• Digital outputs with free drives
If a terminal X1.5 to X8.5 of the bus module is not allocated, a relay with 24 V
d.c. coil can be connected for free use (fig. 1). The free circuit is integrated.
The driver current is maximum 120mA per output.
Ventilation cabinets, auxiliary heating, circuit breakers or control lamps for
example, can be activated with this via the Modbus.

3.2 SETPOInT PROCESSInG Thyro-A/Thyro-AX

The setpoint processing depends on how the bus module is connected to the
power controller. for Thyro-A/Thyro-AX different variations can be realised
depending on the requirements. The connection of terminal X22.1 of Thyro-
A/Thyro-AX controls the procedures (Chapt. 7, fig. 3).
• no connection to X22.1
The bus module is fully functional, however, only the analog signal of con-
trol terminal X2.4 is used as the setpoint.
• X22.1 has ground potential
Only the master setpoint is accepted by the bus module as a setpoint. The
controller's terminal X22.1 can be directly connected to earth if an alternati-
ve operation is excluded.
• X22.1 is switched
• The terminal X22.1 of Thyro-A/Thyro-AX is connected to one of the termi-
nals X1.1 to X8.1 of the bus module (fig. 3).
With malfunctions on the bus line all controllers are automatically swit-
ched over to the respective analog signal of the setpoint input of Thyro-A/
Thyro-AX.
• The circuit X22.1 of Thyro-A/Thyro-AX is connected to one of the terminals
X1.5 to X8.5 of the bus module (fig.3). Then each controller can be switched
individually (selectively) via bus to „hand".
With malfunctions on the bus line the last setpoint is automatically retai-
ned.
• Digital outputs with free drives
If a terminal X1.5 to X8.5 of the bus module is not allocated, a relay with 24
V d.c. coil can be connected for free use (fig. 1). The free circuit is integrated.
The driver current is maximum 120 mA per output.
Ventilation cabinets, auxiliary heating, circuit breakers or control lamps, for
example, can be switched via the Modbus.
