520R Series

HART® and SIL 2 Compatible Universal Dual-input Rail Mounted Temperature Transmitter

The 520R Series is a universal, isolated, dual-input rail mounted temperature transmitter with additional voltage and resistance input. The 520R is approved for Non-Incendive use in Ex-Zone 2 and is Intrinsically Safe for use in Ex-Zone 0, 1 and 2. The transmitter is compatible with the HART® 6 protocol and SIL 2 according to IEC 61508-2.

Typical characteristics are high accuracy, stability and reliability combined with a robust housing.
