Operating
-40 °C...+70 °C
-40 °C...-30 °C: Proper start-up of system;
technical data not guaranteed
-40 °C...0 °C: Due to the LCD technology, the
display might respond very slowly.
-40 °C...+40 °C: Vertical mounting of modules
possible, output load limited to 50 % per group
+60 °C...+70 °C with the following deratings:
● System is limited to max. 2 communication
modules per terminal base
● Applications certified for cULus up to +60
°C
● Digital inputs: maximum number of simul-
taneously switched on input channels
limited to 75 % per group (e.g. 8 channels
=> 6 channels)
● Digital outputs: output current maximum
value (all channels together) limited to 75
% per group (e.g. 8 A => 6 A)
● Analog outputs only if configured as
voltage output: maximum total output
current per group is limited to 75 %
(e.g. 40 mA => 30 mA)
● Analog outputs only if configured
as current output: maximum number
of simultaneously used output chan-
nels limited to 75 % per group
(e.g. 4 channels => 3 channels)
