The SEM1636 monitors a (4 to 20) mA loop and provides two independent change over relay 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. Relay 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 linearization functions are provided.  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.  Visit the software page to download the USB Speed-Link software.
