Description
This section contains installation information and requirements for the Siemens
FET Switch Adapter. The FET Switch Adapter (6ES7650-1BD51-0XX0 or
6ES7650-1BD50-0XX0) is used on the ET200M Marshalled Termination Assembly
(MTA) (6ES7650-1AH51-5XX0 or 6ES7650-1AH50-5XX0), which interfaces with
the Siemens ET 200M 6-Channel F Analog Input Module (6ES7 336-1HE00-0AB0,
E-Stand 4 or higher).
Note: The two part numbers are interchangeable.
9.15.2
Operation
The FET Switch Adapter contains optically coupled electronic switches powered by
the FAI modules VS supply. These switches break the input signal path and Mana
when power is lost on the FAI module or if the power supply in the FAI module
fails. See Figure 9–16.
This opening in the input signal path accomplishes two things:
•
First, if the power fails, all the electronics in the module are removed from the
circuit so that they cannot affect the other, still active, module.
•
Second, when power is restored and the switches close, the FAI module re-
integrates correctly into the configuration without causing bumps or process
fluctuations.
9.15.3
Installation Requirements
See Section 2,
, before performing any installation and observe all
warnings
The FET Switch Adapter is installed between
J1
on the MTA and the
interconnecting cable to the FAI Module. It should be screwed down to prevent
vibration or stress from disconnecting it from the MTA.
