Optimizer Essential Plant Controller

Optimizer Essential Plant Controller with 28 Onboard IO leveraging the Niagara® Framework. Ideal for energy efficient control of small to medium plant applications integrating up to 35 Unitary or VAV controllers.

Overview

The Essential controller is a next generation small plant controller

that utilizes the Niagara Framework® with optional Edge licensing that includes Honeywell Panelbus, BACnet, MODBUS and M-Bus drivers,

or full Niagara integration and driver licensing to meet additional customer application needs. The

Essential is a freely programmable IP device powered by a 64bit

dual-core i.MX processor, with 28 onboard input and output

control points that provide extremely flexible control options.

Using the power of the Niagara Framework®, the Essential

controller provides both Ethernet & Serial integration options

and is a native profile BACnet™ Building Controller (“B-BC”).

Features & Benefits:

The Essential controller has 28 onboard input and output control points (16 universal I/O channels, 4
relay outputs, 4 solid state relay outputs, and 4 digital inputs). The controller features:
RS-485 ports for BACnet™ MS/TP, Panel Bus (Legacy IO and SnapON IO module devices), Modbus RTU, and M-Bus.
Ethernet ports for BACnet™ IP devices, Modbus TCP/IP, and C-Bus.
RJ11 port interface for HMI devices.
The controller also has a USB Type-C interface port to connect with a computer for serial communication.
The controller can
be mounted on DIN rail in either a horizontal or vertical orientation.
Additional features:
Three RS-485 non-isolated / no
galvanic ports (One touch flake and
Two via terminals) and two Ethernet
ports / two switched IP ports.
Ethernet ports can be configured
as in isolated or switched ports.
RJ11 port to connect with a dedicated
HMI device for field operations.
Touch flake connections to support
RS-485 IO module devices.
The switched Ethernet IP ports
support both daisy chain operation
and RSTP (Rapid Spanning Tree
Protocol) which allows a fault
tolerant network to be created.
Built-in RSTP switch allowing loopfree
forwarding network topology.
i.MX 8M Mini, dual Arm® Cortex®-A53
processor, long life industrial
grade, Frequency: 1.2 GHz.
Supports BACnet™ SC configuration
within the Niagara Framework®.
Conforms to BACnet™ Standard
ANSI/ASHRAE 135 protocol
version 1.15 (ISO 16484-5).
