1.1 Introduction
DL200 is a data logger which can connect up to 247 Network
Temperature Controllers Model NC200. This unit can write all
commands and read all data to and from each Network
Temperature Controllers Model NC200 after equipping the unit
with a HMI or PC via RS-232 port. The unit provides a dry
contact which will be closed when one or more of the Network
Temperature Controllers Model NC200 are outside of high and
low limits or hardware failure occurs.
