About 1746-OA8

The 1746-OA8 SLC 500 Digital AC output module by AB is an AC output module with 8 outputs and it can be installed in any slot on the SLC 500 I/O chassis. It has an AC operational voltage range between 85 and 265V AC at 47-63 Hertz and a backplane draw current of 0.185A at 5.0V DC and one of 0A at 24V DC. Electrical signals on the output point have a maximum load-dependent delay time of 1ms for ON and 11.0ms for OFF mode. The 1746-OA8 has a maximum leakage current of 2mA in its OFF state and the minimum current load on each output point is 10mA.

The maximum current on each output point is 1A which falls to 0.5A at 60 °C and the aggregate current on the 1746-OA8 module is 8A but it can fall to 4A at 60 °C. It has a drop voltage of 1.50V at 1A in its OFF state and the module has an output current surge of 10A for 25ms. The 1746-OA8’s factory-designated operational temperature falls between 0 and 60 °C (32 and 140 °F) and it must be used in 5-95% non-condensing relative humidity and stored at a temperature between 40 and 85 °C (-40 and 185 °F). It is built to withstand an operational vibration of 2.5G at 57-2000 Hertz and it can sustain a shock rating of 30G. The 1746-OA8 features NEMA standard ICS 2-230 Noise Immunity and is UL and CSA-certified.
