KJ2201X1-HA1智能逻辑终端块 英文介绍
1、 Product positioning
This terminal block belongs to the field wiring interface unit, installed in the control cabinet or safety system rack, used to reliably connect the signals of field instruments (such as pressure transmitters, temperature transmitters, switch devices, etc.) to the logic control module or safety solver.
The "HA" in the model generally indicates that it is suitable for hazardous area environments.
2、 Main functions
Signal wiring transition: achieve safe electrical connection between on-site equipment and control system.
Suitable for hazardous areas: meet the requirements of explosion-proof and intrinsic safety system applications.
Channel isolation design: reduce on-site interference and improve system stability.
Standard terminal structure: Supports screw crimping or spring terminal methods for easy maintenance.
3、 Technical features
Suitable for low-voltage DC signal systems
Industrial grade wide temperature design (suitable for harsh environments)
DIN rail installation structure
Strong resistance to vibration and impact
Compact structure, clear wiring
4、 Typical application industries
Oil and Natural Gas
Chemical production equipment
Power and Energy Systems
Offshore platform and hazardous environment control system
5、 System Function Description
In the control system architecture, KJ2201X1-HA1 does not directly perform logical operations, but serves as a "bridge" between logical modules and field devices. It ensures that the signal has stable, safe, and standardized connection conditions before entering the control core, and is an important basic component for the reliable operation of the system.
