IPAQ C520 
HART Compatible Universal Dual-input 2-wire Transmitters
The IPAQ C520 transmitters are universal, isolated, dual-input temperature transmitters with additional voltage and resistance input. The IPAQ C520N is approved for Non-Incendive use in Ex-Zone 2. C520X/C520XS are Intrinsically Safe versions for use in Ex-Zone 0, 1 and 2.
The transmitters are compatible with the HART 6 protocol. Typical characteristics are the high accuracy, stability and reliability combined with a robust housing.
