The input module AIH401-N is used for connection of active and/or passive 2-wire measuring transducer.

The module is functionally compatible with the

input modules AIH40-N and N-AIH41. In addition, the inputs are galvanically isolated. Configuration and parameterization are performed

only by the AIH40.. entry in the configuration

file (e.g GSD).

The analog value of 0…21 mA is digitzed as

a number between 0 and 21000. This corresponds to 1 μA per digit.

HART-compatible field devices that communicate directly with the relevant HART controller

can be connected to the module. HART multiplexing is thus no longer necessary and a

higher data throughput is achieved.

Up to 8 HART variables (max. 4 per channel)

can be transmitted via the cyclic user data to

the host system. Acyclic data exchange provides advanced communication options such

as the diagnostics and parameterization of

HART field devices.

The setting of parameters is initiated solely

by the host system. The following parameters

can be set for each channel:

■ Short circuit monitoring

■ Wire-break monitoring

■ Substitute value strategy

■ HART status/measuring range

■ HART variables

■ Input module for connection of passive

and/or active transmitters

■ Complete galvanic isolation

■ Transmission of HART data

■ One HART controller per channel for faster

access to HART data
