HD 404 ON/ OFF temperature regulator
This regulator may be connected to the transmitters of the series:
HD 2008T, HD 2012T... as long as the temperature configuration of the transmitter
is the same as the regulator
ReguIating range: 4 mA -20° C, 20 mA + 80° C Hysteresis: 0.6÷ 6° C.
Bridge for selecting the function: HD 4049 ON/ OFF relative humidity regulator
This reguIator may be connected to the transmitters of the series:
HD 797T, HD 2007T, HD 2008T, HD 2011T, HD 2012T
ReguIating range: 4 mA 0% R.H., 20 mA 100% R.H.
Hysteresis: 1÷ 6 points of reIative humidity
Bridge for selecting the function: humidify/ dehumidify.
HD 5002, HD 5002/ 5
The HD 5002 or the HD5002/ 5 in combination with temperature and relative
humidity transmitters forms a complete temperature and humidity measuring and
regulating system. Depending on the series, the HD 5002 feeds the transmitter and measures the absorbed current which is proportional to the relative humidity ( terminal IR.H.) and the temperature ( terminal It) .
Voltage drops along the connection wires do not influence the measurement
precision, since the signal is a current and not a voltage.
Regulation is of the three-point type ( heat - OFF - cool for temperature, humidify - OFF - dehumidify for relative humidity) . Also, an aIarm contact is made if the temperature differs by more than 8° C from the set value ( or if humidity differs by more than 15% from the set R.H.) . A dip switch on the rear of the
instrument selects the alarm conditions, high or low for temperature, high or low for humidity.
