(4 to 20) mA LOOP BOOSTER

SEM1020

	10 Year Warranty
	12.5 mm wide
	High Accuracy
	Galvanic Isolation
	High Reliability

The SEM1020 is a cost effective isolator requiring power supply connections on both the input and output terminals.

If true isolation is to be maintained, the two power supplies used must be fully isolated from each other.

The most common use for the SEM1020 is to provide extra drive capabilities from an existing (4 to 20) mA current loop.

The input circuitry only drops 2.7 V from the existing current loop and providing a 24 V isolated power supply is used on the output side, the isolator will drive up to 900 ohms.
