OMR card - IN.03

IN.03 - 4x Input for Pt/Ni/Cu sensors

Plug-in card for measuring resistance sensors is fully isolated from the internal bus with a galvanic isolation also between individual outputs.
The design of the cards allows their use at any position in the device. If during the use of the device appear new requirements to increase the number of inputs or outputs, just order another card and insert it into a free slot. In this manner the device can "grow" with your requirements.
