UNIVERSAL DIN RAIL TRANSMITTER SEM1620 SIMPLE CONFIGURATION VIA USB PORT UNIVERSAL PT100, THERMOCOUPLE, mV, mA Input ISOLATED INPUT PUSH BUTTON USER TRIM THREE WIRE ISOLATED VOLTAGE OUTPUT INTRODUCTION The SEM1620 is the next generation DIN rail mounted temperature amplifier from Status Instruments. It has been designed to accept most common process and temperature sensor inputs and provide the user with a three wire voltage output signal. 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 SEM1620 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. To further help save time, the SEM1620 does not need to be wired to a power supply during the configuration process, it is powered via the USB interface from your PC. The following parameters are configurable :- INPUT TYPE LOW RANGE HIGH RANGE UNITS OUTPUT TEMPERATURE USER TRIM PROBE BURNOUT PT100 F, C (0 to 10) V (2 to 10) V T/C K, J, E, N, T, R, S F, C Up/Scale Low input High input (0 to 5) V On , Off Down/Scale value for low value for high (1 to 5) V output value output value (0 to 1) V mV mV mA mA The SEM1620 is also provided with user push button adjust, allowing adjustments at both offset and span. 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 used to also indicate the stage of adjustment.
