UMC800 Overview
Introduction
The Universal Multi-loop Controller (UMC800) is a modular controller (see Figure 1) designed to address the analog and digital control requirements of small unit processes. With up to 16 analog control loops, four set point programmers, a set point scheduler, and an extensive assortment of analog and digital control algorithms, the UMC800 is an ideal control solution for furnaces, environmental chambers, ovens, reactors, cookers, freeze dryers, extruders, small boilers, and other processes with similar control requirements.
modating up to 64 universal analog inputs, 16 analog outputs, or 96 digital inputs or outputs, the UMC800 provides the appropriate balance of input and output hardware for these smaller unit processes.
Split architecture
The UMC800 uses a split architecture that separates the control functions from the operator interface functions to provide greater installation flexibility.
Controller
The controller posed of a CPU with two munication ports, power supply, and a backplane assembly. It incorporates a card rack that is capable of supporting up to 16 input and output modules that can be mixed to satisfy the hardware requirements of a specific application.
Modules are available in ten different configurations to support both analog and digital inputs and outputs of various types and signal levels. Each module has a removable terminal block accepting #16 AWG wire.
An optional RS485 munication card that supports both slave data exchanges with a host PC for centralized operation and data management and/munications via a Modbus RTU master to other Honeywell or 3rd patible products.
Operator interface
The operator interface uses a color graphic LCD display to provide a variety of screen presentations for viewing control loops, s
