Alarm relay
Five relay outputs, NO
(normally open); maximum
250 V/6 A, maximum 550 VA
ohmic load
• two relays for the limit
values of each of the two
sensors
• one alarm relay; free
assignment to the limit
values or to sensor test
(see below.
• Two measured value inputs
(for amperometric sensors 1
and 2)
• Two current outputs
(0) 4-20 mA, maximum
load of 400 Ω, assigned to
the 0-5 ppm range
• Limit value 1 (preliminary
warning if exceeded) can
be set to any value within
the measuring range.
• Limit value 2 (warning if
exceeded) can be set to
any value within the
measuring range.
• Limit value 2 can be
delayed between 0-200
seconds.
• Hysteresis: 0 - 0.5 ppm.
• Limit value 1 and 2 can be
acknowledged. The
acknowledgement is
stored in a list of events.
The alarm relay can be
assigned to any of the limit
values and/or the sensor test.
