Power
Consumption
16 VA maximum (100 to 240 Vac)
12 VA maximum (24 Vac/dc)
Power Inrush
Current
1.84 A maximum for 5.25 ms (under operating conditions),
reducing to a maximum of 200 mA (100 to 240 Vac operation) or
312 mA (24 Vac/dc operation) after 8.42 ms.
CAUTION: When applying power to more than one
instrument, make sure that sufficient power is supplied.
Otherwise, the instruments may not start up normally due to
voltage drop from the inrush current.
Weight 3 lbs. (1.3 kg)
Isolation
(Functional)
AC Power(100~240VAC): Electrically isolated from all other inputs
and outputs to withstand a HIPOT potential of 3000 Vac for 60
seconds, from earth ground to withstand a HIPOT potential of
1500 Vac for 60 seconds per EN61010-1.
DC Power(24VDC/AC): Electrically isolated from all other inputs and
outputs and earth ground to withstand a HIPOT potential of 840
Vac for 60 seconds per EN61010-1.
Analog Inputs and Outputs, Digital Inputs and Outputs: Electrically
isolated from all other circuits to withstand a HIPOT potential of
1500 Vac for 60 seconds.
Relay Contacts: With a working voltage of 125/250 Vac, these are
electrically isolated from all other circuits to withstand a HIPOT
potential of 3000 Vac for 60 seconds per EN61010-1.
Surge Withstand
Capability (SWC)
Immunity: ANSI/IEEE C37.90.1, Surge Withstand Capability (SWC)
(Formerly IEEE 472). Mains power input and relay contact outpus:
2.5 kV, Common Mode and Differential Mode. All other circuits: 1.0
