Allen Bradley 1756-OA8E ControlLogix Module

Allen Bradley 1756-OA8E ControlLogix 8 Point Module

Description

The 1756-OA8E ControlLogix 120V AC Output Digital Module by Allen-Bradley is a digital output module installed in any slot on the ControlLogix chassis and it has 8 electronically-fused 120V AC outputs. It comes with an output voltage range of 74-132V AC at 47-63 Hz and an output linger time of 9.3ms at 60 Hertz and 11ms at 50 Hertz for ON/OFF and OFF/ON. The 1756-OA8E has a 200mA backplane draw current at 5.1V and 250mA at 24V and a total backplane power rating of 7.02 Watt. It has a power dissipation of 5.5 Watt and 18.76 BTU/hr thermal dissipation. The 1756-OA8E’s maximum OFF state leakage current is at 3mA per point and the voltage lost in its circuit peaks at 4V in the ON state.

The 1756-OA8E has a maximum current of 2A on each output point, and the gross current on the module’s outputs is 8A at 30 °C. The minimum load on each point is 10mA, and the circuit has a current surge of 20A for 43ms per point recurring every 2s. The 1756-OA8E’s isolation voltage is 125V adopting basic insulation type tested at 1200V AC for 2 seconds between outputs-to-backplane and output group-to-group. It is CE and UL-certified for industrial purpose and it is designated at the T4 temperature code and comes in an open-style enclosure. The 1756-OA8E’s optimal temperature ranges between 0 and 60 Celsius at 5-95% non-condensing relative humidity condition and it is stored and shipped at a temperature range between -40 and 85 °C.
