Programmable DDC Controller
Programmable DDC Controller
1 Introduction:
1.1 ASENWARE Programmable DDC Controller is a Direct Digital Controller for HVAC(Heating,Ventilating,and Air Conditioning) and BAS(Building Autocontrol System),Factory Power Monitor.
1.2 Opened MODBUS protocols.
1.3 Two way configuration, keyboard of the DDC or from computer download, secondary program software is free!
1.4 Two way program download,from RS232 or RS485 (MODBUS protocols)
1.5 Online emulator, for test the control logic, it is free too!
1.6 General-utility I/O port technology, AI and DI,AO and DO can exchange, AI ports can be smart set to PT1000,NTC,0-10VDC,4-20mA by software (depend on the hardware version)
1.7 High reliability, CE certification.
1.8 Good shape, easy installation.
1.9 Excellent cost effectiveness,30%~50% saving cost than others.
