Output expansion module type ABS CA 781
Control of an extended number of pumps
With output expansion module type ABS CA 781 you can control an extended number of pumps with your existing PC 441 system. It also creates new opportunities to extract detailed information on alarms, pump status, level trends, and more.
Main design features
Output expansion module CA 781 expands the system with 8 digital and 2 analog output signals and gives the opportunity to control other equipment in the installation. In this way, CA 781 gives you greater flexibility to use the PC 441 concept in a manner that best suits your specific needs.
The module is connected to the system via CAN bus communication and needs power supply via an external source.
