    Overview Overview Structure and function With the universal transmitter DIQ/S 181, one digital sensor can be operated. The universal transmitter has three relay outputs and two current outputs to be connected to existing process control systems. The universal transmitter DIQ/S 181 serves as a terminal and controller in the system 181.
