SYL-2381-SSR PID TEMPERATURE CONTROLLER
INSTRUCTION MANUAL
Version 1.0 (Feb, 2018)
Caution
• This controller is intended to control equipment under normal operating
conditions. If failure or malfunction of it could lead to an abnormal operating
condition that could cause personal injury or damage to the equipment or other
property, other devices (limit or safety controls) or systems (alarm or
supervisory) intended to warn of or protect against failure or malfunction of the
controller must be incorporated into and maintained as part of the control
system.
• Installing the rubber gasket supplied will protect the controller front panel from
dust and water splash (IP54 rating). Additional protection is needed for higher
IP rating.
• This controller carries a 90-day warranty. This warranty is limited to the
controller only.

4.1 Sensor connection
4.1.1 Thermocouple
The thermocouple should be connected to terminals 9 and 10. Make sure that
polarity is correct. There are two commonly used color codes for the K type
thermocouple. US color code uses yellow (positive) and red (negative). Imported
DIN color code uses red (positive) and green/blue (negative). The temperature
reading will decrease as temperature increases if the connection is reversed.
4.1.2 RTD sensor
For a three-wire RTD with standard DIN color code, the two red wires should be
connected to the terminals 9 and 10. The white wire should be connected to
terminal 8. For a two-wire RTD, the wires should be connected to terminals 8 and
9. Jump a wire between terminals 9 and 10.
For PT100 sensor, set Input Sensor Type, Inty, to “P100” (1 degree resolution)
or “P10.0” (0.1 degree resolution).
4.2 Power to the controller
The power cables should be connected to terminals 1 and 2. Polarity does not
matter. It can be powered by 85 - 260 V AC or DC power source. Neither a
transformer nor jumper is needed to wire it up. For the sake of consistency with
the wiring example described later, we suggest you connect the hot wire to
terminal 2 and neutral to 1. Since the controller is in a plastic shell, ground wire is
unnecessary.
4.3 Output connection
Three control output options are offered by this controller: (1) The SSR control
output provides an 6V DC signal. (2) J1 relay output can be used to turn on a
contactor or a solenoid valve. It can also drive a small heater directly if the heater
draws less 3 Ampere.
4.3.1 Connecting the load through SSR
Connect terminal 7 to the negative input and terminal 6 to the positive input of the
SSR. Set the Control Output Mode (outy) to 1, 2, or 5 depending on the control
mode to be used. Then set the Main Output Mode (Coty) to “SSR”. See Figure
11 for an example. Please note that the “0-20” or “4-20” options are not available
on this model.
4.3.2 Drive the load through J1 relay
Assuming the controller is powered by a 120 V AC source and the contactor has
a 120 V AC coil, jump a wire between terminal 2 and 4. Connect terminal 5 to one
lead of the coil and terminal 1 to the other lead of the coil. Set the system Control
Output Mode (outy) to 3 or 4 depending on the control mode to be used. Please
see Figure 10 for an example.
4.4 Note for first time users
For first time users with no prior experience with PID controllers, the
following notes may prevent you from making a few common mistakes.
4.4.1 Power to the heater does not flow through terminal 4 and 5 of the controller.
The controller consumes less than 2 watts of power. It only provides a control
signal to the relay. Therefore, 20 gauge wires are sufficient for providing power to
terminal 1 and 2. Thicker wires may be more difficult to install.
4.4.2 The J1 relay is “dry single pole switch”. It does not provide power by itself.
Figure 10 shows how the J1 relay is wired to pass the 120 V AC power to drive an
external contactor which requires 120 V AC for its coil. If the coil of the contactor
requires a different voltage than the power supplied to the controller, an additional
power source will be needed.
4.4.3 SSR output power does not come from the input of the SSR. The output of
the SSR is a single pole switch between terminal 1 and 2 of the SSR. The input of
the SSR is for control, or triggering, the SSR. (Please note we are talking about
the SSR itself, not the SSR control output of the controller). Figure 11 shows how
the SSR output should be wired. When switching a North American 240VAC power,
the heater will be live even when the SSR is off. Users should install a double pole
mechanical switch to the power input.
5. Parameter Settings
For safety reasons, control parameters are divided into three groups with different
pass codes. You should only give the code to those who have the responsibility
and knowledge of how to properly change it. Code 0089 contains parameters for
system configuration that may need to be changed during the initial set up. Code
0036 contains parameters for tuning the control performance. Code 0001 is for
changing set temperature and alarm settings.
5.1 System configuration parameters (accessed by code 0089)
The system configuration parameters are listed in Table 1. To change the
parameters, press SET key briefly, enter the code “0089” and press SET key
again. The procedures to change system parameters are shown in the flow chart
in Figure 3.
