2.3 Input Connections
Four input sources are accepted:
A. Non-isolated Frequency Inputs
Frequency (non-iso) card: Accepts non-isolated,
0 to 10 kHz @ 0.2 Vp-p minimum sine or square
wave signal inputs. This card requires dip switch
configuration prior to operation.
B. Isolated Frequency Inputs
Frequency (iso) card: Accepts isolated, 0 to
10 kHz @ 0.5 Vp-p minimum sine or square wave
signal inputs. No configuration required.
C. Analog Inputs
Two analog input cards are offered:
• Analog (iso) current, 4 to 20/0 to 20 mA
• Analog (iso) voltage, 0 to 5/0 to 10 VDC
Input ranges are software selectable, requiring no
internal configuration.
Note:
See section 4.4
for a listing of available input
cards.

To reduce the possibility of
noise interference, separate
input lines from AC power
lines.
