Configure the System 450 standard control modules out of the box as stand-alone controls that can provide SPDT control or proportional analog signal control, depending on the model, for a wide range of HVAC, commercial, and industrial process applications. The following standard control modules are available:
- C450CBN-4 control module has one SPDT relay output
- C450CCN-4 control modules have two SPDT relay outputs
- C450CPN-4 control modules have one analog output (0VDC to 10 VDC or 4 mA to 20 mA)
- C450CQN-4 control modules have two analog outputs (0 VDC to 10 VDC or 4 mA to 20 mA)
With a standard control module and the available sensors and transducers, almost any temperature, pressure, or humidity control you may encounter in the field can be quickly replaced with a System 450 control system. See Table 1 for capabilities of the standard control modules.
