1.TEMPERATURE SENSING COMPONENT DESCRIPTIONS

•Exhaust RTD (Resistance Temperature Device)- Sens1

The RTD (Resistance Temperature Device), used throughout the AD-464 are identical. The main function is to measure temperatures and to transfer this information to a measuring devices for further processing. The RTD used on the AD-464 are rated for 1100° F (593.3° C).

•Sens1 = Exhaust Temperature Sensor

The exhaust RTD (Resistance Temperature Device) is located in the AD-464 burner area exhaust duct and also has electrical disconnects in a junction box for ease of replacement.

•Exhaust 4 to 20 milliampere (4 to 20 mA) transmitter - Trans1

This transmitter is located on the upper right of the main electrical enclosure panel. The exhaust RTD (Resistance Temperature Device) is connected in series with a 24 volt DC power supply, and the current drawn from the power supply is 4 to 20 milliampere (4 to 20 mA) output signal which is proportional to the input signal. The proportional current information is the connected to the PLC (Programmable Logic Controller) for processing. Refer to the AD-464 Ladder Diagram for circuit information.

•24 Volt DC Power Supply

The 24 volt power supply used in the AD-464 is an individual grade switching power supply, rated for 120 volts AC input and 24 volts DC output. Features this device incorporates are:

•Overload protection to protect the load

•Internal failure protection to protect itself

•An output status indicator; this L.E.D. (light emitting diode) indicates the presence of DC output voltage.

•PLC (Programmable Logic Controller) Analog Input Module - Module #2

This device, attached to the PLC , receives the 4 to 20 milliampere (4 to 20 mA) temperature information and processes this information for the PLC.
