Virtual Channels
The ioLogik E2260 provides virtual channels so you can easily determine the average or deviation values for
any attached temperature sensor. A virtual channel can operate in Average Mode or Deviation Mode. In
Average Mode, up to 6 physical channels are selected and the virtual channel reports the average value of the
selected channels. In Deviation mode, two physical channels are selected and the virtual channel reports the
difference between the channels.
When using virtual channels, if there are errors on any of the selected physical channels, that channel’s
readings will simply be ignored. You can refer to the LED indicators to see if any errors are encountered with
any of the physical channels.
Note that virtual channels only support temperature units and cannot be used with resistance units. Any
channel that is connected to a resistance sensor will be treated as an error channel.
Configuring Thermocouple Input Channels
The ioLogik E2262 provides 8 fixed physical TC input (Thermocouple) channels, each supporting up to 8
different types, including J, K, T, E, R, S, B, N types, and mV voltage inputs. The TC channels are numbered
from channel 0 to channel 7. Moreover, channels 8 to 15 are virtual temperature channels that report a running
average or difference of selected TC channels.
The following table is a list of supported sensor types and ranges.

The status of attached sensors will be reported by the count value, which corresponds to the sensor ranges
shown above. For example, for a K type TC sensor, a count value of 10 corresponds to a 0.1°C reading. Moxa
can only guarantee accuracy within the ranges shown above. Be sure to verify the sensor type. Accurate
readings beyond these ranges cannot be guaranteed.
