The VP-2040 can provide one optional 4-20mA analog output,
supporting the access of the DCS system. The user can, through the
communication interface, set the parameter value corresponding to
the analog output. The maximum load resistance of the interface
should not exceed 500 Ohms.

Figure 5-4: VP-2040 Analog Output Capability
On some sites, due to different transmission cables or loading
conditions, the analog output at the high end appears to be non-
linear. VP-2040 provides a settable magnification factor. By
modifying the magnification factor, the user can adjust the proportion
factor of the output curve.
The analog output can be set as any of the items in the table below:
