The SEM1000 series of loop powered DIN rail analogue signal isolators is claimed to set new standards when it comes to cost and space effectiveness.

The SEM1000 series of loop powered DIN rail analogue signal isolators from Status Instruments is claimed to set new standards when it comes to cost and space effectiveness, making them ideal for both OEM and retrofit applications.

The compact nature of the devices means that many more units can be installed in existing cabinets, while their high accuracy permits the addition of isolation to systems without significantly degrading the overall system performance.

If necessary the span and zero potentiometers can be used to remove any system errors.

The SEM1010 isolator is typically used to provide isolation between a field mounted, two wire 4-20mA transmitter and a PLC type device with a common power supply.

The required supply for the two wire transmitter is obtained from the power supply connected to the output terminals of the 1010 and total isolation is maintained between these and the transmitter.

The SEM1200 signal splitter is a low cost isolator that provides two isolated 4-20mA outputs from a single 4-20mA input.
