2.1.1 Process Inputs

The Synergy Controller has multiple inputs. (See detail above) These are listed in the table below.
Inputs
RTD channels
High Resolution
0-5VDC channels, 16-Bit
Low Resolution
0-5VDC channels, 10-Bit
UUT Temperature Inputs
T-Type Thermocouples
Note: All of these inputs can be logged and checked using the user programmable alarm system.

2.1.2 Input Calibration and Scaling

Each Input can be calibrated for the physical measurement, Ohms, Volts or Degrees C.
Each Input can also be scaled to appropriate engineering units. (See the

2.1.3 Channel Calibration

Each Channel is assigned an input. In addition, channel data can be scaled and offset to accommodate
Channel errors caused by sensor position, thermal gradients, etc.

2.1.4 Channel PIDs

Each Channel has a set of PID constants and variables. Each channel implements a PID control algorithm
that determines its Heat and Cool outputs. The PID variables can be logged for documentation and tuning
purposes.

2.1.5 Channel Primitives

The channel primitives are the algorithms that control each output device such as fans, compressors,
heaters, etc. The Synergy Controller supports multiple instances of the same primitive. For example in the
thermal shock application there are two hot chambers and one cold chamber and thus uses two Heat output
primitives. Each primitive output is displayed in the Events/Digital Outputs folder.
