Appendix A Setting up Analog Outputs on the Model 8872
The Model 8872 does not use any custom analog output boards, but rather has the capability to
talk to a wide variety of Modbus-based analog output modules commonly available. The most
common we use (and the one for this illustration) is the Acromag 972/973EN-4004 device.
If purchased from Agilaire, the units will be preprogrammed with IP addresses compatible with
the Model 8872’s External I/O network. The first module will be 10.0.0.151, the second will
be 10.0.0.0.152, etc.
The unit is DIN-rail mounted, and must be given a 15-36 VDC power supply (not provided by
8872, typically a DIN rail power supply). The user should then connect the module to the
“External I/O” network (rear panel) through a basic passive Ethernet switch:
