Hello! Let's say that I already have hardware but it does not meet my current needs (not in papers at least). I have V570 with V200-18-E2B snap-in. The problem is that I need an analog output that ranges from -5V to 5V, but I only have two analog outputs that run from 0-10V. So, here's my question: Is it possible to connect VOut 0 to positive terminal of control valve (valve that i need to control with -5V to 5V) and VOut1 to negative terminal of that valve - thus completing circuit through Analog outputs (making one output source other sink)? Note: This can be done with one 0-10V output and one relay with two pairs of NO and NC contacts, but the process requires fast and frequent switching between positive and negative values on the output... Thanks in advance! PS If I missed forum section please let me know.
