pressure transmitter DCT 561 | RS485 Modbus
digital pressure transmitter DCT561

DCT 561

pressure sensor: ceramic
with RS485 Modbus RTU

The DCT 561 with RS485 interface uses the communication protocol Mudbugs RTU which has found the way in industrial communication as an open protocol. The Mudbugs 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 almost every industrial application, if medium is compatible with stainless steel 316L and ceramics.

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.
