Cable lengths
The resistance of the connection cables causes a voltage drop along the cable. The extent of the power
drop depends on the cable length and the current passing through the cable. The voltage at the last
device in a supply chain must be within the specified voltage range (6 V or higher). The data shown in
Tab. 4-4 is based on the assumption that the ECAT STGMM 6 measurement modules are operated
under load. A 350
full bridge is connected to each measurement channel, each supplied with a 5 V
bridge supply voltage. This results in a power consumption of typ. 3 W per module.

Tab. 4-4: Maximum number of measurement modules (depending on cable length / supply voltage)
If more measurement modules are wired in series (given the same cable length and supply voltage)
than stated in Tab. 4-4, an additional power supply is needed. An intermediate power supply is also
needed if the ECAT STGMM 6 measurement modules connected require more current (due to increased
sensor excitation) than the power supply available is able to deliver.
For additional technical information on the topic “Daisy-chaining of measure-
ment modules under load”, please contact the CSM sales department.
Specific information on the cables available can be found in the datasheet.
See data sheet “CSM MiniModule Accessories”.
