within 15 minutes.
Input/Output Isolation (Optional):
600 VRMS, 1
minute.
Supply Voltage:
Non-Isolated: 10 to 45 volts DC with no load.
Isolated: 13 to 45 volts DC with no load.
Reverse polarity protected.
Voltage effect:
+/- 0.001% of span per volt.
Lead Wire Compensation (3-wire RTD):
+/- 0.05% of
span per ohm, up to 25 ohms in each leg.
Maximum Load Resistance:
The maximum allowable
resistance of the signal-carrying loop is given by this
formula:
Non-Isolated: Rloop max = (Vsupply-10)/.02
amps)
Isolated: Rloop max = (Vsupply-13)/.02
amps)
