Fig. 4: WTX 201
With the WTX 201 8-fold relay module, the WTC 200 controller can be extended by 8 relay
output ports. The relay output ports can be used to connect items such as control units for lifts.
In addition, the WTX 201 has an analogue/digital input port. The WTX 201 is connected to
the WTC 200 controller via an RS-485 interface. Up to eight 8-way relay modules can be
cascaded one after the other. This also corresponds to the maximum number that can be
connected to a controller. The WTX 201 8-way relay module is attached to a "TS 35" top
hat rail in accordance with EN 50022.
