Overview
Function
UDC2800 Limit Controllers accept input signals from any of several
types of external sensors such as Thermocouples (T/Cs) and
Resistance Temperature Detectors (RTDs). It conditions these
signals, as necessary, to derive the equivalent Process Variable (PV)
value that drives various circuits in the controller.
The equivalent PV signal is compared with the Limit control set point
and any error signal from the differential amplifier de-energizes the
coil of an electromechanical, single-pole, dual-throw (SPDT) limit
output relay.
When de-energized, the output relay “Locks Out” and remains that
way until the PV input signal drops below the High Limit Set Point or
goes above the Low Limit Set Point and the controller is reset
manually via the keyboard or from a remote location (Contact Input
Option).
The contact of the output relay terminates at the rear terminal of the
controller to which you make the appropriate field wiring
connections.
A flashing “LIMIT” in the lower display indicates that the output relay
is de-energized.

High Limit Controller
When the PV input signal is below the limit set point, the output relay
energizes. If the PV signal exceeds the limit set point, the output relay
de-energizes and the flashing “LIMIT” display is turned on.
When the PV signal returns to a value below the limit set point, the
controller can be reset manually using the RESET key or Contact
Input Option.

Chapter 2 - Introduction

13
Low Limit Controller
When the PV input signal is above the limit set point, the output relay
energizes. If the PV signal falls below the limit set point, the output
relay de-energizes and the flashing “LIMIT” display is turned on.
When the PV signal returns to a value above the limit set point, the
controller can be reset manually using the RESET key or Contact
Input Option.
Easy to read displays
The dedicated vacuum fluorescent displays with multi-language
prompts make the operator interface easy to read, understand and
operate. Programmed sequences of displays assure quick and
accurate entry of all configurable parameters.
Easy to operate
Simple keystrokes let you select input and range configuration, set
the operating parameters that meet you process control needs now,
and change them later to meet new ones.
Mount anywhere
This instrument is intended for industrial control applications. It
must be panel mounted with the wiring terminals enclosed within the
panel. The instrument is environmentally hardened and, when
suitably enclosed, can be mounted anywhere in plant or factory, on
the wall, or even on the process machine itself. The front face is
NEMA3 and IP55 rated and can be easily upgraded to NEMA4X and
IP66 for the most severe hose-down applications. It withstands
ambient temperatures up to 55°C (133°F) and resists the effects of
vibration and shock.

Chapter 2 - Introduction

Bluetooth communications
The Bluetooth connection provides a non-intrusive wireless
connection with the instrument and maintains NEMA4X and IP66
integrity.
No need to get access to the back of the controller to communicate
with the instrument, no need to take your screwdriver to wire the
communication cable, no wiring mistake possible. You can now
duplicate an instrument's configuration upload, or download a new
configuration in a matter of seconds, just by connecting your mobile
device to instrument through Bluetooth.
Connect & Upload: It takes less than 2 seconds to upload configuration
from an instrument. You can then save the configuration file onto
your mobile device for review modification, or archiving.
Furthermore, the software and app also give you important
maintenance information on the controller: instantly, get information
on the current operating parameters, digital inputs, and alarm status,
identify internal or analog input problems.
Questions: What if I have several controllers on the same panel? How
can I be sure I am communicating with the correct one?
Answer: The UDC device's Bluetooth ID appears in the
communications group on the controller screen, each controller is
assigned with different Bluetooth ID's, user can identify same
Bluetooth ID in the menu under the device list and connect to the
controller.
