SEM1020 Loop Booster

Brand: Status Instruments

The SEM1020 Isolator is designed for use when power is available at both sides of the isolation barrier.

This isolator requires no user adjustment during commissioning, apart from an initial test, to ensure it operates correctly over its full working range.

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.
Features
  • Provides Extra Drive Capability From An Existing Current Loop
  • Only Requires 2.7 V From The Existing Loop
  • Galvanic Isolation
