LCD Display PID Regulator Controller
-Key features
● Flagship product, LCD display PID Temperature Controller
● TC/RTD input by default, analog needs to be specified when order
● Output field selectable(Relay+SSR Drive) output
● Parameter restore to factory default setting
● 1 alarm as standard, maximum 2 alarms available
● 85~265Vac or 24vdc/ac source
● Auto/manual control bumpless transfer
● Output bar graphic and digital display
● RS-485 communication optional
● Customized quick start menu, you can put parameters on the quick start menu for easy access and lock other parameters from unauthorized access
● RUN/STOP function from local controller or remotely from HMI via RS-485
● Relay output for alarm can be configured as NO to NC or NC to NO
● Setting value(SV) minimum and maximum configurable, to prevent the SV being set at a dangerous value
● Output minimum and maximum configurable, the factory default output is 0%~100%, you can set the output as 30%~100%, by doing this, the output will be not less than 30% regardless of the input
● The control mode of the controller right after power on can be set as auto control mode, Stop mode or manual control mode.
● When setting value(SV) of the controller configured via master device such as HMI, the SV can be stored in EEPROM or RAM
● The data format for communication can be configured as 8N1, 8O1,or 8E1
8 data bytes, No parity, 1 stop byte(8,N,1)
8 data bytes, Odd parity, 1 stop byte(8,O,1)
8 data bytes, Even parity, 1 stop byte(8,E,1)
-Auto/manual control bumpless transfer
Click A/M key on the front plate, you can switch from auto control mode to manual control mode, back and forth anytime you want,this is a very useful features for application where the power needs to be manually controlled
-Relay+SSR Drive output field selectable
One controller comes with both Relay and SSR Drive output, customer can field select the output
-Parameter restore to factory settings
Controller with a lot of parameters, customer may get lost when programming the controller, this feature will take the customer back to ground zero
-Output digital display and bargrahic display
The output 0%~100% is displayed via bar graphic and digital dispaly(0%~100%)
-RS-485 communication
Isolated RS-485 communication makes this controller is ideal for system intergration
-Customized quick start menu
Parameters can be distributed to quick start menu for easy access and some of critical parameters can be locked from unauthorized access
-RUN/STOP feature locally and remotely via RS-485
It's possible to RUN/STOP the controller from the unit itself or via RS-485 remotely from HMI.
-Alarm relay NO to NC or NC to NO programmable
For most of controller, the relay will go from NO to NC when alarm triggered, it's possible to program the relay for alarm to stay at NC instead of NO , and change from NC to NO when alarm triggered. alarm can be used as limit control to cut off the supply of the system when over temperature happens
-Output high/low limit and Setting value high/low limit configurable
Output is 0%~100% by default but you can configure it as other range to always have minimum output or never let the output higher than certain value, setting value high/low range configurable makes it safe to use in field applcation.
