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.
