Linear DC:
Resolution: Eight bits in 250mS
(10 bits in 1 second typical, >10 bits in >1
second typical).
Update Rate: Every control algorithm execution.
Ranges: 0 to 10V
0 to 5V
2 to 10V 0 to 20mA
4 to 20mA (default)
Load Impedance: 0 to 20mA & 4 to 20mA:
500Ω maximum.
0 to 5V, 0 to 10V & 2 to 10V:
500Ω minimum.
Short circuit protected.
Accuracy: ±0.25% (mA @ 250Ω, V @ 2kΩ).
Degrades linearly to ±0.5% for increasing
burden (to specification limits).
When used as control
output:
For 4 to 20mA and 2 to 10V a 2% over/
under-drive is applied (3.68 to 20.32mA and
1.84 to 10.16V).
Isolation: Reinforced safety isolation from inputs and
other outputs.
Use as 0 to 10VDC
transmitter power supply*
Indicators only.
Adjustable, 0.0 to 10.0V (regulated) output
into 500Ω minimum.
Transmitter Power Supply:
*see Linear output spec
for 0-10V PSU
Power Rating 19 to 28VDC (24V nominal) into 910Ω
minimum resistance.
Isolation: Reinforced safety isolation from inputs and
other outputs.
