Product Description

Product Description

<1>. NPEXA-G11 safety barrier transmits thermocouple signals from hazardous area to safe area by isolating transmitting current or voltage signals,and automatically makes temperature compensation for cold end.

<2>. The input, output, and power supply are galvanically isolated from each other.

<3>. This safety barrier is an intelligent product with online self-diagnosis function.

<4>. Customer may set the type and the range of the input or output signals with a handheld programmer we provide.
