HD48 and HD49 series Passive or Active Temperature, Relative Humidity or Dew Point Transmitters
Description

HD48.. and HD49.. series of transmitters measure temperature, relative humidity and the dew point temperature. Models with analog output provide a signal that can be transmitted to a remote display, recorder or PLC. Models with RS485 output can be connected to a PC or PLC. HD48.. series transmitters are active transmitters and accept both direct and 24Vac alternating power supply; depending on the type, they have standard current (4…20mA) or voltage (0…10V) outputs, or a serial RS485 output. HD49.. series transmitters are passive transmitters suitable to be inserted in a 4…20mA current loop. The HD48.. and HD49.. series of transmitters are designed for temperature and humidity control in conditioning and ventilation systems.
