Output type: Isolated output programmable as
- 0-20 mA
- 4-20 mA.
Scaling: programmable from -1999 to 9999.
Maximum load: 600
W.
Accuracy:
- 0.1 % when it is used as control output
- 0.05 % when it is used as analog retransmission. Note: a too
little range scaling can deteriorate the output accuracy.
Filter: It is possible to apply a first order digital filter on the
retransmitted value.
The time constant of the filter may be programmed within 0 and
8 s.
Additional 5 + 5 outputs (OUT10 to 19)
Function: singularly programmable as Event output.
Type: Relay .
Relay type: SPST
Contact rating: 0.5 A @ 250 V on resistive load.
Note: The commons of the out 10 to 14 connected together with
the terminal 66 while the commons of the output 15 to 19 are
connected with terminal 55.
ALARMS
Alarm action: direct or reverse function programmable.
Alarm functions: each alarm can be configured as process
alarm, band alarm, deviation alarm, alarm on main or secondary
control output value.
Alarm reset: automatic or manual reset programmable on each
alarm.
Alarm masking: each alarm can be configured as masked
alarm or standard alarm.
This function allows to delete false indication at instrument start
up and after a set point change.
Process alarm:
Operative mode: Minimum or maximum programmable.
Threshold: programmable in engineering unit within the input
range.
Hysteresis: programmable in engineering units from 1 to 200
digits.
Band alarm
Operative mode: Inside or outside programmable.
Threshold: two thresholds programmable:
- Low - from 0 to -1000 digits.
- High - from 0 to +1000 digits.
Hysteresis: programmable in engineering units from 1 to 200
digits.
