Page 32 The relays are divided into groups, according to the distance of insulation. Inside each group, the relays have just single insulation and thus must have the same voltage (generally 24Vac or 110÷230Vac). Between the groups there is double insulation and thus the groups can have different voltages. cod. Carel +030221826 rel. 2.0 dated 03/10/02...
Page 33 : the groups which feature between them are: 1, 2, 3, 4, 5, 6, 7 9, 10, 11, 12, 13 14, 15 16, 17, 18 * the main insulation is guaranteed between the output of one group. cod. Carel +030221826 rel. 2.0 dated 03/10/02...

Page 36 (node) to another. Each pCO can be connected to a CAREL supervisory network, using the optional PCO2004850 cards. The pCO terminals can monitor the control variables (temperature, humidity, pressure, I/O, alarms) from one or more boards. If one or more terminals are disconnected or malfunctioning, the control program continues to function correctly on each pCO main board.
