VERSA POINT I/O MODULE

09/2002

6226B_GE

This data sheet is only valid in asso-
ciation with the System Manual.

Function

The terminal is designed for use within an
VersaPoint station. It is used to measure analog
voltage or current signals.

Features

–

Eight analog single-ended signal inputs for
the connection of either voltage or current si-
gnals

–

Sensors are connected using 2-wire techno-
logy

–

Various current and voltage measuring ran-
ges

–

Channels are configured independently of
one another using the bus

–

Measured values can be represented in five
different formats

–

16-bit analog-to-digital converter

–

Process data multiplex operation

–

Diagnostic indicators

The ANALOG IN 15 BIT VOLTAGE/
CURRENT 8CH terminal with
connectors

Please note that the connectors are
not supplied as standard with the ter-
minal. Please refer to the ordering
data on page 45 to order the appropri-
ate connectors for your application.
