System 450 Component Requirements
A System 450 control system consists of one control
module, one to three control sensor inputs, and one to
ten outputs that provide On/Off control and/or analog
control. Figure 3 shows an example System 450
module assembly with two input sensors and three
outputs (two relay outputs and one analog output).
Setting up a System 450 Module Assembly
To set up a System 450 module assembly:
1. Determine the controlled conditions, sensor types,
and value ranges required for your application, and
select the appropriate System 450 sensor types.
2. Determine the number and type (relay or analog) of
outputs required to control your application, and
select the appropriate System 450 control module
and expansion modules to provide the outputs.
3. Assemble the control and expansion modules in
the proper order, starting with the control module
on the left.
Note: If you use a C450YNN-1 power module, it
must be plugged into the control module. Plug in
any expansion modules (for your control system) to
the right of the power module.
4. Apply supply power to the module assembly.

You can now set up your control system in the
System 450 reset control module UI.
Note: After you power on your module assembly, you
can set up your control system in the control module UI
before wiring the sensors or outputs to your assembly.
Setting Active/Passive Sensor Jumpers
Before putting your System 450 reset control system
into operation, you must set up each sensor in your
system as either passive or active by positioning the
jumper on the terminal pins on the terminal block
located below the sensor terminal block. See Figure 3.
Temperature sensors are passive (2-wire) sensors and
the corresponding jumpers must be positioned across
both pins. Humidity and pressure transducers are
active (3-wire) sensors and corresponding jumpers
must be positioned on one pin (or removed
completely). Figure 5 shows the jumper positions for
the System 450 example shown in Figure 3.
Sensor 1:
(or removed) sets Sn-1 to Active (Pressure).
