17.4.6 RTD Sensor Wiring
The Synergy Nano Plus supports two 3-wire RTD inputs. Four RTD types are supported, DIN 100, DIN 500,
JIS 100 and JIS 500. These sensors connect to the Olympic board P2 connector according to the table
shown below. These sensors can be used for air temperature or product temperatures.

17.4.7 Voltage Sensor Wiring
The Synergy Nano supports four high resolution 0-5VDC process inputs. These can be Temperature inputs
(scaled F to C), Vaisala temperature compensated and un-Compensated humidity inputs and other types
including pressure. These voltage sensors connect to the Olympic board P2 connector according to the
table shown below. Precision 250 ohm resistors are available to convert these voltage inputs to 4-20 mA
inputs. For more information see the 4-20mA Sensor Wiring Section 17.3.3 below.

The Synergy Nano supports eight low resolution 0-5VDC process inputs. These can be used for compressor
pressure and other system and non-critical measurements. These voltage sensors connect to the Olympic
board P2 connector according to the table shown below. Precision 250 ohm resistors are available to use
these voltage inputs with 4-20 mA sensors. For more information see the section below.
