HD 5002 ON/OFF dual temperature and humidity regulator indicator for panel mounting 96x96. Independent adjustable hysteresis for each channel, two temperature relays, two relays for humidity and one for alarm. Measuring range 4mA = 0% R.H., 20mA = 100% R.H., 4mA = -20°C, 20mA = +80°C. Power supply 24Vac, on request 230Vac.
HD 5002/5 ON/OFF dual temperature and humidity regulator indicator for panel mounting 96x96. Independent adjustable hysteresis for each channel, two temperature relays, two relays for humidity and one for alarm. Measuring range: 4mA = 0% R.H., 20mA = 100% R.H., 4mA = -30°C, 20mA = +130°C. Power supply 24Vac, on request 230Vac.

The HD 5002 or the HD 5002/5 temperature
and humidity regulator controller in combination
with temperature and relative humidity transmitters
forms a complete temperature humidity measuring
and regulating system.

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 alarm contact is made if the temperature differs by more than WC 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.
