Fig. 11: WTX 201 installation on top hat rail
1. Hook the WTX 201 relay module [A] onto the top hat rail so that it audibly engages.
2. Connect the WTX 201 relay module to the controller via an RS485 interface.
3. Check the input and output ports with the connection leads on site for the required
components.
4. Connect connection leads to the required components on site. Make sure the normally
closed and normally open function of the relay is operating correctly.
• Ensure that the RS485 bus terminating resistors are positioned. Only the last bus
participant must have the jumpers plugged in.
• For details on connecting and setting the jumpers, see chapter "18.2 Connection
