the description on the page is misleading. The real situation is this:
Analog output on Group 1 is capable of outputing 0-10V, 0-20mA and measuring resistance up to 100kOhm
Analog outputs on Group 2 and 3 and on the extensions are only capable of outputing 0-10V
Same goes for Neuron and Axon product line. If you need second AO in current mode for your project, you have two options:add a second PLC as a "dumb" extension and communicate with the master PLC via ModbusRTU, ModbusTCP or SSCP purchase a 3rd party ModbusRTU IO module, such as this: https://www.advantech.com/products/gf-5vtd/adam-4024/mod_5e18f39b-38ef-4033-98f9-1ede917139ee
I am sorry for the incovenience, we will fix the product description shortly.
