 Precaution
Warning! Please comply with safety precautions in the manual. Failure to do so may cause controller or peripheral products
malfunction, or even result in serious harm such as fire, electrical injury or other damages.
DANGER! Caution! Electric Shock! Do not touch the AC terminals while the power is supplied to the controller to prevent electric
shock. Make sure power is disconnected while checking the unit inside.
This controller is an open-type temperature controller. Be sure to evaluate any dangerous application in which a serious human
injury or serious property damage may occur.
This controller is not furnished with a power switch or fuse, therefore a switch or circuit-breaker should be provided in the
application system including this unit. The switch or circuit-breaker should be nearby and easily reached by operator, and must
have the mark disconnecting means for this unit.
1. Always use recommended solder-less terminals: Fork terminal with isolation (M3 screw, width is 5.8 mm). Make sure all wires are
connected to the correct polarity of terminals.
2. Do not allow dust or foreign objects to fall inside the controller to prevent it from malfunctioning. Never modify or disassemble the
controller. Do not connect anything to the "No used" terminals.
3. To prevent interference, keep away from high voltage and high frequency when installing. Do not install and/or use the controller in
places subject to:
(a) Dust or corrosive gases and liquid; (b) High humidity and high radiation; (c) Vibration and shock;
4. Power must be off when wiring and replacing a temperature sensor.
5. Be sure to use compensating wires that match the thermocouple types when extending or connecting the thermocouple wires.
6. Please use wires with resistance when extending or connecting a platinum resistance thermometer (RTD).
7. Please keep the wire as short as possible when wiring a platinum resistance thermometer (RTD) to the controller and please route
power wires as far as possible from load wires to prevent interference and induced noise.
8. 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.
9. Make sure power cables and signals from instruments are all installed properly before energizing the controller, otherwise serious
damage may occur.
10. Do not touch the terminals in the controller or try to repair the controller when power is on, in order to prevent electric shock.
11. Wait at least one minute after power is disconnected to allow capacitors to discharge, and please do not touch any internal circuit
within this period.
12. When maintaining the controller, please turn off the power first and use a dry cloth to clean the surface. Do not open the enclosure or
touch the internal circuit to avoid circuit destruction or malfunction.
13. Do not use any sharp objects to press the operation buttons. It may result in button surface damage or even electrical injury when
accidentally access to internal circuit.
14. Use copper conductors only.
 Product Features
DTI series is a new temperature controller with a high cost-performance ratio. It greatly decreases development costs and time, and
improves the functions of temperature control systems. With a length of only 60mm and high resolution LCD display, it is easy for
operators to monitor the temperatures of any environment or occasion.
 High resolution LCD panel: High contrast and customized display graphics for user’s easy understanding.
 High-speed sampling time 100ms: High-speed sampling for external temperature measurement and fast output response for
performance requirements of high-precision control.
 Shortened length to 60mm: Shorten the length of the controller to reduce the installation space.
 Conform with CE international safety certification
