Function

Application range
Upon installation in a suitable enclosure, the HART Analog Universal Module
Type 9468/32 can used in gas and dust hazardous areas of Zones 1, 2, 21, and 22 or
in safe areas. The device must be used in areas with a degree of pollution of 1 or 2.
Mode of operation
The HART Analog Universal Module can be used to connect up to eight intrinsically safe
analog unit signals (0/4 to 20 mA) to the IS1+ remote I/O system. Digital communication
with connected field devices can take place in both directions using the HART protocol.
Each channel can be parameterised as input for connecting 2-wire transmitters including
transmitter supply or as output for connecting positioners or indicators. The Ex i inputs or
outputs are short-circuit proof and galvanically separated from the system.
Function-compatible replacement for IS1 I/O modules:
Series 9460/12*, 9461/12*, 9465/12 and 9466/12.
* operation with active 4-wire HART transformers also requires a 9164 for each channel.
