Analog Retransmit 1 and 2
One of the optional features often specified with environmental chambers is the circular chart recorder. The
chart recorder is a graphing device used to record chamber data such as temperature, humidity and
pressure over time. An example of a Tenney Chamber with a circular chart recorder is shown below.
Note that the Synergy Controller includes built in Logging features that can often eliminate the need for a
conventional chart recorder.
The Synergy Controller features two analog signals called Analog Retransmit 1 and 2 that can output
setpoints, actual process data and internal PID values. The outputs can either be graphed on the chart
recorder or, in some equipment; the PID output values can be used to control external steam valve (heat),
chilled water (cool) or LN2 liquid nitrogen outputs.
