DS Tacho1 Supply Voltage

DS-Tacho1 is a nice hardware for inductive sensor signal conditioning and we want to use it also with counter inputs from other vendors.

Must the supply voltage on Lemo PIN5 (see attachment) be exactly 5V or is there a tolerance?

The measurement system we want to use has only one global supply voltage an we need to set it to 10V (to supply pressure sensors)

- so do we have to use a DC/DC converter for the DS-Tacho1 to work?

Dear Stefan,


the 10V global supply voltage won't be a problem, because the Tacho1 has a wide max input voltage range.



All data about the Tacho1 can be found in in the manual which is on our page.


Best regards.

Hello Rok,

the speed sensor is conectet to the DS-Tacho1 via the Sub-D input and that's not what i asked.

I want tho know what's the max. tolerable supply voltage (it comes from the measurement system on Lemo PIN5)

for the DS-Tachos internal electronic circuit.

I can't find data about this in the DS-Tacho1 manual, just the picture i've attached above..
