3.6.4 Additional Terminal Module TM31 (option G61)
One TM31 and two TM15 Terminal Modules are already part of each standard device version.
The Terminal Modules are used for the following functions:
● Inclusion of warning and fault messages and control signals
● Communication with a higher-level control level.
If the number of signals to be monitored is insufficient, the interface can be extended to include
an additional Terminal Module. Additional digital inputs and outputs and two analog inputs and
outputs are available with the TM31. The inputs and outputs are used, for example, for fetching
temperatures.
The TM31 Terminal Module provides the following inputs and outputs:
● 8 digital inputs
● 4 bidirectional digital inputs and outputs
● 2 relay outputs with changeover contact
● 2 analog inputs
● 2 analog outputs
● 1 temperature sensor input (KTY84-130/PTC)
Note
The second TM31 must be connected at the plant site.
The default setting of the inputs/outputs is not provided by the factory and must be
undertaken according to the requirements of the respective plant during commissioning.
When the analog inputs and outputs on the optional TM31 are used for communicating with the
control level, additional isolating transformers are available (optional).
3.6.5 Additional Terminal Module TM15 (option G63)
One TM31 and two TM15 Terminal Modules are already part of each standard device version.
The Terminal Modules are used for the following functions:
● Inclusion of warning and fault messages and control signals
● Communication with a higher-level control level.
With the optional additional Terminal Module TM15, you can also expand the number of digital
inputs and outputs. The expansion makes sense for the following applications:
● Reading in and processing external signals in addition to the existing terminal strip available
as standard.
● Controlling external components.
