    PID-4CH-SSR      Multi-Loop Controller Instruction Manual 

 

1. Features: 

1.1. 4 channels of temperature controls up to 4 channels in a compact 1/4 DIN size. 

4 kinds of combinations of temperature set value, PID constant, alarm set value, etc. 

1.1.Input Sensor Types 
Thermocouple (temperature input): K, J, T, E, S 
Resistance thermometer (temperature input): Pt100, CU50 
1.2.Control Outputs 
    A control output can be a relay output, voltage output (for driving SSR), or current output, depending on 

the model. 

1.3.Adjusting PID Constants 

Can be easily set the optimum PID constants by performing AT (auto-tuning) with the limit cycle method. 

1.4.Standard Alarms 

Can be output an alarm when the deviation, process value, set point, or manipulated value reaches a 

specified value. 

    1.5 Sampling Time: 2 sec 

1.6.Use this controller within the following allowable range: 

Allowable ambient temperature: −0 to +55 °C 
Allowable ambient humidity:    5 to 85 % RH. 

2. Dimensions: 

h×w×d(Unit: mm) 96×96×112 Panel cutout 92×92 

3. Parts Description: 

 

1 ALM:

 lamp Lights when Event occurs 

2 Output lamp: 

Lights when output    is turned on 

3 Channel key: 

You can press ‘CH1~4’ for 3 seconds to enter into 

corresponding channel menu.   

4 PV display:

   

Displays Measured value (PV)   

5

 

Up key:

   

Increase numerals.   

6 Down key:

   

Decrease numerals 

7Shift key:

 

Shift digits when settings are changed.

 

8 Set (SET) key:

 

Used for parameter calling up and set 

value registration.
