 Dual-channel extension module DAC (0 — 10 В) WBE2-AO-10V-2

== Hardware ==


The module is built on the MCP4728 digital-to-analog converter and supports two output channels with a voltage from 0 to 10 V. '''In version 2.2, the output current is increased to 10 mA.''' The module can withstand short-term (a few seconds) output short-circuit.


== Pinout ==

The signals of the converter are output to the O1-O3 terminals of the extension module.

==Configuration== 

Configuration is set in the web interface. Section Configs => Hardware Modules Configuration.
Next, in Internal slot 1 or in Internal slot 2, select  "WBE2-AO-10V-2: Dual channel analog voltage output (0-10V) module" and click Save.


The device is detected immediately, no reboot is required.

In the web interface, the module channels appear in the Analog Outputs section and are called MOD1_O1 and MOD1_O2 for the module installed in the first connector, MOD2_O1 and MOD2_O2 for the module installed in the second connector.
The voltage value ('''in millivolts''') is published in mqtt-topics ''/devices/wb-dac/controls/''.
