Information. For Multidrop HART installations, remove 'HART Link' and connect HART
systems directly to IC2: this allows the analog output function to be retained.

3.4.5 Current Output – Fig. 3.20 and 3.21
Information.
• Output is fully programmable – see Programming Guide.
• Output is electrically separated from all other MagMaster connections.
• External isolators are not normally required and may significantly limit accuracy if used.
