•
Overvoltage Category II for mains supply. The minimum and normal
category is II.
Pollution Degree:
•
I
−
in accordance with IEC 664
Channels
Number of Option Card Slots:
•
4
Number of Channels:
•
up to 64 channels, expandable to 128 with ChartScan expansion chassis
•
16 channels per card
• up to 4 cards installed in ChartScan
(up to 4 additional cards with use of ChartScan expansion chassis)
Channel Attributes:
•
High and low set points; hysteresis values for high and low set points.
Scan Sequence:
•
Any combination of temperature and voltage channels may be scanned, but
channels are scanned in ascending numerical order.
Scan Interval:
•
Absolute time between scans (
hh:mm:ss.t
); min = 00:00:00.0,
max = 99:59:59.9. Note: Specifying a value of 00:00:00.0 results in no delay
between channel scans.
