Automation station for HVAC and building control systems.
● System functions (alarming, scheduling, trending, access protection with individually
definable user profiles and categories)
● Freely programmable (close resemblance to CEN standard 11312). All function blocks,
available in libraries, can be graphically connected.
● Engineering and commissioning with the ABT Site Tool using graphical function charts
● BACnet communication, in compliance with the BACnet standard including B-BC profile
(Rev. 1.15)
● Generic object viewer for device local data points via an embedded web-based interface
● Wireless connection for engineering and commissioning
● Integration of Modbus data points via RTU
● Direct connection of field devices
Compact automation station for BACnet MS/TP

● Resistance sensors 1000 Ohm, 2500 Ohm, 2650 Ohm, 1000...1175 Ohm (for setpoint shift)
● Active sensors DC 0 ... 10 V
● Current measurement analog DC 0...20 mA or 4...20 mA, (inputs U1, U2, U7, U8)
● Binary potential-free contacts for signaling functions
● Counter to 25 Hz (electronic switch to 100 Hz)
● Analog outputs DC 0…10 V
