STANDARD RANGES TABLE
LOGIC INPUTS
The instrument may be supplied with 3 logic inputs each one of
them can be programmed as:
- Set point selection (SP-SP2)
- Set point selection (SP3-SP4)
- Local/remote set point selection
- Auto/manual selection
- Output limiter activation
- Data Hold of the measured value
- Manual reset of the alarms
(acknowledge)
- Reverse/direct control action
Input type: Contact closure (voltage free).
Active logic level: Close or open programmable.
CURRENT TRANSFORMER INPUT FOR OUT FAILURE
DETECTION
The instruments equipped with this feature are capable, by
means of a CT, to detect and signal a possible failure of the line
driven by a control output programmed as a time proportioning
output (see "OUT failure detection").
Input range: 50 mA AC.
Scaling: programmable from 10 A to 100 A (with 1 A step).
Resolution:
- for full scale up to 25 A: 0.1 A.
- for full scale from 26 A to 100 A: 1 A
Minimum duration of the period (ON or OFF) to perform the
measurement: 120 ms.
