2.1. Hardware Installation
Please refer to the RYMASKON 200 installation sheet for further information on dimensions, mounting and
wiring.
Figure 2 shows the back view of the device with the connection terminals for Modbus, 24 V DC-Supply and
external buttons. The four external buttons share a common GND connection which is internally connected to the
negative 24 V input terminal.
The external button terminal EB3 is also capable of sensing a NTC-10k temperature sensor. The temperature value
of the sensor will be provided on Modbus register address 49 (see Table 10 on Page 21). The cable length for
connecting the temperature sensor must not exceed 150m for 0.5mm² or 70m for 0.25mm² to guarantee a
temperature error less than 0.1% at 25°C.
