17.4.8 4-20mA Sensor Wiring
The Synergy Nano Plus can accommodate up to four precision 4-20 mA transducers and up to eight low
resolution 4-20 mA transducers. A precision 250 ohm resistor is required for each transducer. This section
explains the wiring and setup procedure and provides examples.
CAUTION! : The voltage inputs on the controller will be damaged if the 4-20 mA signal is
attached without a 250 Ohm Resistor.
17.4.9 Process Input Wiring
The Synergy Nano Plus supports four process voltage inputs. These inputs connect to the Olympic board
P2 connector according to the tables shown below. These inputs can be used for any sensors including air
temperature, product temperature, Vibration (GRMS), Pressure (Altitude), etc. These process inputs can also
be used with 4-20 mA transducers using the supplied precision 250 Ohm resistor (TE1924).
