2.2 Device description
The signal converter is able to measure different parameters in liquids and fluids which are
common in the water and waste water industry. It has three freely programmable current
outputs and optionally three mechanical relays which can be configured as alarm or status
relays or limit switches.
The manufacturer offers the device as a one channel version and a version with two channels.
The last one possesses two sensor inputs for using sensors with different measuring principles
as they are:
• Amperometric measurements (disinfection parameters, dissolved oxygen)
• Potentiometric measurements (pH / ORP)
• Conductive measurements (conductive / inductive)
When ordering the one channel version, only the interface "Pos.A" is populated. In the version
with two channels the interfaces "Pos.A" and "Pos.B" are populated (for further information
refer to
Overview of the terminal compartment on page 22):
