The 1771-OMD PLC 5 Digital Output Module by Allen-Bradley is a fused output module installed in a single slot of the 1771 I/O chassis. The module has 16 outputs with an output voltage range between 184 and 250V AC at 47 - 63Hz and an output current of 2A for each output and an aggregate current that must exceed 8A for the entire module. The module has a surge current of 25A which flows on each output for 100ms and keeps recurring every 1 second and 25A on the entire module for 100ms that is repeatable every 1 second. The 1771-OMD requires 10mA per output at 220V AC (60Hz) minimum current load to remain ON and the maximum voltage loss in the ON state is 1.5V at 2A. It has 4mA per output at 220V AC OFF state leakage current and the maximum signal delay time on the outputs is 10ms for ON and 8.3 to 9.1ms for OFF at 60Hz. The 1771-OMD has a minimum power dissipation of 3.7 Watts which maxes at 17.3 Watts when operational and the maximum operational thermal dissipation is 59 BTU/hr. It draws a backplane current of 700mA at 5V DC (+5%) and offers circuit voltage isolation which meets or exceeds UL and CSA standards. The 1771-OMD requires a standard field wiring arm or an optional fused wiring arm with a wiring screw torque of 7 - 9 inch pounds and all outputs are fused with 10A 250V rectifier fuse (1/4 x 1-1/4 inch). It has a working temperature bracket between 0 and 60 0C (32 and 140 0F) around a 5-95% humidity condition without condensation and it has a designated -40-85 0C (-40-185 0F) storage temperature range.
