XTC, SEM1802XTC temperature transmitters must be mounted in a suitably ATEX or IECEx certified enclosure appropriate for
the zone of end use .
The equipment shall only be configured by means of the USB connection outside the hazardous area.
If the equipment is mounted in an enclosure with separate IS circuits, appropriate segregation shall be provided in accordance with IEC 60079-11 Clause 6.2.1.
SEM1801XTC, SEM1802XTC - Only for connection to suitable thermocouples. These shall conform to the requirements for simple apparatus as defined in IEC
The ambient temperature range of the enclosure will limit the permitted ambient range of the overall equipment. Refer to enclosure certification.
