OUTPUT TRANSDUCERS — For both stand-alone and CCN systems (based on the stages of heat addition or rejection required) the Aquazone™ system control panel can be ordered with a combination of 2-stage and 4-stage output transducers to provide 2, 4, 6, or 8 stages. The combination desired is speci- fied in the 50RLP model nomenclature in digit 6 to specify heat rejection stages and digit 7 to specify heat addition stages. See Fig. 1. If variable speed cooling tower fan operation and/or

modulating valve operation for steam or water are utilized, no output transducer card is specified. The output transducer is a solid-state multi-stage device used for staging control from a single analog signal. Output transducers are located in the upper left hand corner of the Aquazone System Control Panel underneath the pump control relays. See Fig. 4. Specifications for the pump control relays are as follows:

Supply Voltage:

24 vac ± 10% @ 100 mA,

 

24 vdc ± 10% @ 50 mA

Input Signal:

4-20 mA

Output:
