Connection
Connection of power and communication. Suitable cable types are LAM DATAPAR 2x0.8
(cross-section in mm
2
), JYTY 2x1 (diameter in mm) etc. If communication and power are
in the same cable, use 4-core LAM DATAPAR 2x2x0.8, JYTY 4x1. Up to 100-120 meters,
parallel lines of 24 V and data bus are no problem. Regarding to EMC it is better if the
pairs are twisted, such as with the LAM DATAPAR or Belden 8205 cable.
A terminal is designed for maximum 3 wires of 0.8 mm
2
.
