(X32))
 In standard units, it consists of 5 output signaling relays (one of which is configurable), whose
common point is connected to pin 5.

 The communications line (COM) constitutes a very low safety voltage circuit. To preserve the
quality, it must be installed aside from other lines that have dangerous voltages (power distribution
line).
 In the same connector DB9 there are given both ports of communication of the equipment, the
RS-232 and the RS-485. Anyway it is not possible to use them simultaneously for being mutually
exclusive.
