-{{ :modport:md-daout2b:md-daout2b.png }}
+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.

+| Isolation Method         | No Isolation                                         |
+===== Output Current =====
+Values between 0 ~ 60,000 correspond linearly to the output current (4 ~ 20mA, dipswitch OFF / 0 ~ 20mA,
+dipswitch ON).

+===== Modbus Starting Address =====
+Each module has 2 channels, each with its own unique Modbus address.
+^Channel ^0 ^1 ^
+|Starting Address(base 10) | 3400 | 3401 |
+|Starting Address(base 16) | CE4 | CE5 |
+|Address (base 10) used by HMI (SCADA) | 43401 | 43402 |
+===== Module ID (Modbus Slave Address) Assignment =====
+On the front of the module, there is a rotary switch labeled //ID//, that is used to select the Modbus slave address for the module. When installing multiple modules of the same type, the ID for each module should be unique.
+Rotary switch position 0 corresponds to Modbus slave address 10. If the ID is changed after the module is powered on, it must be power cycled for the new ID to take effect.
