DCT 561

BD Sensors DCT 561 Digital Pressure Transmitter with RS485 Modbus RTU, With Ceramic Sensor accuracy according to IEC 60770: 0.5 % FSO Nominal pressure from 0 … 600 mbar up to 0 … 600 bar

SKU: DCT 561 Category:

The DCT 561 with RS485 interface uses thecommunication protocol Modbus RTU which has found the way in industrial communication as an open protocol. The Modbus protocol is based on a master slave architecture with which up to 247 slaves can be questioned by a master – the data will transfer in binary form. The sensor technology of the DCT 561 is the same as those of the proven pressure transmitter DMK 331, whereby the DCT 561 is suitable for pasty, polluted and aggressive media as well as for low-pressure oxygen applications. The modular concept of the pressure transmitter allows customized electrical or mechanical connections, so it is easy to adapt the DCT 561 to different conditions on-site. Areas of use include plant and machine engineering environmental engineering (water - sewage - recycling) & medical technology.
