Overview
The Triac TMC4 control card is a motor controller intended to be used in electric actuators rated for running current loads
up to 10 amps. The TMC4 control card is available in two versions. An AC version can drive reversible AC motors with a
85-250VAC supply voltage, or a DC version can drive DC motors with a 24VDC supply voltage.
The LCD screen provides easy viewing of status and configuration while a 5-point joystick allows easy navigation through
the various configuration menus and settings. An optional module slot permits expansion on the capabilities of the
controller to support various communication busses or other control and interface options.
The TMC4 provides two main positioning options; proportional or two position. When operated as a proportional controller,
the TMC4 compares an external command signal to a position feedback from a potentiometer connected to the output
shaft of the actuator. When the two signals differ by a given magnitude, the TMC4 controller will energize the motor to
operate either clockwise or counterclockwise to reduce the difference between the two signals. When operated as two-
position controller, the TMC4 receives an open or close command, and drives the actuator clockwise or counterclockwise
until activation of a position limit switch is detected.
The TMC4 is designed to be mounted using PEM Snap-Top spacers for easy mounting and removal without the need for
screws, while still providing a secure mount for most conditions.
The TMC4 must be installed in an appropriate enclosure to avoid electrical shocks. When operating,
high voltages will be present on the controller, requiring caution during the installation process. Power
should be deenergized before making wire connections to the TMC4. A heater and thermostat should
be used when possible, to prevent condensation.

2. Wiring and Operation
The supply voltage and motor should be connected as
shown in the wiring section.
SUPPLY
Supply voltage is connected to terminals (P1-2) and (P1-
3). Line/+ should be connected to (P1-2) and Neutral/-
should be connected to (P1-3). The AC version can
accept a single phase supply voltage of 85-250VAC, 50-
60Hz, while the DC version can accept a supply voltage
of 24VDC. An Earth ground connection is provided on
terminal (P2-7).
MOTOR
For AC type motors, the winding that drives the actuator
clockwise should be connected to the Motor CW terminal
(P1-5), and the winding that drives the actuator
counterclockwise should be connected to the Motor
CCW terminal (P1-6). The motor neutral wire should be
connected to the Motor N terminal (P1-7).
For DC type motors, the wires should be connected to
the Motor CW (P1-5) and Motor CCW (P1-6) terminals
only. When operating DC motors, the Motor CW and
Motor CCW terminals switch polarity to the motor. A
clockwise operation will apply the positive supply voltage
to the Motor CW terminal (P1-5), and a counterclockwise
operation will apply the positive supply voltage to the
Motor CCW terminal (P1-6). The motor wires should be
connected accordingly.
BRAKE
An external brake connection is provided on terminal
(P1-4) to operate spring return type actuators that use a
motor brake to hold the actuator in position. The output
is the same voltage as the supply voltage. The maximum
brake output rating of 300mW, 350V, 120mA continuous
load must not be exceeded.
The AC version of the TMC4 keeps the external brake
output energized until either of the motor outputs is
activated, at which point, the external brake output
deenergizes. The DC version of the TMC4 keeps the
external brake output deenergized until the motor
outputs are activated, at which point the external brake
output energizes.
The brake setting is currently configured exclusively for
use on Triac SRX series actuators and is not
configurable. Care must be taken when using with other
type of actuator motor brakes.
Using brake output on incorrect brake type
may damage the TMC4 card, brake or
actuator.
HEATER
The TMC4 also provides a dedicated terminal (P1-1) for
a heater output that is internally connected directly to the
Line/+ supply terminal (P1-2). An enclosure heater is
strongly recommended to prevent moisture inside the
actuator enclosure. The other heater connection should
either be to motor neutral terminal (P1-7) or supply
Neutral/- terminal (P1-3).
I/O
Standard analog control inputs for 4-20mA, 0-5V, 1-5V,
0-10V, 2-10V should be connected to signal input A1
terminals (P2-2) and (P2-3). 0-20mA and 0-10V analog
feedback signals should be connected to A2 terminals
(P2-4) and (P2-5). This feedback signal is self-powered
by the TMC4 controller, so no loop power is required by
the user.
The TMC4 can also be configured to operate by a
variable resistor input, such as a slide wire or
potentiometer by connecting the ends across the
+24VDC (P2-1) and AGND (P2-3), and the wiper to the
input A1 terminal (P2-2).
The +24VDC output across (P2-1) and (P2-6) is
available to drive a single device up to 30mA or use with
handheld loop calibrator set as 2-wire transmitter to
locally control the actuator while conserving battery
power. Refer to wiring diagrams in following section.
The input A1 and output A2 terminals also serve to
operate as a two-position actuator when configured for
ON-OFF command type using an external 12-24VDC
signal, or using the internally supplied +24VDC output.
In ON-OFF command type, A1 terminal (P2-2) functions
as the Open/CCW input, and A2 terminal (P2-4)
functions as the Close/CW input. This can be useful if
driving AC motor with isolated low power command
signal.
NOTE: If driving the motor through limit switches, the
actuator can be operated like a standard on/off, but will
not display end of position unless limit switches are
wired to the on-board position limit switch connection
header (P5).

