A 4 to 20mA signal isolator that requires no external power supply. The power for the isolator is derived from the input loop. Typically the MIN310 could be used to provide a second isolated 4 to 20mA from an existing isolated loop. This would then allow two non-isolated inputs (e.g. an RTU input and a local indicator input) to monitor the same 4 to 20mA loop. If the input loop was not isolated you would need to use either a BM320 (24 Volt DC powered) or a BD320 (230/115 Volt AC powered) dual output isolator.
