Analog Output Expansion Module
The Analog Output Expansion Module (AOX-4) provides variable voltage or current control signals
from the MAG in order to drive various control devices. The AOX-4 is inserted into the snap track of
the MAG. Only one AOX-4 board can be ordered providing a maximum of four output channels.
Jumpers on the AOX-4 allow the user to configure the output ports to one of the following
current/voltage selections:
•
0–5 Vdc
•
0–10 Vdc
•
0–5 mA
•
0–20 mA
For more information on the Analog Output Expansion Module, see Bulletin No. IM 607.

MicroTech Monitoring and Networking Options
PC Monitoring
A PC (personal computer) equipped with the appropriate Monitor software can be used to provide a
high-level interface with a MicroTech network (see PC specification below). Monitor software features
a DOS-based display, multilevel password access, and advanced trend-logging. The PC can be
connected directly to the MAG. For more information on connecting the PC to the controller, refer to
“PC Connection” in the “Field Wiring” section of this manual.
For the most convenience and best operation, the PC should be considered dedicated to the
MicroTech system. However, you can exit the Monitor program to perform other tasks without
affecting equipment control. Refer to the user’s manual supplied with the Monitor software for
additional information.
