SMART (4 to 20) mA LOOP POWERED DUAL TRIP AMPLIFIER SEM1636 DUAL TRIP OUTPUT WITH INDEPENDENT SET ACTIONS POWERED FROM (4 to 20) mA LOOP VOLTAGE BURDEN 5 VOLTS TRIP RATING 250V AC 1A 30V DC 1A NORMAL AND INVERTED LOW/HIGH/DEVIATION TRIP ACTIONS OPTIONAL FILTER AND USER LINEARISATION FUNCTIONS LED TRIP INDICATION, FAIL ON OR FAIL OFF TRIP ACTIONS CONFIGURATION USING USB PORT INTRODUCTION The SEM1636 monitors a (4 to 20) mA loop and provides two independent change over trip contacts set to trip at any point within the (4 to 20) mA range. The SEM1636 requires no additional power connection as power is derived from the (4 to 20) mA loop. Trip outputs are independently configured for action and set point, dead band. Six actions are provided normal High/Low/Deviation and inverted High/Low/Deviation. Additional math, filter and user linearisation functions are provided. Designed for ease of use, our USB interface is fitted for quick and easy configuration. Just connect a standard USB cable between the SEM1636 and your PC. Using our free configuration software, the user can configure the device to the required application. To further help save time, the SEM1636 does not need to be wired to a power supply during the configuration process, it is powered via the USB interface from your PC.
