This plug-in I/O module integrates data to/from other devices and is field expandable. It provides added functions and increased versatility for any of the Avuvim II Series. These increased functions can be enabled by simply snapping on the module to the back of either meter and can work in conjunction with two other extension modules (cannot be paired with the same module). This module features 4 Digital Inputs, 2 Digital Outputs, and 2 Analog Outputs of 4 to 10mA.
