Expansion Module Option
For those applications requiring more than eight input modules Qualitrol offers an Expansion
Module that will accept an additional eight input modules doubling the input capability of the
509ITM unit. The Expansion Module uses the same input modules described in the
hardware section of this manual and all the software features of the standard input modules
apply to these additional inputs (e.g. controlling relays, data logging, driving output current
loops, etc.). The Expansion Module communicates to the 509ITM unit through a digital
cable/wiring and has the same input power supply range as the 509ITM unit.
NOTE:
When first applying power to the 509ITM and Expansion Module it may take up to
45 seconds for the microprocessors to establish communications before the input
modules installed on the Expansion Module to take affect (e.g. on the LCD display,
control relays, etc.) in the 509ITM unit.
NOTE:
After establishing communications any changes in the Expansion Module inputs will
be reflected in the 509ITM within 15 seconds. Therefore if the measurement of any
parameter is time critical, Qualitrol recommends installing that input module directly
in the 509ITM.
