SCM-W-HRT7 is a SCM series HART revision 7 communication module. The SCM series of SolaHD communication module provides network connectivity support for one or two SDN-D series power supplies over popular industrial protocols. The SCM-W-HRT7 model provides wired HART protocol support and is fully HART certified. SCM-W-HRT7 is compatible with SDN1024100D version xx 06 10, SDN2024100D version xx 05 16 SolaHD SDN-D power supplies. As a HART compliant device, it is designed to work with Emerson's DeltaV™, AMS Device Manager and TREX and other HART hosts. Since the SCM generates minimal heat itself, the internal temperature of the SCM should be a good proxy for ambient temperature.
