It has been designed to accept most common process and temperature sensor inputs and provide the user with a dual relay output. Isolation is provided on all three ports. 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 SEM1630 and your PC. Using our free configuration software, your PC will automatically upload the existing configuration data and guide you through any changes you wish to make. ## **FEATURE HIGHLIGHTS** **TEMPERATURE SENSOR BURN-OUT DETECTION** If a temperature sensor wire is broken or becomes disconnected, the SEM1630 relays will automatically trip and the LED illuminate. **STABILITY** The SEM1630 DIN rail trip amplifier incorporates the latest digital technology to ensure accurate, low-drift performance. **FRONT PANEL LED INDICATION** The state LED indicates out of range input during normal operation. LEDs are provided for each relay and will illuminate in alarm condition. “On” if the relay is in an alarm condition. **USB CONFIGURATION** The SEM1630 is quick and easy to set up using a standard type USB lead and the free-of-charge configuration software. **USB PC CONFIGURATION** The SEM1630 is quick and easy to configure using a standard-type USB lead and the free-of-charge USBSpeedLink Windows software. **USB ANDROID VIEW** The SEM1630 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 SEM1630 **INPUT SPECIFICATIONS @20°C Pt100** D2446-01-11 CN5710 SEM1630 Data Sheet, Page 1 of 4 SEM1630 UNIVERSAL DIN RAIL TRIP AMPLIFIER |**Type/Function**|**Range/Description**|**Accuracy/Stability**| |---|---|---| |Pt100 3 wire|
