Series Temperature Controller 

Instruction Sheet 

Thank you very much for choosing Delta DTE series temperature controller. Please read this instruction sheet carefully before 
using your DTE to ensure proper operation. Keep this instruction sheet handy for quick reference. 

 Warning 

DANGER! CAUTION! ELECTRIC SHOCK! 

DTE is an OPEN-TYPE device and therefore should be installed in an enclosure free of airborne dust, 
humidity, electric shock and vibration. The enclosure should prevent non-maintenance staff from 
operating the device (e.g. key or specific tools are required for opening the enclosure) in case danger and 
damage on the device may occur

.

1.  Prevent dust or metallic debris from falling into the device and cause malfunctions. 

DO NOT

 modify or uninstall the circuit 

board of DTE without being permitted. 

DO NOT

 use empty terminals. 

2.  Keep away from high-voltage and high-frequency environment during the installation in case of interference. Prevent using 

the device in premises which contain:   

(a) dust or corrosive gas;    (b) high humidity and high radiation;    (c) shock and vibration. 

3.  The power has to be switched off when wiring or changing the temperature sensor. 

4.  When installing the circuit board of the accessory, please make sure the power of the main unit is switched off and insert 

the accessory into the correct slot on the main unit. 

5.  Make sure to use compensation wire which matches the thermocouple or platinum resistance when extending or 

connecting the thermocouple or platinum resistance. 

6.  Keep the wire as short as possible when wiring a sensor to the controller. Separate the power cable and load wire in order 

to prevent interference and induced noise. 

7.  Make sure the power cables and signal device are installed correctly before switching on the power; otherwise serious 

damage may occur. 

8.

DO NOT

 touch the terminal or repair the device when the power is on; otherwise an electric shock may occur.   

9.  Please wait for 1 minute after the power is switched off to allow the capacitor to discharge and 

DO NOT

 touch the internal 

wiring within this period.   

10.

DO NOT

 touch the internal terminal when DTE is either switched on or off in case you may damage the circuit. 

11. Please place DTE with other heating objects (e.g. power supply) within proper distance while installing DTE.

Note:

 The default setting in DTE10T is “thermocouple K type”. The default setting in DTE10P is “Pt100".   

Communication address: Input sensor types at H10A0 ~ H10A7; input upper limits at H1010 ~ H1017; input lower limits at 
H1018 ~ H101F.

 Output

DTE supports maximum 16 channels of outputs, belonging to output groups OUT1, OUT2, SUB1 and SUB2, each group with 4 
channels. See the explanations below for how input channels correspond to output groups. 

 Without group INB (4 channels of input): Every channel corresponds to 2 groups of output and 2 groups of alarms. OUT1 and 

SUB1 are for control output, and OUT1 can be used for proportional output. OUT2 and SUB2 are fixed for alarm output.   

 With group INB (8 channels of input): Every channel is paired with 2 groups of outputs. OUT1 and OUT2 are used for control 

output or proportional output of CH1 ~ CH8. SUB1 and SUB2 are used for control output or alarm output. 

See Table 1 for the relations between input and output.

When there are only 4 channels of inputs, OUT2 and SUB2 cannot be set up by the user but set up automatically as "alarm 

output” by the controller.

Control Output: 

DTE offers PID control, ON/OFF control, manual control and programmable PID control. Control output methods are set at 
address H10B8 ~ H10BF (default = 0: PID), PID parameters at H1028 ~ H105F, ON/OFF parameters at H1058 ~ H106F, and 
manual control parameters at H1070 ~ H107F.   

Alarm Output: 

DTE offers 12 alarm modes. The alarm modes are set up at address H10C0 ~ H10C7, upper limits at H1080 ~ H1087 and 
lower limits at H1088 ~ H108F.

 Synchronous Communication Protocol & Auto ID Setup

This function allows the auto setup of communication protocol in extension module DTC2000 and DTC2001 following the 
communication protocol set in the DTE main unit. The station IDs of DTC decrease. See below for the steps. 

1.  Set the auto communication ID of DTE as “1” (communication address: H10F8). 

2.  Switch off DTE. Connect DTE with extension module DTC2000, DTC2001 and switch on DTE again. 

3.  Default communication protocol: 9,600bps, 7 bits, Even, 1 stop bit, communication address = 01.
