The SEM1200 is a current loop splitter that provides two isolated (4 to 20) mA passive outputs from a single passive (4 to 20) mA input. The output loops must be powered externally. It is housed in a 12.5mm wide DIN rail mount plastic enclosure with screw terminals for wiring.
- Provides 2 isolated (4 to 20) mA outputs from 1 (4 to 20) mA input
- Galvanic Isolation
- High Accuracy & High Reliability
- 12.5mm wide
Why use a loop isolator? Many low cost transmitters do not have built in isolation, and can expose your PLC to voltage in the event of a component failure, The SEM1200 is a simple way to add isolation to temperature or power measurement 4-20mA transmitters, used with a PLC. Useful in HVAC systems, refrigeration systems, chillers, environmental monitoring, computer room monitoring, dryers, compressors, and other applications.
This ground loop isolator requires no user adjustment during commissioning. Minor adjustments can be made to the calibration of the device by means of the two front panel accessible calibration potentiometers. Incorrect connection in the loop will not damage the device as long as the specified maximum currents/voltages are not exceeded.
