SYL-2381-mA PID TEMPERATURE CONTROLLER
INSTRUCTION MANUAL
Version 1.3 (May, 2021)
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.
1. Features
•
The PID control with artificial intelligent enhancement for precision temperature
control.
•
Auto-tuning function can find the best PID parameter automatically.
•
ON/OFF control mode for refrigerator, motor and solenoid valve control
application.
•
Linear output control 0 ~ 20 mA or 4 ~ 20 mA.
•
Bumpless transfer between Auto and Manual control mode.
•
Optional serial communication port (RS-485/Modbus_RTU).
•
The output can be set for linear output controller or relay contactor control by
the user.
•
Support 10 different types of commonly used temperature sensor inputs.

①
AL1: Relay J1 output indicator.
AT: ON for manual mode. Blinking during auto-tuning process.
OUT: main output indicator.
②
Up key: value increment / select the next parameter.
③
Down key: value decrement / select previous parameter.
④
Shift key: start auto tuning / shift digit / check output percentage*
⑤
Set key: confirm change / switch between Manual and Auto mode.
⑥
PV window: measured temperature, or, Process Value (PV)
⑦
SV window: set temperature, or, Set Value (SV)
Note *: Press Shift key momentarily to change the SV window from set
temperature to real-time output percentage. It will be
display as “
o
X
XX”.
For
example,
“
o 90
” means
the current output percentage is 90%. Press Shift key
again to switch back to set temperature.
