PLATINUM^TM Series Universal Benchtop Digital Controllers

Descrição

The OMEGA™ CS8DPt is a portable benchtop digital controller and with a large color-changing display. This benchtop controller features the LED displays that can be programmed to change color between Green, Amber, and Red at any setpoint or alarm point. Other options include, serial communications, Modbus^®, and Ethernet.

This universal temperature and process instrument handles 10 common types of thermocouples, multiple RTDs, and several process (DC) voltage & current ranges, and strain type of inputs.

Embedded Internet
The OMEGA™ Cs8DPt controllers with fully loaded communication options can connect directly to an Ethernet network with a standard RJ45 connector and can send and receive data in standard TCP/IP packets.

This series devices can serve Web pages over an Ethernet LAN or even over the Internet, making it possible to monitor and control a process through a Web browser (such as Microsoft Internet Explorer®) from anywhere in the facility or anywhere in the world.

Remote Control
For example, using an CS8DPt Series temperature controller to control a heater, an engineer can monitor the temperature, change setpoints or alarm points, turn the heater on and off, or make other modifications from anywhere on the local network or anywhere on the Internet. The Web pages are easily customized, and secure, password protected access to the devices is easily controlled. And it requires absolutely no special software on the engineer’s computer to view the data and “supervise” the controller— nothing other than a Web browser.

E-Mail and Alarm
In fact, the Cs8DPt controller can even send an e-mail to the engineer (or anyone he or she chooses) about an alarm condition or to update the status. Leveraging the technology of the Internet, the engineer could receive a message from the controller on an Internet-enabled pager or cell phone.

Most remarkable is that all this can be accomplished without a computer. The OMEGA™ CS8DPt controller with fully loaded communication options connects directly to the Ethernet network—not to the serial port of a computer functioning as a “server” and “master” to “slave” instruments connected through serial communications. With the loaded C24 option, these devices are also available with RS232 and RS485, and MODBUS serial communications.
