Publication 1769-IN055A-EN-P - April 2001
Output Specifications
Specification 1769-OA8
Voltage Category 100 to 240V ac
Operating Voltage Range 85V ac to 265V ac at 47 to 63 Hz
Number of Outputs 8
Bus Current Draw (max.) 145 mA at 5V dc (0.725W)
Heat Dissipation 2.12 Total Watts
(The Watts per point, plus the minimum Watts, with all
points energized.)
Signal Delay (max.) – resistive load (1)
(1) Turn On Type - Triac outputs turn ON and OFF at ac line zero cross.
turn-on = 1/2 cycle
turn-off = 1/2 cycle
Off-State Leakage (max.)
(2)
(2) Recommended Loading Resistor - To limit the effects of leakage current through solid state outputs, a loading resistor
can be connected in parallel with your load. For 120V ac operation, use a 15K
Ω , 2W resistor. For 240V ac operation use a
15K Ω , 5W resistor.
