MIO

The MIO card is a member of the extension card family available for the Zahner IM7/x potentiostats. It allows for an output of up to four analog signals at 16-bit resolution and an output voltage range of ±10 V. Additionally, the MIO provides f

Up to two MIO add-on cards can be addressed by the Zahner Lab software so that up to 8 analog output, 8 digital input, and 8 digital output channels can be handled.

Packing List

• MIO extension card

Installation

If the MIO card is purchased together with a basic device, it is already installed in the IM7/x system. Upgrading an IM7/x with MIO cards is very easy, as the cards only need to be inserted into the expansion slots provided. See IM7 Chapter for further information.

Note

The MIO plug-in card requires an expansion slot with a width of 4TE (corresponds to approx. 20mm). When upgrading, a new, smaller cover panel may be required for the remaining slots. This can be ordered as an accessory.

Connections

The MIO card features two BNC connectors and a D-SUB connector. The BNC connectors are assigned to the first two analog output channels.

The D-SUB port contains connectors for 4 analog outputs, 4 digital inputs and 4 isolated digital outputs.

Note

The complete pinout of the D-SUB port is shown below. The image shows the pinout with a view of the socket from the front.
