Mark VIeS YAIC Analog I/O Pack
The Analog I/O pack (IS420YAICS1B) provides the electrical interface between one
or two I/O Ethernet networks and an analog I/O terminal board. The YAIC contains a
common
and an acquisition board specific to the analog input
function. The I/O pack is capable of handling up to 10 analog inputs, the first eight of
which can be configured as ±5 V or ±10 V inputs, or 4-20 mA current loop inputs. The
last two inputs can be configured as ±1 mA or 4-20 mA current inputs.
The load terminal resistors for current loop inputs are located on the terminal board
and voltage is sensed across these resistors by the YAIC. The I/O pack also includes
support for two 0-20 mA current loop outputs. The I/O pack receives or sends data
through dual RJ-45 Ethernet connectors to the controller and has a three-pin connector
to power it on. Output is through a DC-37 pin connector that connects directly with the
associated terminal board connector. Visual diagnostics are provided through indicator
LEDs.
