TC-6100 Cybertronic®
Temperature Controller
The TC-6100 Cybertronic
Temperature Controller is a
solid-state proportional
temperature control device. It is
used with M100G actuators in air
or liquid-flow systems. It may
also be used with the EP-8000
Electro-Pneumatic Transducer
or any other device which
operates on a 1 to 18 VDC
control signal. The TC-6100 has
both direct and reverse acting
outputs with separate direct and
reverse acting bandwidth
settings.
The controller consists of three
basic circuits: a resistance
bridge, a direct acting amplifier,
and a reverse acting amplifier. A
difference between the sensing
element resistance and the set
point resistance produces a
proportional voltage which is
amplified to provide a 1 to
18 VDC control output. The
output is direct acting when the
sensed temperature is above
the set point and reverse acting
when the sensed temperature is
below the set point. A maximum
of 20 M100G actuators can be
controlled by each output signal.
The TC-6100 is available with a
dual resistance bridge. The dual
bridge consists of a main bridge
and an auxiliary bridge. This
offers a number of control
options, for example, mastersubmaster control. Bridge
circuits, whether the dual bridge
or the standard single bridge,
can be used with local or remote
sensing and local or remote set
point adjustment. The TC-6100
has provisions for setup, and
setback may be accomplished
by using an AQ-6001 Remote
Set Point Control. Setup and
setback cannot be used at the
same time. Remote
potentiometers may be used to
raise or lower the set point,
depending on the season, during

unoccupied periods. An
AQ-6001 may be used for
remote manual set point
adjustment; an AQ-4102 MotorDriven Reset Control may be
used to remotely reset the set
point of either a local or remote
adjustment.
Appropriate sensing elements
may be chosen from any of the
Cybertronic 1000-ohm nickel
wire resistance elements. All
electronic sensing and control
provide rapid response to
temperature change. Special
circuitry gives protection against
accidental short circuits across
the signal output.
A power supply is incorporated
on the circuit board to provide
power to the TC-6100 circuits
and any external requirements
(40 mA max). The integrated
circuit voltage regulator will go
into thermal limit to protect the
TC-6100 Temperature Controller
transformer in the event that the
supply has its output shorted.
Stick-on labels for corresponding
Celsius scales are packaged
with each unit.

The element connected to the
main sensing circuit must always
sense the smaller temperature
variation. Both sensing circuits
have the same initial sensitivity,
but since the auxiliary circuit
error signal is affected by the
ratio adjustment, its sensitivity
may equal but never exceed that
of the main circuit. The effect of
the wider temperature variation
is reduced by the ratio
adjustment to balance the main
error.
Operation
The TC-6100 has both direct
and reverse acting output
signals. When the temperature
at the main sensing element is
equal to the set point of the main
sensing circuit, both outputs are
minimum (less than 1 VDC). If
the temperature increases above
the set point, only the direct
acting output signal increases in
proportion to the change. If the
temperature decreases below
the set point, only the reverse
acting output signal increases in
proportion to the change.
All other connections on the
TC-6100 are made to a
numbered terminal strip. All
wiring must be in accordance
with applicable electrical code
requirements. See bulletin
TC-6100-A for further wiring
information as well as checkout
and adjustment instructions.

The TC-6100 is furnished in its
own enclosure that may be
mounted on a DZ-6001 DIN rail
or surface mounted with four #6
screws.
When the controller is furnished
with an auxiliary sensing circuit,
either direct or reverse
readjustment is possible. Both
the main and auxiliary sensing
circuits produce error signals
proportional to the difference
between their sensed
temperatures and their
setpoints. The Ratio Control
adjusts the amount of auxiliary
error signal which is combined
with the main error signal to
drive the output amplifiers.

Supply voltage connections are
made to pins using a CZ-6002
cable, or the cable can be cut
and 24 VAC can be wired there.
The TC-6100 has a 7-in.
(178 mm) cable with plug for
passing along the AC power to
another 6100 Series device.
