AOH40-N中文資料圖爾克數據手冊PDF規(guī)格書

The output module AOH40-N is used for the

connection of analog actuators such as control valves or process indicators.

The outputs are not galvanically isolated from

each other. When connecting the field devices, care has to be taken that all outputs are

on the same potential.

HART-compatible actuators that communicate

directly with the HART controller can be connected to the module.

The resolution is 13 bit, i.e. the analog value of 0…21 mA is represented as a number

between 0 and 8191. For easier operation,

the host system operates in a value range between 0…21000. This raw value is reduced by

the AOH40-N to a 13-bit resolution.

Parameters such as line monitoring, substitute

values etc. can be adjusted for each channel separately and are initialized solely by the

master.
