Temperature Controllers
Self-correction function
Heating / cooling control
Large-screen LED display
Temperature alarm
Input:
a) Thermocouple: K , J, R, S , B , E , T , N ( JIS/IEC) , PL11 (NBS) W5Re/ W26Re (ASTM)
b) Resistance Temperature Detector (RTD) : Pt100(JIS/IEC),JPt100(JIS)
c) DC Input ; DC0-5V , DC1-5V , DC0-20mA＊,DC4-20mA＊ ＊For DC current input ,connect a 250 Ωresister to the input terminals. *input display accuracy: (0 .3 % of reading + 1 digit)
Process value bias
Temperature input :- 1999(-199.9) to 9999(999.9)℃ [°F ] DC Voltage, DC current： - span to + span
Set range
a. set value :same as input range
b. heat of side proportion band : 1 to span or0.1 to span (temperature input)*1，0.1to 100.0% of span(voltageinput)
c .refrigeration side of proportion band: heat side of proportion1—1000%
d. integral time :1—3600sec * 2
e. differential time : 1—3600sec * 3
f. anti-reset windup (ARW): 1—100% * 4 of proportion band
g .heat side of proportion cycletime: 1—100sec *5
h. refrigeration side of proportion cycle time:1—100sec * 6
I. dead band: - 10 –10 or -10.0 --+10.0 ℃ [ ℉ ] (temperature input) ,span – 10.0--- +10.0% (Voltage /current input )* 7
1. if set proportion band as 0 ℃ [ ℉ ] ,it turns to “ON – OFF action”
2. if set integral time as 0 sec ,it turns to “PD action”
3. if set differential time as “0 sec” ,it turns to “PI action”
4. if set anti-reset windup as “0%” .D action turns to “OFF”
5. it needs not to set cycle time when current output
6. if we don’t set the dead band as “negative” ,it turns to “superpose” Controller action
PID control ( 0N – OFF ,P ,PI ,PD control )
a .automative perform function
　　1 adjust-self method: limit period way
　　2 AT period: 1.5
b automative emendation,when settingchanges, correction-self will be found, Except of heating / cooling PID control action
Control output
a relay contact output .form A contact 250VAC 3A (resistive load ) Electrical pattern: more than 300,000 times, rated load.
b voltage pulse output 0 -12 VDC ( load resistance ; more than 600Ω
c current output :4 to 20mACD ( load resistance ; less than 600 Ω)
Temperature alarm
　　Alarm points:two alarm
　　Type: deviation high alarm, deviation low alarm, deviation high/low alarm, Band alarm. Process high alarm , Process low alarm. Set value high alarm, Set value low alarm It can choose hold function (except for alarm setting value)
Alarm output
　　Relay contact output .form A contact 250VAC 1A (resistive load) Switching than over 50000
　　Control Loop break alarm output need choosing one in ALM1 or ALM2.
　　When Control Loop break alarm has been selected, another alarm can not be set to LBA.
