•
Nonlinear Output Curves:
Select either of two nonlin-
ear output curves for each control output.
•
Autotuning:
Use the autotune feature to set up your sys-
tem quickly and easily. The internal expert system table
finds the correct PID parameters for your process.
•
Low Power Shutdown:
The controller shuts down and
turns off all outputs when it detects the input voltage drop
below the minimum safe operating level.
•
Process Variable Retransmit:
Scale a temperature or
process and convert it to an analog output for external de-
vices such as chart recorders.
•
Two-Zone Cascade Control:
Control thermal systems
with long lag times, which cannot be accurately con-
trolled with a single loop.
•
Ratio or Offset Control:
Control one process as a ratio
or offset of another process.
•
Remote Analog Set Point:
Scale an external voltage or
current source to provide a set point for a loop.
