Brainchild DL200 Piping Controller

DL200 is a data logger that 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 Controller Model NC200 after equipping the unit with an 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.
