.ECB-203 Series 2018-05-30T13:40:58+00:00

ECB-203 Series

Distech Controls

The ECB-203 Series controllers are microprocessor-based programmable controllers designed to control units such as RTUs, FCUs, UVs, HPUs, AHUs, and chilled ceilings. This controller uses the BACnet® MS/ TP LAN communication protocol and is BTL®- Listed as BACnet Application Specific Controllers (B‑ASC).

These controllers meet the requirements of the following applications: Rooftop Units, Fan Coil Units, Chilled Ceilings, Heat Pumps, Unit Ventilators and Small Air Handling Units.

BACnet B-ASC 14-Point Programmable Controllers

Flexible Inputs and Outputs

This controller has various input types including resistance, voltage, and digital-based ones. Moreover, it provides digital, floating, pulse width modulation, and proportional control outputs for valves, heating elements, fans, and lighting applications. This controller covers all industry-standard HVAC unitary applications.

Highly Accurate Universal Inputs

Highly accurate universal inputs support thermistors and resistance temperature detectors (RTDs) that range from 0 Ohms to 350,000 Ohms, as well as support for inputs requiring 0 to 10VDC or 0 to 20mA with an external resistor. This provides the freedom of using your preferred or engineer-specified sensors, in addition to any existing ones.

Overview

  • 6 universal inputs
  • 5 digital outputs (TRIAC)
  • 3 universal outputs
  • 15 VDC power supply to power 4-20mA transducers such as duct static pressure, etc.
  • 1 calendar, 2 schedule, 8 loop (PID), and over 200 BACnet objects
  • Some models available with environmental protection
  • ECB-253 includes live graphics color display (integrated LCD operator interface)
  • Support up to 4 Allure series communicating sensors
  • Open-to-Wireless™ Solution: support of up to 18 wireless battery-less inputs

Rugged Inputs/Outputs

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

Environmental Protection

The ECB-203 model with Environmental Protection has a conformal coating applied to its circuit board for an extra degree of protection for use in humid regions and it is ideal for enclosed roof-top unit applications.

Open-to-Wireless

The controllers are Open-to-Wireless™ ready, and when paired with the Wireless Receiver, work with a variety of wireless battery-less sensors and switches, to reduce the cost of installation and minimize the impact on existing partition walls. Available with an optional Wireless Receiver that supports up to 24 wireless inputs to create wire-free installations.
