QT120-INEPC control board
Main features
1. Password protection function: ·The user can set a password to protect the important parameters of the actuator from being arbitrarily modified to ensure the safety of valve control. Generally, the password is entered when using it for the first time.
2. Handwheel/electric control switching: ·The clutch system is used to realize automatic switching between handwheel drive and motor drive, with high transmission efficiency and easy use.
3. Control mode: ·According to on-site debugging and control needs, three modes: local control, remote operation, and stop can be selected. Under local control, it can also be controlled by knob or remote control.
4. Isolation protection: Both input and output channels adopt photoelectric isolation and have 2.5KVrms high voltage protection function. Anti-surge protection is adopted to achieve electrical separation within the actuator and has good anti-interference performance.
5. Valve jam protection: ·When the actuator cannot overcome the torque required by the valve and becomes jammed, the circuit will disconnect the corresponding contacts, forcibly terminate the operation of the actuator, and at the same time send an alarm signal to the remote control device.
Ordering instructions
1. The wiring harness from the remote control, module to terminal block is standard.
2. Configuration of part-turn actuator: module + single-turn potentiometer (encoder) + gear plate Configuration of multi-turn actuator: module + multi-turn potentiometer (encoder) + intelligent actuator
3. High power The size of the AC contactor connected to the actuator is determined by the motor power.
4. The Z180 actuator requires an external intermediate adapter plate. Other special voltages and requirements must be notified in advance when ordering.
1. Product working temperature: -20~70C Storage temperature: -40~85C
2. Input signal: 4~20mA, impedance: 250 ohms. Output signal: 4~20mA, load: 750 ohm
3. Basic error: ±1%, dead zone: 0.5%~10% continuously adjustable, hysteresis: ±1%.
4. The on-off type and the modulating type are integrated, and the operation can be switched through the software password.
5 Full Chinese display and intuitive operation of Chinese character menu.
6. Automatic phase commutation and phase loss protection.
7. Three operating modes: on-site/remote/remote control. On-site operation adopts a rotary structure.
8. Four-way relay configuration output, each group of relays has two outputs, one open and one closed. The maximum resistive load is 5A250VAC
9. Three angle detection methods can be selected: single-turn potentiometer, multi-turn potentiometer, and absolute value encoder.
10. Comprehensive fault alarms such as motor overheating, instantaneous reversal, power outage, overload, etc.
11. Signal interruption protection function. Sensor failure protection.
12. The position after losing the new position can be set: fully open, fully closed, and guaranteed position.
13. Motor running times are saved and timely queried when the power is off.
14. Both input and output current can be calibrated and calibrated through the menu
15. Fieldbus function ·Customers can choose RS485 industrial bus communication interface, Modbus RTU and Profibus DP communication protocols. Other communication interfaces and protocols can also be designed according to customer requirements.
