Function: LB5105A

The thermocouple converter accepts thermocouple or mV signals from hazardous area.

Open circuit line fault alarms are detected.

The intrinsically safe inputs are galvanically isolated from the bus and the power supply (EN 60079-11). There is a functional isolation between the channels.
