Function

This isolated barrier is used for intrinsic safety applications.

Each device channel works as a transmitter power supply or a current driver.

The device transfers data by using a current signal.

The device supports a bi-directional communication for SMART devices that use current modulation to transmit data and voltage modulation to receive data.

For current driver operation, an open field circuit presents a high impedance to the control side to allow lead breakage to be monitored by control systems.
