3.6.3
Isolation amplifiers for optional analog inputs (option E86)
This option provides two isolation amplifiers if an additional TM31 Terminal Module is provided
as an extension of the customer interface and the TM31 analog inputs are to be used with a
higher-level control level for communication purposes. Multifunction interface converters with
the following adjustment range are used:
● 0 V to 10 V
● 0 mA to 20 mA
● 4 mA to 20 mA
The range must be set on the isolating transformer.
3.6.4
Isolation amplifiers for optional analog outputs (option E87)
This option provides two isolation amplifiers if an additional TM31 Terminal Module is provided
as an extension of the customer interface and the TM31 analog inputs are to be used with a
higher-level control level for communication purposes. Multifunction interface converters with
the following adjustment range are used:
● 0 V to 10 V
● 0 mA to 20 mA
● 4 mA to 20 mA
The range must be set on the isolating transformer.
3.6.5
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
