Instruction Sheet Bb 06/99
Reference variable generator 734 02
1. Prescribed use
The training panel is a component of the modular training panel system TPS 8.2 for automatic
control technology.
2. Location of use
Operate in dry rooms, which are suitable for experimenting with electrical operating equipment or
installations.
3.4. Description/function
If switch S
1 1 is in the lower position, the following signal may be tapped at output 2:
1. With a bridging plug connected to 3: – 10 V to + 10 V
2. With a bridging plug connect to 7: 0 V to + 10 V
If switch
S
1 1is in the upper position, a reference voltage or reference variable may be connected
to input 6.
If connections 5and 7are plugged in, then positive step changes from 0 V to the set end value
are generated by the switch 1.
Positive or negative outgoing step functions can be supplied with connection 5and 3.
The voltage value is determined by the setting of the reference variable generator 4.
Output 2 is buffered.
