| - | {{ :modport:md-daout2b:md-daout2b.png?700 }} | + | The MD-DAOUT2B is a 2-channel digital to analog current, 0~20mA / 4~20mA , output module. The current range is configured using the dipswitch on the side of the module |
| + | |||
| + | The MD-DAOUT2B’s negative terminal controls the current through a connected load; so it should not be | ||
| + | connected to a fixed potential. The MD-DAOUT2B should be used to drive differential loads. To drive single-ended loads, an isolation circuit may be required. | ||
