Thermo-Hygrostats, Hygrostats
and Programmable Logic Alarm / Control Cards

Our hygrostats and thermo-hygrostats feature reliable, accurate measurement and the ability to be
calibrated on-site. These devices can be used to perform simple control and alarm tasks.

The HCA programmable logic alarm / control card is designed to monitor other devices connected to a RS-485 network.
The HCA features a large choice of logical functions such as comparators, gates, flip flops, delays and real time functions
making it possible to perform fairly complex alarm / control tasks.

HygroStat MB: industrial thermo-hygrostat

► Monitors temperature, relative humidity or a user selectable calculated parameter
    such as dew point
► Available with a large choice of HygroClip probes for maximum flexibility of use
► Application range:  0 to 100 %RH and -50 to 200°C (-58 to 392°F), depending on
    probe
► Two programmable relay outputs
► Networkable: RS-232 or Ethernet (wired or wireless) PC interface and RS-485 port
► Optional LC display
SF65 Series: hygrostat

► Monitors relative humidity
► Two configurations (surface mount and duct mount) both with integral probe
► Application range:  0 to 100 %RH and 23..122°F / -5..50°C or  -30..70°C, depending
    on model
► One programmable relay output
► LC display standard

HCA: alarm / control card with programmable logic

 ► Monitors the measurements and status of devices connected to the RS-485 port
► Monitors the status of up to two external contacts (door contact, push button, etc.)
► Large choice of logical functions such as comparators, gates, flip flops, delays and
    real time functions
► Four single pole double throw (SPDT) independently programmable relay contacts
► Internal memory retains the most recent 680 most recent events, each with a date
    and time stamp
► Operates as a stand alone device or can be integrated in a network monitored by a
    PC with the ROTRONIC HW4 software
