SEM1636 Signal Conditioner/Trip Amplifier

Brand: Status Instruments

The SEM1636 monitors a (4 to 20) mA loop and provides two independent change over trip contacts set to alarm 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 linearisation functions are provided.
