Chapter 1 | G3Pro overview
• Thermal Control Unit (TCU)—8-pin connector that provides
control of the TCU, if used. Used only on vessels larger than 250 L.
• TruLogic (required for DeltaV platform)
• AUX-1 through 4—5-pin (0–10 V) auxiliary connectors for control
loops. Note: Spare connectors are available as needed.
• AI-1 through 4—5-pin analog (0–20 mA) inputs. They are input
only, with no control capacity.
• Vessel Adapter Box (VAB)—Enables you to easily switch vessels
according to the requirements of the process.
Auxiliary input pin-out
The connectors marked AUX 1 through 4 are for control loops requiring
feedback from the controller and contain analog input (AI) and analog
output (AO).
