Together this equipment can and was utilized to measure and control the following.
8 Total Digital Inputs
in this case only one was used for a conventional switch event, the bilge pump in the engine room. Two others were used utilizing the CPU’s high speed counters to measure a magnetic pulse sensor installed on the vessels two Lugger main engines giving RPM.
24 Total Digital Outputs.
These were used to control systems such as hydraulic pumps, running lights, horn, wipers, lighting and ventilation. These outputs are controlled by user input in the wheelhouse using a Siemens KTP700 touchscreen. In addition to these systems an output was used to operate a buzzer for alarm purposes.
14 Analog Inputs.
Four of these inputs were used to measure voltages from two Engine Lub Oil Pressure senders (0-100Psi) and two Transmission Pressures senders (0-600Psi). Two were used to measure resistance of temperature probes (-40-302F) for coolant temperatures. Two were used to measure current from Temperature Transmitters measuring Thermocouples for Exhaust Gas Temperatures (32-2282F).
