9.7 THERMAL BEHAVIOUR
Surrounding air temperature 50°C. For ambient temperature of over 50°C, the output current must be
reduced by 2.5% per °C. Max 70°C At the temperature of 70°C the output current will be 50% of In. The
equipment does not switch off in case of ambient temperature above 70°C or thermal overload. The
devices are protected for Over temperature conditions "worst case"; in this situation the device Shut-down
the output and automatic restart when temperature inside fall.
10 MODBUS
Some devices are provided of Modbus "RTU" communication protocol port; which requires the only one
device be the Master, all the others must be slave.
Hardware interface: RS485.
10.1 ELECTRICAL CHARACTERISTICS

10.2 HOW TO CONNECT MODBUS
10.2.1 Daisy Chain general connection Diagram
To connect the device in ModBus field, please use AUX2 and AUX3 Port.
• Port: AUX 2 No. 13 is Present only in Sizes 3 and Sizes 4, MODBUS connection via RJ45 connector.
• Port: AUX 3 No. 14 Present only in Sizes 4. The function is the same of Auxiliary Output "AUX 2"
