Cleanroom personnel are an important source of cleanroom contamination. To ensure the cleanliness of the cleanroom, in addition to high-quality hardware, a well-designed personnel access control system is also required to guarantee full control of all access attempts. The ICP DAS WISE controller is perfect for managing access control and enables remote monitoring and control of all access attempts to the cleanroom in real time.
The ICP DAS WISE-7144 is equipped with 8 DI and 8 DO, providing integration with various devices for receiving or sending digital signals. The Logic Rule Engine on the WISE controller enables easy configuration for various management processes.
For example, when connecting the WISE-7144 with an IP Camera for access control, it allows the IP Camera (via CGI command sending) to record real-time images of the workers before opening the outer door to the clean zone.
After the outer door is shut, the workers enter the clean zone and move into the air shower chamber. At this time, the WISE-7144 is able to start the air shower; the built-in Timer function makes it easy to define the shower time interval.
After the shower is complete, the inner door opens for the workers to move from the clean zone into the cleanroom. At the same time, the WISE-7144 can connect to a positive-pressure sensor and the access control security system for monitoring all access attempts and managing the space.
The WISE-7144 also supports the Modbus TCP interface, allowing information to be instantly transmitted to the control center, enabling real-time monitoring of the overall status of the cleanroom more efficiently.
-Logic Rule Engine: The WISE controller features an IF-THEN-ELSE logic rule engine that enables logic configuration via a web page in just a few clicks — no programming required.
-Modbus TCP Support: Supports the Modbus TCP protocol, enabling seamless integration with SCADA software.
-Power over Ethernet (PoE): The WISE-7144 features PoE, eliminating the need for dedicated electrical outlets and reducing complicated wiring. With a PoE switch, it allows both power and data to be transmitted over a single Ethernet cable.
-Timer Function: The built-in timer function enables evaluation of timeout conditions and allows you to start or stop the timer as needed.
-CGI Command Function: The WISE-7144 supports CGI commands, allowing it to send CGI instructions in response to specific events to enable process execution on remote controllers, such as IP cameras.
