Nortec Industries NHRS Series manual Controls, A.Standard Controllers, C.Signal By Other, 10-10

1.CONTROLS

A.STANDARD CONTROLLERS

(1)NORTEC has a wide range of modulation packages for use with the NHRS humidifiers. The packages all provide humidity controllers complete with point for accuracy up to ±3%. For accuracy up to ±1% a high precision humidistat is required.

B.FULLY INTEGRATED MODULATION ADAPTER

(1)The NORTEC NHRS includes all the circuitry necessary to accept a modulating signal from most modulating humidity controllers with a set point supplied by others. This allows the unit to easily interface with a Building Automation System.

(2)For more accuracy, the set-point is controlled at the humidifier and the integrated controller can accept a direct transducer signal. The accuracy of the humidifier to changing conditions will be dependant on the accuracy of the signal.

C.SIGNAL BY OTHER

(1)When modulating humidity controllers or transducer signals are supplied by others, the NHRS humidifier can accommodate most standard signals, including:

(a)0-10 vdc

(b)2-10 vdc

(c)0-5 vdc

(d)1-5 vdc

(e)0-20 mA

(f)4-20 mA
