Overview
The DDC420 is a stand-alone controller for heating, ventilation and air conditioning plant. It has five relay outputs, two binary inputs that also count pulses up to 80 Hz, and eight universal points that can each be set as a binary output, binary input, analog output or analog input. Inputs accept the usual temperature sensors (KP10, Ni1000, PT100, PT1000, NTC and others) and 0 to 10 V signals. A backlit graphic display with a set knob and buttons gives local operation, and an integrated web server gives remote operation from a browser with no extra software. The controller communicates over Ethernet using BACnet/IP and has an RS485 BACnet MS/TP master port, an RS232 port for a modem, and a CAN fieldbus for expansion with FBM and FBU modules and RBW room operating units. A battery-buffered clock keeps time for 10 years. Remote TPC touch panels connect to it over TCP/IP.
