Note 1: Install the supplied 249 ohm resistor between terminal #1 and #2 for linear current inputs.
Note 2: Default setting: Pt100 input.
The range of linear input and feedback value is adjustable. Range of input feedback: -999 ~ 9,999. Take 0 ~ 20mA input as
example, -999 refers to 0mA input, and 9,999 refers to 20mA input. If we change the range to 0 ~ 2,000, 0 will refer to 0mA
input, and 2,000 will refer to 20mA input. 1 display scale = 0.01mA.

Safety Information
WARNING! ELECTRIC SHOCK DANGER
1. The SLM series is an OPEN-TYPE device and therefore should be installed in an enclosure free of
airborne dust, humidity, and vibration. The enclosure should prevent non-maintenance sta from
operating the device (e.g. key or special tool is required to open the enclosure).
THIS CONTROLLER IS AN OPEN-TYPE TEMPERATURE CONTROLLER. MAKE SURE TO EVALUATE ANY DANGEROUS
APPLICATION IN WHICH A SERIOUS HUMAN INJURY OR SERIOUS PROPERTY DAMAGE MAY OCCUR.
1. Be sure to tighten terminals to the correct torque of 0.19 Nm. Use solid or twisted wire from 14AWG
to 28AWG.
2. Protect the controller from dust or foreign objects to prevent controller malfunction.
3. Do not modify or disassemble the controller.
4. Do not connect anything to the unused terminals.
5. Make sure all wires are connected to the correct polarity of terminals.
6. Do not install and/or use the controller in places subject to: (a) Dust or corrosive gases and liquid (b)
High humidity (c) Vibration and shock (d) EMI / RFI (e) high temperature.
7. Power must be turned o when wiring, installing or uninstalling expansion modules (SLM2), or
changing a sensor.
8. Be sure to use wires that match the thermocouple types when extending or connecting the
thermocouple wires.
9. Use wires with correct resistance when extending or connecting a platinum resistance thermometer
(RTD).
10. Keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the
controller and route power wires as far as possible from load wires to prevent interference and
induced noise.
11. This controller is an open-type unit and must be placed in an enclosure away from high temperature,
humidity, dripping water, corrosive materials, airborne dust and electric shock or vibration.
12. Make sure power cables and signals from instruments are all installed properly before energizing the
controller, otherwise serious damage may occur.
13. To prevent electric shock, do not touch the terminals in the controller or try to repair the controller
when power is applied.
14. Use a soft, dry cloth to clean the controller. Do not use acid or alkaline liquids for cleaning.
15. This instrument is not furnished with a power switch or fuse. Therefore, if a fuse or power switch
is required, install the protection close to the instrument.
16. Note: This controller does not provide overcurrent protection. Use of this product requires that
suitable overcurrent protection device(s) must be added to ensure compliance with all relevant
electrical standards and codes. A suitable disconnecting device should be provided near the
controller in the end-use installation.
WARNING: To minimize the risk of potential safety problems, you should follow all applicable local
and national codes that regulate the installation and operation of your equipment. These codes
vary from area to area and it is your responsibility to determine which codes should be followed,
and to verify that the equipment, installation, and operation are in compliance with the latest
revision of these codes.
Equipment damage or serious injury to personnel can result from the failure to follow all applicable
codes and standards. We do not guarantee the products described in this publication are suitable
for your particular application, nor do we assume any responsibility for your product design,
installation, or operation.
If you have any questions concerning the installation or operation of this equipment, or if you
need additional information, please call us at 1-800-633-0405 or 770-844-4200.This publication is
based on information that was available at the time it was printed. At Automationdirect.com® we

AutomationDirect’s SOLO Modular units are a single loop temperature controller that can
control heating or cooling processes. Depending upon the particular model of controller, the
available outputs include relay, voltage pulse, linear voltage, or current. Available with twelve
selectable alarm types. SOLO Modular controllers have two control outputs that can be used
for control of a heating or cooling applications, alarm output, or for retransmitting the process
variable. Using both outputs for control output allows for both heating and cooling control or
two stage heating or two stage cooling control. There are four types of control modes: PID,
ON/OFF, RAMP/SOAK and Manual. SOLO Modular can accept various types of thermocouple
and RTDs as well as 0-10V or 4-20 mA anaolog input signals.
Other features include:
•Auto Tuning (AT) function with PID control
•DIN rail mountable
•LEDs for indication and diagnostics
•Easy conguration using SL-SOFT SOLO conguration software or Modbus
communications
•Selectable between °C and °F
•cULus and CE agency approvals

second. See table below for LED values.
3. RUN LED is on when the controller is active.
4. ERROR LED is on when errors occur in input, memory or communication.
5. When an output is active, its corresponding output LED will be on.
6. AT LED ashes when PID parameters are being auto-tuned.
7. RX LED ashes when SLM receives communication signals. TX LED ashes when SLM sends out
communication signals. Communication protocol displayed on the LEDs after the power to the SLM
is switched on:
WARNING! ELECTRIC SHOCK DANGER
To prevent electric shock, do not connect AC
power to your device until all input and output
connections are completed.
