Data Sheet

B
Analogue override module - Auto/Hand
(0…10)V
• Analogue output module intended to provide,
by the selection switch on the front panel, a
(0…10)V output, automatically or by hand.
• With the selector switch in position “A“
(Automatic) the (0…10)V signal is derived
from the controller.
In position “H” (Hand) the controller signal is
ignored and the (0…10)V signal is derived
directly from the potentiometer setting on the
facia of the module
• The level of the (0…10)V output signal is
displayed by 3 green LEDs, set at >25%, >50%
and >75%.
• 24VAC/DC supply
• 35mm rail (EN60715) mounting
Application examples:
• permits the direct control of proportional
valves under exceptional circumstances or
where the automatic controller has failed
