A 5 Tested successfully: use under extreme ambient
conditions
The Inline controllers (ILC 131 ETH/XC, ILC 151 ETH/XC) have been tested successfully
over 250 temperature change cycles according to IEC 61131-2 in the range from -40°C to
+70°C.
The following conditions were observed:
– The Inline devices for all connecting cables were connected with a minimum conductor
cross section of 0.5 mm
– The Inline controller was installed on a wall-mounted horizontal DIN rail.
– Fans were used to ensure continuous movement of air in the control cabinet.
– The Inline controller was not exposed to vibration or shock.
– The Inline controller was operated with a maximum of 24.5 V (ensured by using elec-
tronically regulated power supply units).
