HUMIDITY & TEMPERATURE CONTROLLERS

MODEL : PE 9100

Premier’s Model PE 9100 is a controller for humidity and temperature and also a logger. It has three output for SRR interface to efficiently control the Humidity and Temperature. PE 9100 is an ON/OFF Controller with logic for compressor ON/OFF (with programmable Time delay) and Heater ON/OFF for temperature control and stem ON/OFF for Humidity Control.
PE 9100 has RS232 output for computer or Printer interface and also has the built in Real Time Clock along with non-volatile memory . It prints data at every Print Interval in On-Line Mode. In Off – Line Mode it stores all the datain its memory which can be printed on the Dot Matrix Printer thro Serial Port or can be taken on Computer.

Features : On/Off with hysterisis or Proportional Control.
Controls both RH and Temperature.
Two 5 Amp relay contacts.
Panel mounting size.
Adjustable dead bands for Relative Humidity and temperature.
Low Relative Humidity measurement – optional.
RS 232 / RS 422 output for PC interface.
Real Time Clock with calendar for Datalogging.