4. Setup and Calibration
4.1. Positioning Devices
4.1.1. Feedback Potentiometer (P7)
A feedback potentiometer connected to header (P7) is used to
detect the position of the actuator between the 0% to 100%
limits for modulating and proportional control applications. The
feedback potentiometer is typically coupled to the actuator
output indicator shaft by a set of gears.
To ensure the potentiometer remains within its limits through the
actuator operating range, the actuator should first be moved to
the halfway, or 50%, position. The feedback potentiometer is
then adjusted to the midpoint of its effective electrical range. For
example, a 1kΩ potentiometer should be adjusted to 500Ω. If
the potentiometer jumps from one end to another within the
actuator’s operation range, for example 0Ω to 1000Ω, the TMC4
may not be able to position correctly.
The potentiometer resistance is translated into a 12 bit count value of 0 to 4095 by the TMC4, and displayed in the
“Calibrate Close Pos” or “Calibrate Open Pos” settings in the POSITION CONFIG submenu. When the feedback
potentiometer is at its midpoint, the digital count value shown in either setting will be 2048, as this is the midpoint value
between the limits of 0 and 4095.
It is not critical to adjust the potentiometer to exactly 2048 at the 50% position but should be close so that the value will
not jump between the extremes of 0 and 4095 within the operating range. Centering the potentiometer approximately
between 1900-2200 should be sufficient for most applications.
The effective electrical angle of the potentiometer, actuator rotation angle, and ratio of the feedback gears determine the
maximum and minimum digital count values at the full open and full close positions, and the subsequent range that can be
expected. Typical digital count values are shown below for different gearing ratios or operating angles with the 50%
position set exactly to a value of 2048.
Gear Ratio / Actuator Rotation
Minimum
Maximum
Range
1:1 / 90° 1506 2590 1084
1:1 / 180° or 2:1 / 90° 964 3132 2168
1:1 / 270° or 3:1 / 90° 422 3674 3252
Note that the maximum and minimum values could be swapped depending on the rotation direction of the potentiometer
in relation to the rotation direction of the actuator. The TMC4 will correctly interpret the readings when positions are
calibrated. It is also not important to fall exactly at the values shown as long as the range of operation does not permit the
digital count value to jump from 0 to 4095, or vice versa. However, as the gear ratio or actuator rotation angle increases,
and the range increases, the allowance for deviation is reduced.

4.1.2. Position Limit Switch (P5)
Position limit switches connected to header (P5) are used to detect the Open
and Close position of the actuator for two position and on/off applications.
These switches will stop the actuator at the limits and provide Open or Close
status indication to the TMC4 when “Position Type” is set for Limit Switch in
POSITION CONFIG submenu.
Typically, the auxiliary switches (AOLS and ACLS) in an actuator would be
used, and the motor travel stop switches (OLS and CLS) would be set just
outside of the operating range. The “Switch Action” setting in the POSITION
CONFIG submenu must be set according to if using normally open contact
(N.O. switch action) or a normally closed contact (N.C. switch action).
4.1.3. Stop/Torque Limit Switch (P9)
Motor travel stop or torque switches connected to header (P9) are used to stop the actuator regardless of set position
limits. This switch input should be used when the TMC4 motor outputs are not wired through limit switches, such as for
DC motors. This switch input provides no position indicator for the TMC4 since if an in-line switch stopped the motor from
some over torque situation, a false Open or Close status may be given.
When the motor outputs are wired through limit or torque switches, the switches should be connected through the N.C.
contact to open the motor circuit when activated. As such, the switches connected to the Stop/Torque input (P9) should
preferably also use a N.C. contact configuration. Ensure “Switch Action” setting in the POSITION CONFIG submenu is set
for N.C. action for the stop/torque switches.

Motor outputs connected to motor through switches.
Stop/Torque switch input not required.
