Hawk 1000 Section 2 — System Components
Part No. 750-366 2-3
The Module Power Supply powers the Base Unit and the I/O modules. The remainder of the PLC rack is for
the discrete input and output modules, and for analog input module (optional).
I/O modules are used to send and receive control and communication signals to/from other parts of the system.
A Right End Cap Terminator is required to complete the modular communication bus. It attaches to the right
side of the last module in the rack.
An optional analog input module can be added to the PLC to provide additional functionality.
NOTE: The PLC program expects each device to be in a specific slot location. The HAWK 1000 controls
will not function unless all devices are properly installed and configured.
2.3 Human-Machine Interface (HMI)
The HMI displays numerous boiler parameters at a glance and provides easy menu navigation for configuring
system parameters, setting of combustion, monitoring the boiler processes, and managing and annunciating
system alarms.
The HMI communicates with the PLC via Ethernet and is powered by a 24VDC din-rail mounted power supply.
DISCRETE and ANALOG Signal Types
Discrete inputs/outputs are used for signals taking on only one of two
possible states (on/off, open/close, etc.). The input state is represented
by a bit (0 or 1) in the control logic. Example:
Boiler Ready (yes/no)
Analog signals can assume almost infinite values within the fixed
analog input/ output current range of 4-20 mA. The Hawk 1000 PLC
converts this current value to a range in engineering units. Example:
Steam Pressure (0-150 PSI)
