Features

The ECB-400 Series can also be used for lighting control applications. This controller uses the BACnet® MS/TP LAN communication protocol and is BTL®-Listed as BACnet Advanced Application Controllers (B-AAC).

These controllers meet the requirements of the following applications:

  • Air handling units
  • Chillers
  • Boilers
  • Cooling towers
  • Heat-exchangers
  • Pumps
  • Lighting control

This controller has various software configurable universal inputs and software configurable universal outputs, and covers all medium to large-size industry-standard HVAC applications.

Rugged hardware inputs and outputs eliminate need for external protection components, such as diodes for 12V DC relays.

  • 12 universal inputs including 4 for fast pulse counting and metering applications
  • 12 universal outputs (ECB-400 Series), 8 digital outputs (TRIAC), and 4 universal outputs (ECB-403 Series)
  • Optional HOA switch with potentiometer to locally override and monitor overridden outputs
  • 2 calendar, 10 schedule, 30 loop (PID), and over 300 BACnet objects
  • 15 VDC power supply to power 4-20mA transducers
  • Internal alarm functionality
  • ECB-450 and ECB-453 include live graphics color display (integrated LCD operator interface)
  • Open-to-Wireless™ Solution: support of up to 28 wireless battery-less inputs
