Assortment / System Description

8 PXC4 automation stations
For the control of primary plants.
● Compact automation station for HVAC and building control systems, freely
programmable
● System functions such as alarming, schedulers, trend functions, and access
security
● Stand-alone application or for use within a building automation and control
system
● Direct connection of field devices
● Extensions possible with TXM I/O modules
● Integration of communicative field devices, e.g. variable speed drives via Modbus
● Engineering and commissioning with the user-friendly ABT Site tool
● BTL tested BACnet communication on IP (BACnet/IP and BACnet/SC) or
BACnet MS/TP, in compliance with the BACnet standard including B-BC profile
(Rev. 1.15)
● WLAN interface for engineering and commissioning
● BACnet/SC support (as BACnet/SC node only)
