DCT 561 Industrial Pressure Transmitter with RS485 Modbus RTU Ceramic Sensor accuracy according to IEC 60770: 0.5 % FSO Nominal pressure The DCT 561 with RS485 interface uses the communication 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. from 0 ... 600 mbar up to 0 ... 600 bar Output signal RS485 with Modbus RTU protocol Special characteristic ► good thermal behaviour 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. good long term stability 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. pressure port G 1/2" open port PVDF for aggressive media (up to 60 bar) oxygen application Preferred areas of use are Plant and machine engineering Environmental engineering (water - sewage - recycling) Medical technology BD SENSORS GmbH BD-Sensors-Straße 1 D - 95199 Thierstein www.bdsensors.com info@bdse
