Voltage-to-Current Isolator Provides High Accuracy

1B21 Provides 1,500-VRMS Isolation in a Small Package at Low Cost; Device Has Programmable 4-20 mA and 0-20 mA Ranges

The 1B21 voltage-to-current (V/I) converter provides isolation to ±1,500 V rms in a small, low-cost package using surface-mount technology. It is intended to protect the signal source in process-control applications that require electrical isolation between the source, e.g., programmable-controller output, and the load (typically a valve or actuator) controlled by this source. Read full article
