Pfeiffer Vacuum DigiLine™

DigiLine sensors are supplied with 24 VDC. The measured values are output via an RS-232 or RS 485 digital interface. The various application options are described in Figure 3.9.

Individual transmitters can be operated and their measured values displayed by means of the DPG 101 controller. The DPG 109 can supply up to nine transmitters Transmitter signals can also be directly displayed and processed on a PC or PLC by means of the DokuStar Plus software. With the aid of converters, the RS-485 signal can be converted to a fieldbus signal (Profibus-DP or DeviceNet), thus enabling it to be used in plant control systems with a fieldbus controller that enables especially simple and cost-effective cabling.
