• Measuring Range
K(-50 to 1300°C),S(-50 to 1700°C),R(-50 to 1650°C),T(-200 to 350°C),E(0-800°C),J(0-1000°C) 6(0-1800°C),N(0-1300°C),Cu50(-50 to 150°C),Pt100(-200 to +600°C)
Linear input: defined by user, range(-1999 to 9999)
• Measuring accuracy
0.2%FS+0.1°C (Cu50 copper resistor compensation or ice point compensation)
0.2%FS+0.2°C (TC input and internal compenstation)
• Resolution
0.1°C or 1°C selectable (Automatically change to 1°C when the temperature is high than 999.9°C)
• Control Mode
on/off control mode(deadband adjustable)
Al MPT with auto tuning,adopting fuzzy logic PID algorithm
• Auto/Manual bumpless transfer
Be able to switch between manual and auto control from front panel
• Soft Start function
In some particular application, the output is not allowed to be at its 100%, otherwise the system will be damaged, controller offers a soft start solution
• Dual Setpoint with remote selection
In some application, dual setpoints is necessarily to have, this controller offers a solution to have dual setpoints and be able to switch between each other via an on/off switch which connected to terminal of this controller.
• Alarm standby fucntion
Under some very specific circumstance, the whole system is working perfectly normal, but the condition that will trigger the alarm is accordant. therefore the alarm should go off while actually the whole system is no problem. this alarm could lead to mis-operation. In a simple heating application, when set the controller as deviation low limit alarm, at the point when power just turned on, the alarm should go off as the condition is matched, but the heating system is no problem, the deviation low limit alarm will be blocked at this case.
• RS-485 communication
Be able to communication with PC or other device with RS-485 communication.
• Time proportional output control
Controller has a features to implement a time proportion output, for example, in a relay output application, if the cycle time is 20S, user can define the on/off time of the relay, user can set the on time as 40%, off time as 60%. which means in every circle, the relay will be at on status for 8 seconds and at off status for 12 seconds.
• PV Re-transmission output
The Process value can be retransmitted and output as linear current, the range of the linear current is configurable, could be 4-20mA, could be 0-10mA.
• Remote SV
The setting value can defined by remote linear voltage signal, such as 1-5V
1.The maximum segments can be programmed to the profile is 50 segments
2.Event output available(Event is a pulse signal last for 0.5 seconds). event output can make this controller interact with other device, such as open a value, trigger a timer etc.
3.Multiple profile can be programmed, depends on different products, user can choose to perform which profile
4.Various shortcut key on the front panel which can "run" "hold" "stop" the program via set key on front panel
5.Flexible program, the basic status like "Run" "hold" "Stop" can be programed into the profile.
6.The unique "jump" function can make the controller jump to different segments and be able to implement a circle control.
7.The alarm can be triggered by configuring the program
8.Event input function offers a option to "run" "stop" "hold" the program with a on/off switch and the on/off switch will be connected to the terminal of controller.
9.PV startup and PV preparation will ensure the integrity of the control
10.Various options offered if the controller experience a sudden power cut and power resume incident
