3-3.2.2 Universal Inputs / Outputs
The MiniMAX controllers are equipped with seven Universal Inputs/Outputs which can be configured
with MAXCon software to be used as inputs or outputs. Each Universal Input/Output has a signal
terminal (+) and a reference terminal (–). The types of inputs and outputs that can be configured and
the respective range for each are shown in Table 3-7 below.
When a UIO on a MiniMAX controller is configured as a Thermistor input type, it is designed to be used
with Innotech SEN Series Detectors. The sensing range and accuracy for the SEN Series Detectors is
as follows:
• Nominal sensing range: -5°C to 60°C
• Accuracy +/-3.5%FS (R25°C = 10kΩ)
A single transformer may be used to supply voltage to more than one controller, but you must ensure
that the planned load is well within the rating of the transformer. The transformer output terminal
designated as AC Neutral must be solidly earthed to the main earth link of the enclosure panel. The
dedicated power input terminals are Terminals 1 and 2 and are detailed in Table 3-6 below.

It is not recommended to use the Pulse Counter on these controllers for accumulation as these controllers are not
equipped with battery backup or flash RAM. The MAXIM II, MAXIM III, and MAXIM 1010 controllers are better suited
for such situations.
