TC UEC-16
The TC UEC-16 provides control for 16 points,
including 8 software-configurable universal points.
Point count includes: 3 Universal Input (UI), 5
Universal I/O (U), 2 Digital Input (DI), 3 Analog
Output
(AOV), and 3 Digital Output (DO).
TC UEC-24
The TC UEC-24 provides control for 24 points,
including 16 software-configurable universal points.
Point count includes: 3 Universal Input (UI), 9
Universal I/O (U), 4 Super Universal I/O (X), 3
Analog
Output (AOV), 5 Digital Output (DO).
Extended Temperature Operation
The TC Compact UEC "R" models support
extended temperature operation, allowing for
rooftop installations.
Hardware
The TC Compact Series consists of the following
major components:
 Input/Output Points
 Power Supply
 Controller Processor
Input/Output Points
 The TC Compact input/output points perform
A/D or D/A conversion, signal processing, point
command output, and communication with the
controller processor. The terminal blocks are
removable for easy termination of field wiring.
 The Universal and Super Universal points
leverage TX-I/O™ Technology from Siemens
Building Technologies to configure an extensive
variety of point types.
 Universal Input (UI) and Universal Input/Output
(U) points are software-selectable to be:
– 0-10V input
– 4-20 mA input
– Digital Input
– Pulse Accumulator inputs
– 1K Ni RTD @ 32°F (Siemens, Johnson
Controls, DIN Standard)
– 1K Pt RTD (375 or 385 alpha) @ 32°F
– 10K NTC Thermistor (Type 2 and Type 3)
@ 77°F
– 100K NTC Thermistor (Type 2) @ 77°F
– 0-10V Analog Output (Universal
Input/Output (U) points only)
 Super Universal (X) points are software-
selectable to be:
– 0-10V input
– 4-20 mA input
– Digital Input
– Pulse Accumulator inputs
– 1K Ni RTD @ 32°F (Siemens, Johnson
Controls, DIN Standard)
– 1K Pt RTD (375 or 385 alpha) @ 32°F
– 10K NTC Thermistor (Type 2 and Type 3)
@ 77°F
– 100K NTC Thermistor (Type 2) @ 77°F
– 0-10V Analog Output
– 4-20 mA Analog Output
– Digital Output (using external relay)
 Digital Output (DO) points are 110/220V 4 Amp
(resistive) Form C relays; LEDs indicate the status
of each point.
 All TC Compact Series models support 0-10 Vdc
Analog Output circuits.
 The Super Universal points may be defined as
either 0-10 Vdc or 4-20 mA Analog Output
circuits.
Power Supply
 The 24 volt DC power supply provides regulated
power to the input/output points and active
sensors. The power supply is internal to the TC
Compact housing, eliminating the need for
external power supply and simplifying
installation and troubleshooting.
 The power supply works with the processor to
ensure smooth power up and power down
sequences for the equipment controlled by the
I/O points, even through brownout conditions.
Controller Processor
 The Unitary Equipment Controller includes a
microprocessor-based multi-tasking platform for
program execution and communications with
the I/O points and with other UECs and field
panels.
