2.3.9 USB-Ethernet Adapter
The IPS range of programmable controllers can be
connected to a computer via an external adapter. This
adapter must be used in the processing environment
for the application download in the controller. This
adapter is not set up for fixed or continuous connec-
tion. If the adapter should be kept connected continu-
ously, the room temperature must not exceed 50°C
(122°F).

2.4 Powering the High
Pressure CO2
Controller
Retail Solutions supplies a wide variety of 24VAC
transformers with varying sizes without center taps.
(Table 2-9)
shows the transformer sizes and are non-
center-tapped.
2.4.1 Choosing Transformer Sizes
The transformer used to power the High Pressure
CO2 controller should have at least a 30VA rating.
The High Pressure CO2 controller should not share a
transformer with any other devices.
Figure 2-5
shows
how to wire the transformer to the High Pressure CO2
controller.
