The Cell-PDA module allows an external differential voltage to be measured and recorded simultaneously with the primary signal, without the need for a peripheral port. This brings extra functionality to instruments such as the dModules in the Ivium-n-Stat and the pocketSTAT2/Vertex.One/Vertex.C.

The module connects between the instrument and the cell cable. Screw contacts then allow the connection of wires between the cell and the + and – terminals. The voltage is automatically recorded on the analog input 1 channel.

Technical specifications

• Powered from the cell connector
• Measurement range is up to ±10V between the + and – inputs
• Common mode voltage is ±12V, i.e. potential of the inputs can be max. 12V different from the instrument ground (Agnd)
• The voltage signal transfers to analog input1 of the potentiostat cell connector
• Each input has a very high input impedance >10^12 Ohm
• Not suitable for connection of thermocouples
