Tender text

Additional module for the equipment of the Wilo-CC/CCe/SC/SCe-HVAC system switchgear series and for the CC/CCe/SC/SCe Booster for signal selection (minimum value) of two to eight measurement points for index circuit evaluation. The DDG impulse selector outputs the signal with the smallest value (minimum value) from a minimum of 2 to a maximum of 8 input signals 0(4)-20 mA. If several sensors are used on-site, then the most minimal of the values can be determined with the aid of the DDG impulse selector.

Version

Impulse selector for installation in a switch cabinet, channel selection with DIP switches accessible from the front, LED operation and output signal, galvanic separation between measurement signal and supply voltage, fixation on 35 mm DIN rail. Retroactive installation of the DDD impulse selector in the switchgear is possible. Installation by Wilo Customer Service is recommended.
