## **INTRODUCTION** 

The SEM1605TC is a DIN rail mounted temperature transmitter from Status Instruments. It has been designed to accept most common thermocouple sensor inputs and provide the user with a standard two wire (4 to 20) mA output signal. Galvanic isolation is provided between input and output and all temperature ranges are linear to temperature. 

Designed for ease of use, our latest USB interface is fitted for quick and easy configuration. Just connect a standard USB cable between the SEM1605TC and your PC. Our free configuration software will guide you through any changes you wish to make. To further help save time, the SEM1605TC does not need to be wired to a power supply during the configuration process, it is powered via the USB interface from your PC. 

## > **FEATURE HIGHLIGHTS** 

**ACTIVE RANGE** The SEM1605TC is provided with a user push-button ranging option, allowing adjustments at both 4 mA and 20 mA for a live value. 

The ‘user adjust’ function can be locked during configuration if not required. The state LED indicates out of range input during normal operation, during ‘user adjust’ it is also used to indicate the stage of adjustment. 

**SENSOR REFERENCING** The SEM1605TC sensor referencing via the Windows based USBSpeedlink software allows for close matching to a known reference sensor, eliminating possible sensor errors. 

**SENSOR BURN OUT DETECTION** If a sensor wire is broken or becomes disconnected, the SEM1605TC output will automatically go to its user-defined level (upscale or downscale) or a pre-set value. 

**STABILITY** The SEM1605TC DIN rail transmitter incorporates the latest digital technology to ensure accurate low drift performance. 

**USB PC CONFIGURATION** The SEM1605TC is quick and easy to configure using a standard-type USB lead and the free-of-charge USBSpeedLink Windows software. 

**USB ANDROID VIEW** The SEM1605TC can be connected to an android phone or tablet using an OTG USB adaptor. Running a free App, the Android device can then be used to view live data from the SEM1605TC.
