Operating Voltage Range: 20 to 280Vrms @47 to 63Hz. (140V
max when directly driving motorised
valves).
Current Rating: 0.01 to 1A (full cycle rms on-state @
25

Triac:
Isolation: Reinforced safety isolation from inputs
and other outputs.
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:
500
Ω maximum.
0 to 5V, 0 to 10V & 2 to 10V:
500
Ω minimum.
Short circuit protected.
Accuracy: ±
0.25% (mA @ 250 Ω , V @ 2k Ω ).
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/underdrive is applied (3.68 to
20.32mA and 1.84 to 10.16V).
Isolation: Reinforced safety isolation from inputs
and other outputs.
Linear DC:
