Module Restrictions - Siemens ET 200M Manual

Note
Fuses are available as spare parts from Siemens.
Fuse information can be found at:

Note
When using a 1.5A channel fuse it is possible that one or more of the zener
diodes on the two Zener Diode Boards may be damaged in the event of a short
circuit in the field. It is recommended that the diode boards be tested or replaced
in the event a 1.5A channel fuse opens.

6-Channel F Analog Input MTA
Only 1 transmitter can be connected to a
channel.
0 – 20 mA & 4 – 20 mA
None. Voltage Mode not available
FET Switch Adapter current consumption = 25

The MTA and an 8 meter cable add
±0.3% to the error limit specification of
the module for channels 0 - 3. The 3
meter cable adds ±0.1%.
To improve the accuracy with the MTA,
use the following configuration:
Module Parameter- Type of Sensor
Interconnection: 2 Sensors (There is
actually only one sensor connected.)
Channel Parameter- Unit Value: MIN
(Unit Value refers to the value returned by
the F-AI module to the CPU.)
